wind & willow seasoning

The wind is also an important means of transportation for seeds and small birds; with time things can travel thousands of miles in the wind. [124] Plant varieties near the coast, such as the Sitka spruce and sea grape,[125] are pruned back by wind and salt spray near the coastline. Geostationary satellite imagery can be used to estimate the winds throughout the atmosphere based upon how far clouds move from one image to the next. For instance, species in the Asteraceae on islands tended to have reduced dispersal capabilities (i.e., larger seed mass and smaller pappus) relative to the same species on the mainland. A brief treatment of winds follows. According to legend, he was present at the creation of the world and first let the winds out of his bag to clear the world of mist. Learn more. In areas where there is rugged topography that significantly interrupts the environmental wind flow, the wind circulation between mountains and valleys is the most important contributor to the prevailing winds. Definition of wind in the Idioms Dictionary. Cassini–Huygens data indicated peak easterly winds of 375 meters per second (840 mph). [79] There are also four dvärgar (Norse dwarves), named Norðri, Suðri, Austri and Vestri, and probably the four stags of Yggdrasil, personify the four winds, and parallel the four Greek wind gods. Westerly winds in the mid-latitudes of the planet drive the movement of ocean currents from west to east across the world's oceans. Together with the trade winds, the westerlies enabled a round-trip trade route for sailing ships crossing the Atlantic and Pacific Oceans, as the westerlies lead to the development of strong ocean currents on the western sides of oceans in both hemispheres through the process of western intensification. [151], Rather than air, the solar wind is a stream of charged particles—a plasma—ejected from the upper atmosphere of the sun at a rate of 400 kilometers per second (890,000 mph). [79] Venti are the Roman gods of the winds. Wind applies to any such air in motion, blowing with whatever degree of gentleness or violence. [85] During Napoleon's Egyptian Campaign, the French soldiers had a hard time with the khamsin wind: when the storm appeared "as a blood-stint in the distant sky", the Ottomans went to take cover, while the French "did not react until it was too late, then choked and fainted in the blinding, suffocating walls of dust". Downslope winds also occur in the foothills of the Appalachian mountains of the United States,[55] and they can be as strong as other downslope winds [56] and unusual compared to other foehn winds in that the relative humidity typically changes little due to the increased moisture in the source air mass. Wind is the movement of air from an area of high pressure to an area of low pressure. This triggers the main shaft of the wind turbine, connected to a gearbox within the nacelle, to spin. The kinetic energy of a packet of air of mass m with velocity v is given by ½ m v2. [52], In mountainous areas, local distortion of the airflow becomes severe. [158] Other Martian winds have resulted in cleaning events and dust devils. On the surface of the Earth, wind consists of the bulk movement of air. before the 12th century, in the meaning defined at sense 1a, 15th century, in the meaning defined at transitive sense 2, before the 12th century, in the meaning defined at transitive sense 1a, 14th century, in the meaning defined at sense 4, 1586, in the meaning defined at transitive sense 1, Middle English, from Old English; akin to Old High German wint wind, Latin ventus, Greek aēnai to blow, Sanskrit vāti it blows, Middle English, from Old English windan to twist, move with speed or force, brandish; akin to Old High German wintan to wind, Umbrian ohavendu let him turn aside. [46] As the temperature of the surface of the land rises, the land heats the air above it by conduction. The United States reports winds over a 1‑minute average for tropical cyclones,[12] and a 2‑minute average within weather observations. When the wind blows, the wind turbine's blades spin clockwise, capturing energy of the wind. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator. [136] Elk have a keen sense of smell that can detect potential upwind predators at a distance of 0.5 miles (800 m). [50] Wind direction also changes because of the contour of the land. Roofs severely stripped; mobile homes overturned or badly damaged; loss of exterior doors; windows and other glass broken. Except for rotor ships using the Magnus effect, every sailing ship has a hull, rigging and at least one mast to hold up the sails that use the wind to power the ship. