Windy is a Czech company providing interactive weather forecasting services worldwide. The portal was founded by Ivo Lukačovič in November 2014, [ 1 ] [ 2 ] initially focusing on wind animation. It has since expanded to include various essential meteorological parameters, such as temperature , pressure , relative humidity , cloud base, and ...
where T wc is the wind chill index, based on the Celsius temperature scale; T a is the air temperature in degrees Celsius; and v is the wind speed at 10 m (33 ft) standard anemometer height, in kilometres per hour. [11] When the temperature is −20 °C (−4 °F) and the wind speed is 5 km/h (3 mph), the wind chill index is −24.
The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a shelter such as a Stevenson screen—a standardized, well-ventilated, white-painted instrument shelter. The thermometers should be positioned 1.25–2 m above the ground.
Roaring Forties as they contract towards southern Australia (observed in September 1895). [1]The Roaring Forties are strong westerly winds that occur in the Southern Hemisphere, generally between the latitudes of 40° and 50° south. [2]
The cross-isobar angle of the diverted ageostrophic flow near the surface ranges from 10° over open water, to 30° over rough hilly terrain, and can increase to 40°-50° over land at night when the wind speed is very low. [14] After sundown the wind gradient near the surface increases, with the increasing stability. [23]
Although wind damage is rare to tropical cyclones near landmasses, there are a few factors that lead to high wind speeds. Warm water temperatures, which was seen during Hurricane Wilma when its winds rapidly strengthened to 185 mph (298 km/h) in a 24-hour period due to the presence of abnormally warm water temperatures.
Southern California Edison opened its Wind Energy Center eight miles northwest of Palm Springs in 1980 near its Devers substation, installing two wind turbine generators for testing. [11] One of these was the SWT-3 horizontal axis wind turbine generator designed by Charles Schachle and produced by the Bendix Corporation .
