5203 |a"There are a number of previous studies on the errors in upper level winds. A paper by Major Elsaesser (1) provides a valuable summary of a number of previous studies and draws a number of conclusions as to the relative value of upper wind forecasts obtained using persistence, climatology and conventional techniques for various periods. An attempt is made in this study to verify his conclusions regarding the relative value of conventional versus persistence forecasts for 12 and 24 hours, but no comparison is made with climatological forecasts. Some of Elsaesser's paper was based on previous work discussed by Sutcliffe and Sawyer in 1953 (2)"--Abstract.
