Abstract : Three forms to describe global conditions for computer analysis of the wind influence upon missile systems have been common in the past: Individual wind profiles, intra and inter-level correlation matrices, and synthetic wind profile. All three methods show one or several kinds of deficiency: Voluminous data input, data bias, unrealistic vertical relationship, complex and costly computation, or difficulty in associating probability. The above problems can be solved by the characteristic coefficient technique. The individual wind profile is described by a number of characteristic coefficients with subsequent reduction to one variable only. Three equations and a set of constants express completely the variety of global wind conditions and association with any wind probability threshold. Based upon the above tool sets of global wind models can be derived. The geographic and seasonal variation of a system of nine model groups is discussed and proves to be rational. (Author)
