WW2D Plus One - an update to WW2D providing a 3D view. Punt was a fork of the .NET NASA WorldWind project, and was started by two members of the free software community who had made contributions to WorldWind. Punt was based on the code in WorldWind 1.3.2, but its initial release has features not found in WorldWind 1.3.2 or 1.3.3 (such as ...
Thus, for example, the wind forecast for Abilene (ABI) at 30,000 feet, shown above as 7603, indicates a forecast wind of 260 degrees at 103 knots (76-50=26 or 260, and speed became 100+03=103). This forecast is now made four times a day based on 0000Z, 0600Z, 1200Z, and 1800Z data (the Z stands for Zulu and indicates Coordinated Universal Time ).
The latest release of the Global Wind Atlas (3.0) was launched on October 25, 2019, featuring further methodological modeling improvements, all new raw data (based on 10 years of mesoscale time-series model simulations), data coverage spanning 200 kilometers offshore, two additional heights (data now at 10, 50, 100, 150 and 200 m above ground ...
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 ...
Sea surface roughness corresponds to wind speed. [11] Using a network of eight small satellites enables frequent observations: the mean revisit time is predicted to be 7 hours. [ 15 ] [ 16 ] The eight microsatellites orbit at an inclination of 35°, and are each capable of measuring 4 simultaneous reflections, resulting in 32 wind measurements ...
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 ...
The "global terrestrial stilling" is not affecting in the same way the whole Earth's surface across both land and ocean surfaces. Spatially, increasing wind speed trends have been reported for some regions, in particular for high-latitudes, [18] coastal [19] and for ocean surfaces where different authors [3] [20] [4] have evidenced an increased global trend of wind speed using satellite ...
Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h). [ 310 ] A DOW calculation of a subvortice of the 2013 El Reno tornado was estimated in a range of 257–336 mph (414–541 km/h) in 2024.