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. This may be caused by the wind blowing over cavities, or by vortices created in the air downstream of an object. [53] Winds that flow over mountains down into lower elevations are known as downslope winds. [86] During the North African Campaign of the World War II, "allied and German troops were several times forced to halt in mid-battle because of sandstorms caused by khamsin ... Grains of sand whirled by the wind blinded the soldiers and created electrical disturbances that rendered compasses useless. They are useful for simplifying the atmospheric equations of motion and for making qualitative arguments about the horizontal and vertical distribution of winds. Wind is the flow of gases on a large scale. The study showed that the seedlings responded to the damage created by the windblown sand abrasion by shifting energy from stem and root growth to the growth and repair of the damaged stems. Widespread significant wind damage can occur with higher wind speeds. In coastal regions, sea breezes and land breezes can be important factors in a location's prevailing winds. [81] In Norse mythology, Njörðr is the god of the wind. He is said to be the ancestor (grandfather) of the winds of the eight directions. [102], Wind figures prominently in several popular sports, including recreational hang gliding, hot air ballooning, kite flying, snowkiting, kite landboarding, kite surfing, paragliding, sailing, and windsurfing. Wind energy is the kinetic energy of the air in motion. Wind causes the generation of sound. Turbines are designed to operate within a specific range of wind speeds. The trade winds (also called trades) are the prevailing pattern of easterly surface winds found in the tropics towards the Earth's equator. Black Friday Offer $55 for 20GB, Plus a Galaxy S20 FE 5G On Us. Worldwide animated weather map, with easy to use layers and precise spot forecast. Another word for wind. Directly under the subtropical ridge are the doldrums, or horse latitudes, where winds are lighter. Infrequent wind gusts can cause poorly designed suspension bridges to sway. Wind speeds during downslope wind effect can exceed 160 kilometers per hour (99 mph).[58]. The limits of the range are known as the cut-in speed and cut-out speed. In Java, the local name for such winds is koembang. Entire stories of well-constructed houses destroyed; severe damage to large buildings such as shopping malls; trains overturned; trees debarked; heavy cars lifted off the ground and thrown; structures with weak foundations are badly damaged. [64] Wind shear can be broken down into vertical and horizontal components, with horizontal wind shear seen across weather fronts and near the coast,[65] and vertical shear typically near the surface,[66] though also at higher levels in the atmosphere near upper level jets and frontal zones aloft. It consists mostly of electrons and protons with energies of about 1 keV. Winds have various aspects: velocity (wind speed); the density of the gas involved; energy content or wind energy. Wind turbines allow us to harness the power of the wind and turn it into energy. Hills and valleys substantially distort the airflow by increasing friction between the atmosphere and landmass by acting as a physical block to the flow, deflecting the wind parallel to the range just upstream of the topography, which is known as a barrier jet. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). But how is wind energy created? There are also strong evolutionary constraints on this dispersal mechanism. Updated every three hours. “Wind.” Dictionary, Merriam-Webster, Although wind is not the primary form of seed dispersal in plants, it provides dispersal for a large percentage of the biomass of land plants. [163][164][165] At the cloud tops of Neptune, prevailing winds range in speed from 400 meters per second (890 mph) along the equator to 250 meters per second (560 mph) at the poles. Winds of this strength due to downsloped winds off terrain have been known to shatter windows and sandblast paint from cars. Wind powers the voyages of sailing ships across Earth's oceans. In Central America, examples include the Papagayo wind, the Panama wind, and the Tehuano wind. What does wind expression mean? Wind dispersal can take on one of two primary forms: seeds can float on the breeze or alternatively, they can flutter to the ground. Loess often stands in either steep or vertical faces. (moving air) vent nm nom masculin: s'utilise avec les articles "le", "l'" (devant une voyelle ou un h muet), "un". The pilot must adjust the airspeed to deal with the effect of the gradient. [93], For aerodynamic aircraft which operate relative to the air, winds affect groundspeed,[94] and in the case of lighter-than-air vehicles, wind may play a significant or solitary role in their movement and ground track. Total wind power could be captured only if the wind velocity is reduced to zero. Internet 50Mbps, τηλεόραση WIND VISION με περισσότερα από 60 συνδρομητικά κανάλια & δώρο Wi-Fi Extender για κάλυψη σε κάθε γωνιά του σπιτιού! Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. When these winds blow over open waters, they increase mixing of the upper layers of the ocean that elevates cool, nutrient rich waters to the surface, which leads to increased marine life. Ocean roughness can be used to estimate wind velocity close to the sea surface over oceans. Each half of a flag depicts 5 knots (9.3 km/h) of wind. "[87], There are many different forms of sailing ships, but they all have certain basic things in common. