According to the website, each monthly issue "contains monthly mean temperature, pressure, precipitation, vapor pressure, and sunshine for approximately 2,000 surface data collection stations worldwide and monthly mean upper air temperatures, dew point depressions, and wind velocities for approximately 500 observing sites.
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 ...
In terms of wind speed, Allen from 1980 was the strongest Atlantic tropical cyclone on record, with maximum sustained winds of 190 mph (310 km/h). For many years, it was thought that Hurricane Camille also attained this intensity, but this conclusion was changed in 2014.
GIS data from the Global Wind Atlas is available via the IRENA Global Atlas for Renewable Energy, and has been included as the core wind data in the RETScreen software. [12] It is used by governments, renewable energy developers, and academics, and has an average of 7,500 unique users per month as of October 2018.
Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h). [311] 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. [312]
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 ...
New mobile radar data shows that wind speeds in the recent Greenfield tornado passed 300 mph. Scientists say it's rare.
