The Am climate classification, also known as Tropical Monsoon Climate, is characterized by a short marked dry season with 1 or more months receiving less than 6 cm of precipitation, an otherwise excessively wet rainy season, and ITCZ dominance for 6 - 12 months out of the year.
The Aw climate classification, also known as Tropical Savanna climate classification, is characterized by a summer wet season, winter dry season, and ITCZ dominance for 6 months or less.
The BS climate classification, also known as semiarid climate classification, is characterized by having precipitation amounts greater than 1/2 potential evapotranspiration (POTET), but not equal to it.
The BSh climate classification, also known as the hot low-latitude steppe, is characterized by having mean annual temperatures greater than 18 degree C.
The BSk climate classification, also known as cold midlatitude steppe climate classification, is characterized by having mean annual temperatures less than 18 degree C.
The BW climate classification, also known as the arid climate classification, is characterized by having precipitation amounts less than 1/2 potential evapotranspiration (POTET).
