An air mass frequency model is constructed to facilitate the formulation of a genetic classification of climate. The model uses Venn diagrams to distinguish three basic climatic regimes, each determined by the relative dominance of air masses: the dominant regimes, where a single air mass dominates all year; the seasonal regimes, determined by seasonally dominant air masses; and the compound regimes, with no dominant air mass. Different climates within each regime are distinguished by actual air mass types. Monthly air mass dominance is determined from actual station surface data for application of the model to world climates. This is completed by analysis of monthly data plotted on modified climographs and by the construction of a monthly air mass identification chart. The proposed system is illustrated by Australian data. [ABSTRACT FROM AUTHOR]