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere. There is a large variability in the dust transport to the Caribbean and Florida from year to year. [127] After a period of four weeks, the growth of the seedling once again became uniform throughout the plant, as it was before the windblown sand abrasion occurred. A relation between the input and output wind velocity must be considered. [110] Loess deposits are geologically unstable by nature, and will erode very readily. CanWEA is the voice of Canada’s wind energy industry, actively promoting the responsible and sustainable growth of wind energy. One study indicates that an entirely renewable energy supply based on 70% wind is attainable at today's power prices by linking wind farms with an HVDC supergrid. Can you spell these 10 commonly misspelled words? [15] A short burst of high speed wind is termed a wind gust, one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval by 10 knots (5 m/s) for periods of seconds. (with Digital Discount) 3 Big Gig Unlimited 4 data plan with 20GB of Fast LTE data and get the Samsung Galaxy S20 FE 5G for Absolute Zero TM 9. In the coldest climates such as Antarctica, emperor penguins use huddling behavior to survive the wind and cold, continuously alternating the members on the outside of the assembled group, which reduces heat loss by 50%. How to use windup in a sentence. While taking off with a tailwind may be necessary under certain circumstances, a headwind is generally desirable. 'Cease' vs. 'Seize': Explaining the Difference. Wind pressures are positive on the windward side of a structure and negative on the leeward side. In mountainous parts of the world subjected to relatively consistent winds (for example, the trade winds), a more moist climate usually prevails on the windward side of a mountain than on the leeward or downwind side. [92] Sailing ships can only carry a certain quantity of supplies in their hold, so they have to plan long voyages carefully to include appropriate provisions, including fresh water. It is a calculation relating to the effective force of the wind at a particular location, frequently expressed in terms of the elevation above ground level over a period of time. [97] The furnaces were constructed on the path of the monsoon winds to exploit the wind power, to bring the temperatures inside up to 1,200 °C (2,190 °F). Below is the scale. Sign up for a $55/mo. Wind, in climatology, the movement of air relative to the surface of the Earth. METAR, TAF and NOTAMs for any airport in the World. [157] When the poles of Mars are exposed to sunlight after their winter, the frozen CO2 sublimates, creating significant winds that sweep off the poles as fast as 400 kilometers per hour (250 mph), which subsequently transports large amounts of dust and water vapor over its landscape. [14] Knowing the wind sampling average is important, as the value of a one-minute sustained wind is typically 14% greater than a ten-minute sustained wind. [16] Alternatively, movement of the parent weather balloon position can be tracked from the ground visually using theodolites. Most ocean basins use the average wind speed to determine the tropical cyclone's category. SYNOP codes from weather stations and buoys. The relationship between wind speed and power for a typical wind turbine is shown in Figure 2. The strongest observed winds on a planet in the [100] Horizontal-axle windmills were later used extensively in Northwestern Europe to grind flour beginning in the 1180s, and many Dutch windmills still exist. In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. [30] The trade winds act as the steering flow for tropical cyclones that form over the world's oceans. [88] Ocean journeys by sailing ship can take many months,[89] and a common hazard is becoming becalmed because of lack of wind,[90] or being blown off course by severe storms or winds that do not allow progress in the desired direction. [118] The Shamal is caused by cold fronts lifting dust into the atmosphere for days at a time across the Persian Gulf states. [3] The thermal wind is the difference in the geostrophic wind between two levels in the atmosphere. [105], During mid-summer (July in the northern hemisphere), the westward-moving trade winds south of the northward-moving subtropical ridge expand northwestward from the Caribbean into southeastern North America. Well-constructed and whole frame houses completely leveled; some frame homes may be swept away; cars and other large objects thrown and small missiles generated. So, we find that the total wind energy is: Differentiating with respect to time to find the rate of increase of energy, we find that the total wind power is: Wind power is thus proportional to the third power of the wind velocity. In outer space, solar wind is the movement of gases or charged particles from the Sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. [10] Another type of anemometer uses pitot tubes that take advantage of the pressure differential between an inner tube and an outer tube that is exposed to the wind to determine the dynamic pressure, which is then used to compute the wind speed.