wind & willow dip mix

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. 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. [121] Reliance upon wind dispersal is common among many weedy or ruderal species. [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. Wind power, form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power. [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]. These static maps illustrate multiyear average wind speeds at various heights derived from NREL's WIND Toolkit. [120] The classic examples of these dispersal mechanisms include dandelions (Taraxacum spp., Asteraceae), which have a feathery pappus attached to their seeds and can be dispersed long distances, and maples (Acer (genus) spp., Sapindaceae), which have winged seeds and flutter to the ground. Cassini–Huygens data indicated peak easterly winds of 375 meters per second (840 mph). Wind occurs because of … Sustained wind speeds are reported globally at a 10 meters (33 ft) height and are averaged over a 10‑minute time frame. Many deserts, from the rainless Atacama of South America to the arid Kalahari of Africa, are part of the horse latitudes. The Calima carries dust on southeast winds into the Canary islands. Moving air, especially a natural and perceptible movement of air parallel to or along the ground. [30] They are strongest in the winter when the pressure is lower over the poles, and weakest during the summer and when pressures are higher over the poles.[39]. wind:: noun A single turn, twist, or curve. [62] In 2011 wind energy was also used to power the longest journey in a wind-powered car which travelled a distance of 5,000 km (3,100 miles) from Perth to Melbourne in Australia. To find the mass of the packet passing through an area A perpendicular its velocity (which could be the rotor area of a turbine), we multiply its volume after time t has passed with the air density ρ, which gives us m = A v t ρ. High winds can blow objects around and pose a significant threat to your safety. 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. In competition on the wind energy market, one thing above all counts: lowest generation costs – Cost of Energy (CoE). 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. [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. 6.9mph, SW. 11.4mphE Seattle. [58] Once winds exceed 135 knots (250 km/h), homes completely collapse, and significant damage is done to larger buildings. The pilot must adjust the airspeed to deal with the effect of the gradient. [61]Wind power has expanded quickly, its share of worldwide electricity usage at the end of 2014 was 3.1%. [13] India typically reports winds over a 3‑minute average. [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. [122], Wind also limits tree growth. Wind River Studio The first cloud-native platform for the development, deployment, operations, and servicing of mission-critical intelligent edge systems that require security, safety, and … Color-coded maps are prepared for a particular area are described as, for example, "mean annual power density at 50 meters". Strong winds of intermediate duration (around one minute) are termed squalls. An example is the formation of sand dunes, on a beach or in a desert. The Wind has some less strong moments, I would not say weak, not a all; and in light of the conditions under which it was recorded, the artist fighting tooth and nail to complete the work til the end, this is a strong and fitting tribute to a rock & … [135] Cockroaches use slight winds that precede the attacks of potential predators, such as toads, to survive their encounters. Areas of wind shear caused by various weather phenomena can lead to dangerous situations for aircraft. 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%. [149] Such a process over geologic time causes water-rich planets such as the Earth to evolve into planets like Venus. The cooler air above the sea, now with higher sea level pressure, flows inland into the lower pressure, creating a cooler breeze near the coast. Air swallowed along with a feed becomes compressed by PERISTALSIS and may cause COLIC and much crying. 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. Accessed 18 Feb. 2021. Wind is a 1992 film directed by Carroll Ballard and starring Matthew Modine, Jennifer Grey and Cliff Robertson. Note: The publication dates listed below don't necessarily reflect the publication dates of the data therein. Winds play a significant role in determining and controlling climate and weather. How to use windup in a sentence. “Wind.” Merriam-Webster.com Dictionary, Merriam-Webster, https://www.merriam-webster.com/dictionary/wind. Kansas Wind Energy Project, Affiliated Atlantic & Western Group Inc, 5250 W 94th Terrace, Prairie Village, Kansas 66207, Regional Specialized Meteorological Centers, "Where do winds come from? [82] Stribog is the name of the Slavic god of winds, sky and air. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane. Wind powers the voyages of sailing ships across Earth's oceans. This barrier jet can increase the low-level wind by 45%. High winds are known to cause damage, depending upon the magnitude of their velocity and pressure differential. [40] These western ocean currents transport warm, sub-tropical water polewards toward the polar regions. Easterly winds, on average, dominate the flow pattern across the poles, westerly winds blow across the mid-latitudes of the earth, polewards of the subtropical ridge, while easterlies again dominate the tropics. Under appropriate climatic conditions, areas with loess are among the most agriculturally productive in the world. He is said to be the ancestor (grandfather) of the winds of the eight directions. Erosion can be the result of material movement by the wind. Windfinder spezializes in wind and weather forecasts for kitesurfers, windsurfer, surfers, … [80] Fūjin is the Japanese wind god and is one of the eldest Shinto gods. [119], Wind dispersal of seeds, or anemochory, is one of the more primitive means of dispersal. Using a mechanical sandblaster in a laboratory setting, scientists affiliated with the Agricultural Research Service studied the effects of windblown sand abrasion on cotton seedlings. Wind pressures are positive on the windward side of a structure and negative on the leeward side. Because of the size of the full WIND Toolkit, only the following data subsets are available for user access and download. [109] Loess tends to develop into highly rich soils. When wind gusts are at a similar frequency to the swaying of the bridge, the bridge can be destroyed more easily, such as what occurred with the Tacoma Narrows Bridge in 1940. The solar wind creates the Heliosphere, a vast bubble in the interstellar medium surrounding the Solar System. 