596: Which one of the following is the characteristic climate of the Tropical Savannah Region?
(a) Rainfall throughout the year
(b) Rainfall in winter only
(c) An extremely short dry season
(d) A definite dry and wet season
Explanation:
Tropical savanna climate or tropical wet and dry climate is a type of climate that corresponds to the Koppen climate classification categories "Aw" and "As". Tropical savanna climates have monthly mean temperature above 18 degree C in every month of the year and typically a pronounced dry season, with the driest month having precipitation less than 60 mm and also less than (100 - [total annual precipitation {mm}/ 25]. This latter fact is in direct contrast to a tropical monsoon climate, whose driest month sees less than (100 - [total annual precipitation {mm}/25]). In essence, a tropical savanna climate tends to either see less rainfall than a tropical monsoon climate or have more pronounced dry seasons than a tropical monsoon climate.