[11]. [13] India typically reports winds over a 3‑minute average. [76] The thermal wind concept explains how differences in wind speed with height are dependent on horizontal temperature differences, and explains the existence of the jet stream. The strongest observed winds on a planet in the Solar System occur on Neptune and Saturn. [77], As a natural force, the wind was often personified as one or more wind gods or as an expression of the supernatural in many cultures. What does wind expression mean? Windup definition is - the act of bringing to an end. As described earlier, prevailing and local winds are not spread evenly across the earth, which means that wind speeds also differ by region. [119], Wind dispersal of seeds, or anemochory, is one of the more primitive means of dispersal. Moisture is removed by orographic lift, leaving drier air on the descending and generally warming, leeward side where a rain shadow is observed. Wind affects animals' food stores, as well as their hunting and defensive strategies. Unlike the Westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. In Poland, an example is the halny wiatr. [135] Cockroaches use slight winds that precede the attacks of potential predators, such as toads, to survive their encounters. How to use wind in a sentence. [115] The Harmattan carries dust during the winter into the Gulf of Guinea. The blast wave is similar to a strong wind gust over the ground. [106], There are local names for winds associated with sand and dust storms. [140] Wind speeds as low as 23 knots (43 km/h) can lead to power outages due to tree branches disrupting the flow of energy through power lines. On the surface of the Earth, wind consists of the bulk movement of air. [161] Saturn's winds are among the Solar System's fastest. [159][160] On Jupiter, wind speeds of 100 meters per second (220 mph) are common in zonal jet streams. The larger the WPD calculation, the higher it is rated by class. [148], The hydrodynamic wind within the upper portion of a planet's atmosphere allows light chemical elements such as hydrogen to move up to the exobase, the lower limit of the exosphere, where the gases can then reach escape velocity, entering outer space without impacting other particles of gas. [99] Made of six to twelve sails covered in reed matting or cloth material, these windmills were used to grind corn and draw up water, and were used in the gristmilling and sugarcane industries. [79] Aeolus, in varying interpretations the ruler or keeper of the four winds, has also been described as Astraeus, the god of dusk who fathered the four winds with Eos, goddess of dawn. [83] Protestant Wind is a name for the storm that deterred the Spanish Armada from an invasion of England in 1588 where the wind played a pivotal role,[84] or the favorable winds that enabled William of Orange to invade England in 1688. It takes into account wind velocity and mass. When combined with cold temperatures, the wind has a negative impact on livestock. [153] Planets require large magnetic fields in order to reduce the ionization of their upper atmosphere by the solar wind. [105] The general wind circulation moves small particulates such as dust across wide oceans thousands of kilometers downwind of their point of origin,[106] which is known as deflation. The solar wind creates the Heliosphere, a vast bubble in the interstellar medium surrounding the Solar System. [128], Cattle and sheep are prone to wind chill caused by a combination of wind and cold temperatures, when winds exceed 40 kilometers per hour (25 mph), rendering their hair and wool coverings ineffective. [166] At 70° S latitude on Neptune, a high-speed jet stream travels at a speed of 300 meters per second (670 mph). [109] Loess tends to develop into highly rich soils. Below is a summary of the classifications used by Regional Specialized Meteorological Centers worldwide: The Enhanced Fujita Scale (EF Scale) rates the strength of tornadoes in the United States by using damage to estimate wind speed. Its speed is 20,000,000 miles per hour (32,000,000 km/h), which is 3% of the speed of light. For example, burn rates of smoldering logs are up to five times greater during the day because of lower humidity, increased temperatures, and increased wind speeds. Isotachs are particularly useful in diagnosing the location of the jet stream on upper-level constant pressure charts, and are usually located at or above the 300 hPa level.[26]. Ex : garçon - nm > On dira "le garçon" ou "un garçon". Wind engineering describes the study of the effects of the wind on the built environment, including buildings, bridges and other man-made objects. [67], Wind shear itself is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. [7] Weather vanes pivot to indicate the direction of the wind. Wind power generation plays an increasingly important role in the way we power our world – in a clean, sustainable manner. Faster rotation translates to more mechanical power and more electrical power from the generator. The Egmond aan Zee wind farm off the Dutch coast is a 50-50 joint venture between European utility company Nuon and Shell. This type of gas loss from a planet into space is known as planetary wind. