This wind climatology is based on historical data from NOAA’s Unrestricted Mesoscale Analysis (URMA). See here. The dataset provides hourly wind speed and direction for CONUS, Alaska, Hawaii, and Puerto Rico on a horizontal grid-spacing of 2.5 km for all domains except Alaska (3 km) and Puerto Rico (1.25 km). URMA is based on the same system that provides the Real Time Mesoscale Analysis (RTMA). Both RTMA and URMA are 2DVar analysis systems that provide analyses of National Digital Forecast Database parameters. While RTMA is considered for situational awareness, URMA is considered for verification/validation. URMA also serves as a critical component in the National Blend of Models (NBM) program, as it is used for calibration and validation. URMA is a modeling system based on 2-dimensional variational analysis of surface sensible weather fields. Thus, users of this product should be aware the outputs are modeled and not direct observations.

High/Low wind months are calculated by taking the mean 10 meter wind speed for each grid point over the entire climatology (1985-2022) and ranking them. Find the 10th and 90th percentile of the point and compare it with each month and year. The result is the number of months for each year that is above/below these percentiles.

  • This climatology was produced jointly with help from the Western Regional Climate Center.
