Special Study: An Investigation of Low-Level Winds as Related to Paradrop Operations at Dyess Air Force Base, Texas.

Abstract

Dual Theodolite Pibals were taken concurrently with Combat Control Team mean effective wind calculations. Combat Control Team errors were analyzed within selected ranges of mean effective wind and it was found that error increases significantly with increasing wind speed. Errors resulting from mean direction measurement were found to be insignificant. Similarly, aircraft positioning errors resulting from short term temporal variations were found to be insignificant when compared to speed measurement errors. Two methods of approximating mean effective winds were introduced for the purpose of providing a check against the larger CCT errors. Each method was tested for accuracy against the Dyess wind data. Of the two, a very simple estimation technique derived by the British Meteorological office fit our data very well. (Author)