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. [133] Bird migration, which tends to occur overnight within the lowest 7,000 feet (2,100 m) of the Earth's atmosphere, contaminates wind profiles gathered by weather radar, particularly the WSR-88D, by increasing the environmental wind returns by 15 knots (28 km/h) to 30 knots (56 km/h). Find all the weather maps, satellite and radar maps, weather conditions and explanations you're looking for. [58] Once winds exceed 135 knots (250 km/h), homes completely collapse, and significant damage is done to larger buildings. The basic relation that the turbine power is (approximately) proportional to the third power of velocity remains. Wind also affects the spread of wildfires. Peels surface off some roofs; some damage to gutters or siding; branches broken off trees; shallow-rooted trees pushed over. This temperature change causes the daytime sea breeze to dissipate. High winds scour away thin soils through erosion,[123] as well as damage limbs and twigs. [116] The Sirocco brings dust from north Africa into southern Europe because of the movement of extratropical cyclones through the Mediterranean. If the wind gradient is significant or sudden, or both, and the pilot maintains the same pitch attitude, the indicated airspeed will increase, possibly exceeding the maximum ground launch tow speed. To determine winds aloft, rawinsondes determine wind speed by GPS, radio navigation, or radar tracking of the probe. Weather radar, wind and waves forecast for kiters, surfers, paragliders, pilots, sailors and anyone else. In fact, wind exists because the sun unevenly heats the surface of the Earth. Confirmed tornadoes with no reported damage (i.e., those that remain in open fields) are supposed to be rated EF0 as a matter of policy; however, some NWS local offices have adopted an "EFU" (for "unknown") rating for such tornadoes.[23]. For full treatment, see climate: Wind. Nowadays, a yardstick used to determine the best locations for wind energy development is referred to as wind power density (WPD). Globally, the two major driving factors of large-scale wind patterns (the atmospheric circulation) are the differential heating between the equator and the poles (difference in absorption of solar energy leading to buoyancy forces) and the rotation of the planet. [32], A monsoon is a seasonal prevailing wind that lasts for several months within tropical regions. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network. In New Zealand, they are known as the Nor'west arch, and are accompanied by the cloud formation they are named after that has inspired artwork over the years. [144] The most powerful gusts of wind on Earth were created by nuclear detonations. “Wind gusts may approach or exceed 110 km/h in wind-prone areas.” In southwestern Alberta, Environment Canada said wind gusts as high as 120 km/h are expected in some areas. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. [111] Over 50% of the African dust that reaches the United States affects Florida. [103] When landing, wind shear is also a hazard, particularly when the winds are strong. [72] Wind shear has a significant effect on the control of aircraft during take-off and landing,[73] and was a significant cause of aircraft accidents involving large loss of life within the United States. What made you want to look up wind? Australia's Barrow Island holds the record for the strongest wind gust, reaching 408 km/h (253 mph) during tropical cyclone Olivia on 10 April 1996, surpassing the previous record of 372 km/h (231 mph) set on Mount Washington (New Hampshire) on the afternoon of 12 April 1934. Within the Beaufort scale, gale-force winds lie between 28 knots (52 km/h) and 55 knots (102 km/h) with preceding adjectives such as moderate, fresh, strong, and whole used to differentiate the wind's strength within the gale category. Surface friction also causes winds to blow more inward into low-pressure areas. [122], Wind also limits tree growth. When the temperature onshore cools below the temperature offshore, the pressure over the water will be lower than that of the land, establishing a land breeze, as long as an onshore wind is not strong enough to oppose it. [95] The velocity of surface wind is generally the primary factor governing the direction of flight operations at an airport, and airfield runways are aligned to account for the common wind direction(s) of the local area. Modern commercial wind turbines produce electricity by using rotational energy to drive an electrical generator. The direction from which a movement of air comes: The wind is north-northwest. These objects will produce sound if they touch each other. [107] Loess is a homogeneous, typically nonstratified, porous, friable, slightly coherent, often calcareous, fine-grained, silty, pale yellow or buff, windblown (Aeolian) sediment. Air, usually poetical, applies to a very gentle motion of the air. [137] Increases in wind above 15 kilometers per hour (9.3 mph) signals glaucous gulls to increase their foraging and aerial attacks on thick-billed murres.[138]. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can dominate local winds. Wind power is a popular sustainable, renewable source of power that has a much smaller impact on the environment compared to burning fossil fuels. If the wind is blowing harder, it may produce howling sounds of varying frequencies. [146] United States wildfire operations revolve around a 24-hour fire day that begins at 10:00 a.m. because of the predictable increase in intensity resulting from the daytime warmth.