A study of the relationship of the displacement of cyclone to various aspects of the upper air flow

Abstract

The initial purpose for this research was to examine quantitatively the effect of "thermal steering" as applied to constant pressure and differential analysis. This investigation was later expanded to a study of the correlation between the displacement of cyclones and (1) the thermal wind, (2) the geostrophic wind, and (3) the gradient wind. Since an integrated effect of the atmospheric winds was desired, the combined influence of the thermal wind for two layers and of the geostrophic and gradient wind for three levels was studied in order to add to the facts already known about the steering effects of individual layers or levels.
