Wind, air, zephyr, breeze, blast, gust refer to a quantity of air set in motion naturally. 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. At night, the land cools off more quickly than the ocean because of differences in their specific heat values. [68], Sound movement through the atmosphere is affected by wind shear, which can bend the wave front, causing sounds to be heard where they normally would not, or vice versa. Its speed is 20,000,000 miles per hour (32,000,000 km/h), which is 3% of the speed of light. Wind engineering describes the study of the effects of the wind on the built environment, including buildings, bridges and other man-made objects. Our Word of the Year 'pandemic,' plus 11 more. [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. Each day, around the world, wind turbines are capturing the wind’s power and converting it to electricity. [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. Winds of this strength due to downsloped winds off terrain have been known to shatter windows and sandblast paint from cars. These were vertical-axle windmills, which had long vertical driveshafts with rectangle shaped blades. When winds are sustained at 40-50 mph, isolated wind damage is possible. 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. Windfinder specializes in wind, waves, tides and weather reports & forecasts for wind related sports like kitesurfing, windsurfing, surfing, sailing, fishing or paragliding. Ex : garçon - nm > On dira "le garçon" ou "un garçon". Historically, the Beaufort wind force scale (created by Beaufort) provides an empirical description of wind speed based on observed sea conditions. [159][160] On Jupiter, wind speeds of 100 meters per second (220 mph) are common in zonal jet streams. [136] Elk have a keen sense of smell that can detect potential upwind predators at a distance of 0.5 miles (800 m). 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. It was the first wind farm over 100MW to be built in the Dutch North Sea and comprises 36 wind turbines that produce enough renewable electricity for more than 100,000 Dutch households. The ancient Greeks also observed the seasonal change of the winds, as evidenced by the Tower of the Winds in Athens. [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". 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. wind phrase. [91] A severe storm could lead to shipwreck, and the loss of all hands. [50] Wind direction also changes because of the contour of the land. How to use wind in a sentence. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network. The movement of air causes movements of parts of natural objects, such as leaves or grass. 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. Wind erosion generally occurs in areas with little or no vegetation, often in areas where there is insufficient rainfall to support vegetation. Forecast This forecast is based on the GFS model. But how is wind energy created? [151] Other phenomena caused by the solar wind include geomagnetic storms that can knock out power grids on Earth,[154] the aurorae such as the Northern Lights,[155] and the plasma tails of comets that always point away from the sun. The solar wind creates the Heliosphere, a vast bubble in the interstellar medium surrounding the Solar System. When a high measurement frequency is needed (such as in research applications), wind can be measured by the propagation speed of ultrasound signals or by the effect of ventilation on the resistance of a heated wire. [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. Test Your Knowledge - and learn some interesting things along the way. It is commonly observed near microbursts and downbursts caused by thunderstorms,[68] weather fronts, areas of locally higher low level winds referred to as low level jets, near mountains,[69] radiation inversions that occur because of clear skies and calm winds, buildings,[70] wind turbines,[71] and sailboats. First, wind causes small particles to be lifted and therefore moved to another region. Internet 50Mbps, τηλεόραση WIND VISION με περισσότερα από 60 συνδρομητικά κανάλια & δώρο Wi-Fi Extender για κάλυψη σε κάθε γωνιά του σπιτιού! [41] The Westerlies play an important role in carrying the warm, equatorial waters and winds to the western coasts of continents,[42][43] especially in the southern hemisphere because of its vast oceanic expanse. Unlike the Westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. (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. [118] The Shamal is caused by cold fronts lifting dust into the atmosphere for days at a time across the Persian Gulf states. Intensity Observation and Forecast Errors", "National Weather Service Instruction 10-1605", National Centers for Environmental Prediction, "African Dust Called A Major Factor Affecting Southeast U.S. Air Quality", "Chapter-II Monsoon-2004: Onset, Advancement and Circulation Features", "Climatology of the Interior Columbia River Basin", National Environmental Satellite, Data, and Information Service, National Oceanographic Partnership Program, "The Physical Environment: Global scale circulation", "The Role of Mountains in the South Asian Monsoon Circulation", 10.1175/1520-0469(1975)032<1515:TROMIT>2.0.CO;2, "The influence of mesoscale orography on a coastal jet and rainband", 10.1175/1520-0493(1997)125<1465:TIOMOO>2.0.CO;2, "T-REX: Catching the Sierra's waves and rotors", "CHAPTER 8: Introduction to the Hydrosphere (e). There are also strong evolutionary constraints on this dispersal mechanism. 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. Similar to the solar wind, the planetary wind is composed of light gases that escape planetary atmospheres. [16] Alternatively, movement of the parent weather balloon position can be tracked from the ground visually using theodolites. [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. The strongest observed winds on a planet in the Solar System occur on Neptune and Saturn. Office of the Federal Coordinator for Meteorology. 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. The film is directed by Emma Tammi, written by Teresa Sutherland and stars Gerard, Ashley Zukerman, and Julia Goldani Telles. In fact, wind exists because the sun unevenly heats the surface of the Earth. Harnessing the unequaled wind resources off the coast of Maine is critical to meet the state’s climate goals of moving Maine to using 80 percent renewable energy by 2030, and 100 percent by 2050, in order to curb harmful greenhouse gas emissions. [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. [79], Kamikaze (神風) is a Japanese word, usually translated as divine wind, believed to be a gift from the gods. Wind is the flow of gases on a large scale. These winds are warm and dry. A tailwind increases takeoff distance required and decreases the climb gradient. Each full flag depicts 10 knots (19 km/h) of wind. [142] Hurricane-force winds cause substantial damage to mobile homes, and begin to structurally damage homes with foundations. [106], There are local names for winds associated with sand and dust storms. [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. [58] Once winds exceed 135 knots (250 km/h), homes completely collapse, and significant damage is done to larger buildings. SYNOP codes from weather stations and buoys. The wind is strong around skyscrapers. This is called deflation. This page was last edited on 29 November 2020, at 06:50. Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. It consists mostly of electrons and protons with energies of about 1 keV. wind noun (CURRENT OF AIR) A1 [ C or U ] a current of air moving approximately horizontally, especially one strong enough to be felt: There isn't enough wind to fly a kite. [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.
