Abstract: Four numerical models are described for predicting mesoscale winds aloft for a 6 h period. These models are all tested statistically against persistence as the control forecast and against predictions made by operational ...

Abstract: The power spectrum of the wind is estimated from independent wind measurements taken at an altitude of 1,500 ft above the ground in the frequency band from 0.0625 to 1.5 cycles hr?1. Wind data were obtained simultaneously ...
