Classifications of climates in the tropics

Abstract

Differences in the thermic and hygric seasonalities cause decisive distinctions between extratropical and tropical plant growth features. Around the tropics of Capricorn and Cancer noticeable seasonal cycles of temperature still occur, which are of minor importance within the megatherm inner tropics. Two classification systems offer a subdivision of the tropical climates. Compared to the frequently used (improved) Köppen-approach (Figs. 2 and 3, left), that one of Lauer is prefered here due to its clearly defined hygrothermal regimes (Fig. 3, right). Altitudinal climate belts in the tropics are presented by a general scheme (Fig. 4), while climate and vegetation profiles reflect a realistic situation alongside the neotropical Cordilleras (Fig. 5).