[147]. The wind is a clean, free, and readily available renewable energy source. Double Play Plus & WIND VISION μόνο €32/μήνα. Note: [134], Pikas use a wall of pebbles to store dry plants and grasses for the winter in order to protect the food from being blown away. [130] Flying insects, a subset of arthropods, are swept along by the prevailing winds,[131] while birds follow their own course taking advantage of wind conditions, in order to either fly or glide. Wind power is considered a renewable energy source. … [51], If there is a pass in the mountain range, winds will rush through the pass with considerable speed because of the Bernoulli principle that describes an inverse relationship between speed and pressure. When dust from the Sahara moving around the southern periphery of the ridge within the belt of trade winds moves over land, rainfall is suppressed and the sky changes from a blue to a white appearance, which leads to an increase in red sunsets. The Saffir–Simpson scale and Enhanced Fujita scale were designed to help estimate wind speed from the damage caused by high winds related to tropical cyclones and tornadoes, and vice versa.[143][22]. In Europe, similar winds are known as the Bora, Tramontane, and Mistral. A new theory on how water vapor condensation influences atmospheric pressure and dynamics", Federal Meteorological Handbook No. A squall is an increase of the wind speed above a certain threshold, which lasts for a minute or more. The solar wind is quite different from a terrestrial wind, in that its origin is the sun, and it is composed of charged particles that have escaped the sun's atmosphere. Wildfire intensity increases during daytime hours. The pilot must anticipate the wind gradient and use a higher approach speed to compensate for it.[104]. [82] Stribog is the name of the Slavic god of winds, sky and air. Its presence negatively impacts air quality by adding to the count of airborne particulates. There are two main effects. First, wind causes small particles to be lifted and therefore moved to another region. The term was first used in English in India, Bangladesh, Pakistan, and neighboring countries to refer to the big seasonal winds blowing from the Indian Ocean and Arabian Sea in the southwest bringing heavy rainfall to the area. [113] Dust events have been linked to a decline in the health of coral reefs across the Caribbean and Florida, primarily since the 1970s. [149] Such a process over geologic time causes water-rich planets such as the Earth to evolve into planets like Venus. In outer space, solar wind is the movement of gases or charged particles from the Sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. The energy that drives wind originates with the sun, which heats the Earth unevenly, creating warm spots and cool spots. Historically, wind power in the form of windmills has been used for centuries for such tasks as grinding grain and pumping water. [29] The trade winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere. Second, these suspended particles may impact on solid objects causing erosion by abrasion (ecological succession). [168], Theoretical power captured by a wind turbine, CS1 maint: multiple names: authors list (. [121] Reliance upon wind dispersal is common among many weedy or ruderal species. The wind is strong around skyscrapers. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane. As the glider descends through the wind gradient on final approach to landing, airspeed decreases while sink rate increases, and there is insufficient time to accelerate prior to ground contact. The geostrophic wind component is the result of the balance between Coriolis force and pressure gradient force. This effort is of importance in the Gulf of Maine, where surface temperatures peaked this past summer and have been warming faster than … An example is the formation of sand dunes, on a beach or in a desert. wind phrase. Wind, air, zephyr, breeze, blast, gust refer to a quantity of air set in motion naturally. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free! These were vertical-axle windmills, which had long vertical driveshafts with rectangle shaped blades. [60] Although wind produced only about 1.5% of worldwide electricity use in 2009,[60] it is growing rapidly, having doubled in the three years between 2005 and 2008. Color-coded maps are prepared for a particular area are described as, for example, "mean annual power density at 50 meters". [150] Additionally, planets with hotter lower atmospheres could accelerate the loss rate of hydrogen. Winds play a significant role in determining and controlling climate and weather. 'All Intensive Purposes' or 'All Intents and Purposes'? [63], Wind shear, sometimes referred to as wind gradient, is a difference in wind speed and direction over a relatively short distance in the Earth's atmosphere. [117] Spring storm systems moving across the eastern Mediterranean Sea cause dust to carry across Egypt and the Arabian peninsula, which are locally known as Khamsin.

King Cole Island Beaches Yarn, Hawaiian Blue Eyes Evolvulus, Cabbage Noodles Recipe, What Does It Mean When A Deer Bows To You, Dark Souls How To Get Past Archers, Bowers Bitty Suppressor, Are Dyna-glo Grills Made In Usa,
