Wind speed on the Beaufort scale is based on the empirical relationship: [6] v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.
A wind atlas contains data on the wind speed and wind direction in a region. [1] These data include maps , but also time series or frequency distributions . A climatological wind atlas covers hourly averages at a standard height (10 meters) over even longer periods (30 years) but depending on the application there are variations in averaging ...
Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes. Maps using isotherms show temperature gradients, [2] which can help locate weather fronts. Isotach maps, analyzing lines of equal wind speed, [3] on a constant pressure surface of 300 or 250 hPa show where the jet stream is located.
A wind speed of 15 mph and temperature of 15 degrees can make it feel like zero degrees, for instance. Wind chill values near minus 19 degrees mean frostbite is possible within 30 minutes.
The storm is expected to continue weakening as it travels inland. As of 11 p.m. ET Wednesday, Francine's center was about 35 miles northwest of New Orleans, the hurricane center said.
Screenshot of the Global Wind Atlas website (version 2.2) The Global Wind Atlas is a web-based application developed to help policymakers and investors identify potential high-wind areas for wind power generation virtually anywhere in the world, and perform preliminary calculations. It provides free access to data on wind power density and wind ...
Maps show the areas impacted by storm surge, rainfall levels and more as Helene, once a major hurricane and now a tropical storm, moves inland from Florida's Gulf Coast over Georgia.
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...
