Analyses of 20 Major Snowstorms: 1955–1985

As noted throughout this monograph, the evolution of the surface and tropospheric conditions prior to and during the snowstorms cannot be generalized because of the case-to-case variability that characterizes these storms. Palmén and Newton (1969, p. 273) emphasize this problem by stating: “Cyclonic disturbances appear in such diverse forms that it is impossible to give a description that is uniformly applicable to all cases.” Detailed examinations of one or two cases, although they can provide many important insights, have limited applicability in other situations with only superficial similarity. Problems with compositing antecedent conditions for East Coast storms have also been cited (Brandes and Spar 1971). Therefore, a set of conventional map analyses is presented in this chapter for each of the 20 storms to describe the unique aspects of each event as well as the similarities to the other cases.
