Question

Make a comparison of the climatic conditions between the “A” and “B” types of climate.

Answer 1

Af	Tropical Wet	No dry season. The driest month has at least 60 mm (2.4”) of rain. Rainfall is generally evenly distributed throughout the year. All average monthly temperatures are greater than 18°C (64°F).
Am	Tropical Monsoon	Pronounced wet season. Short dry season. There are one or more months with less than 60 mm (2.4”). All average monthly temperatures are greater than 64°F (18°C). The highest annual temperature occurs just prior to the rainy season.
Aw	Tropical Wet and Dry Climate	Winter dry season. There are more than two months with less than 60 mm (2.4”). All average monthly temperatures are greater than 18°C (64°F).
BSh	Subtropical Dry Semiarid (Steppe)	Low-latitude dry. Evaporation exceeds precipitation on average but is less than potential evaporation. The average temperature is more than 18°C (64°F).
BSk	Mid-latitude Dry Semiarid (Steppe)	Mid-latitude dry. Evaporation exceeds precipitation on average but is less than potential evaporation. The average temperature is less than 18°C (64°F).
BWh	Subtropical Dry Arid (Desert)	Low-latitude desert. Evaporation exceeds precipitation on average but is less than half potential evaporation. The average temperature is more than 18°C (64°F). Frost is absent or infrequent.
BWk	Mid-latitude Dry Arid (Desert)	Mid-latitude desert. Evaporation exceeds precipitation on average but is less than half potential evaporation. The average temperature is less than 18°C (64°F). Winter has below-freezing temperatures.
