Figure 1.7. Climatic regimes and climate-processes. Graphs show monthly rainfall and temperature
data reported by Strahler (1965). Scales are modified to emphasize arid regions. System boundaries are
given by dash dot-lines. Systems indicated by letter abbreviation: A - arid; SA - semiarid; S - selva;
HT - humid-temperate; P - periglacial and G - glacial (Wilson, 1968).