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. In Europe downwind of the Alps, they are known as foehn. [7] Weather vanes pivot to indicate the direction of the wind. Roofs severely stripped; mobile homes overturned or badly damaged; loss of exterior doors; windows and other glass broken. [114] Similar dust plumes originate in the Gobi Desert, which combined with pollutants, spread large distances downwind, or eastward, into North America. A brief treatment of winds follows. In arid climates, the main source of erosion is wind. [110] Loess deposits are geologically unstable by nature, and will erode very readily. [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". [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. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere. Note: An important constraint on wind dispersal is the need for abundant seed production to maximize the likelihood of a seed landing in a site suitable for germination. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free! [51] Cool winds accelerating through mountain gaps have been given regional names. Infrequent wind gusts can cause poorly designed suspension bridges to sway. Strong-framed, well-built houses leveled off foundations and swept away; steel-reinforced concrete structures are critically damaged; tall buildings collapse or have severe structural deformations; cars, trucks, and trains can be thrown approximately 1 mile (1.6 km). Wind is the flow of gases on a large scale. Winds of this strength due to downsloped winds off terrain have been known to shatter windows and sandblast paint from cars. 'Nip it in the butt' or 'Nip it in the bud'. 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. When high winds knock down or uproot trees, the process is known as windthrow. 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. Define wind. Wind energy is the kinetic energy of the air in motion. Examples of these parts are balconies, ventilation openings, roof openings or cables. In Europe, similar winds are known as the Bora, Tramontane, and Mistral. Learn more. [33] Its poleward progression is accelerated by the development of a heat low over the Asian, African, and North American continents during May through July, and over Australia in December. [16] Alternatively, movement of the parent weather balloon position can be tracked from the ground visually using theodolites. b. 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. Chiudendo questo banner o proseguendo nella navigazione acconsenti all’utilizzo dei cookies . If an offshore wind of 8 knots (15 km/h) exists, the sea breeze is not likely to develop. [57] In California, downslope winds are funneled through mountain passes, which intensify their effect, and examples include the Santa Ana and sundowner winds. This may be caused by the wind blowing over cavities, or by vortices created in the air downstream of an object. Directed by Carroll Ballard. 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. 'All Intensive Purposes' or 'All Intents and Purposes'? In Central America, examples include the Papagayo wind, the Panama wind, and the Tehuano wind. Vayu is the Hindu God of Wind. [4] The ageostrophic wind component is the difference between actual and geostrophic wind, which is responsible for air "filling up" cyclones over time. High winds scour away thin soils through erosion,[123] as well as damage limbs and twigs. Its presence negatively impacts air quality by adding to the count of airborne particulates. High winds were forecast. [108] It generally occurs as a widespread blanket deposit that covers areas of hundreds of square kilometers and tens of meters thick. [142] Hurricane-force winds cause substantial damage to mobile homes, and begin to structurally damage homes with foundations. [8] At airports, windsocks indicate wind direction, and can also be used to estimate wind speed by the angle of hang. [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. These sets are tailored to the needs of common applications. A relation between the input and output wind velocity must be considered. Understanding the risks can help you prepare for these events. When the wind blows, the wind turbine's blades spin clockwise, capturing energy of the wind. 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. On the surface of the Earth, wind consists of the bulk movement of air. [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. [18] There are general terms that differentiate winds of different average speeds such as a breeze, a gale, a storm, or a hurricane. Weather radar, wind and waves forecast for kiters, surfers, paragliders, pilots, sailors and anyone else. These particles are able to escape the sun's gravity, in part because of the high temperature of the corona,[152] but also because of high kinetic energy that particles gain through a process that is not well understood. Office of the Federal Coordinator for Meteorology. What is the formula for the wind chill script? They may be used in electronic and printed publications with proper citation. Historically, the Beaufort wind force scale (created by Beaufort) provides an empirical description of wind speed based on observed sea conditions. These objects will produce sound if they touch each other. Jagged terrain combines to produce unpredictable flow patterns and turbulence, such as rotors, which can be topped by lenticular clouds. [150] Additionally, planets with hotter lower atmospheres could accelerate the loss rate of hydrogen. Directly under the subtropical ridge are the doldrums, or horse latitudes, where winds are lighter. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Many of the Earth's deserts lie near the average latitude of the subtropical ridge, where descent reduces the relative humidity of the air mass. [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. [113] Dust events have been linked to a decline in the health of coral reefs across the Caribbean and Florida, primarily since the 1970s. On the surface of the Earth, wind consists of the bulk movement of air. The kinetic energy of a packet of air of mass m with velocity v is given by ½ m v2. When winds become strong, trees and human-made structures are damaged or destroyed. [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]. [103] When landing, wind shear is also a hazard, particularly when the winds are strong. [81] In Norse mythology, Njörðr is the god of the wind. 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. When large-scale winds are calm, the strength of the sea breeze is directly proportional to the temperature difference between the landmass and the sea. During strong thunderstorms, straight line wind speeds can exceed 100 mph. [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.
