Abstract: Statistical analyses of wind speeds from climatological data and from special studies of short-duration winds suggest that the distributions of the ratios of the time unit (monthly, daily, etc.) to the long-range average ...

Abstract: This paper presents a power spectrum of surface winds, developed as part of a study on flight control design. The spectrum, derived by a simple method of calculation, extends from 10?8 cps to 1 cps. Over much of this band ...
