What are the climate regions around the world? What are their characteristics?
The Köppen Climate Classification System is the most widely used system for classifying the world’s climates. Its categories are based on the annual and monthly averages of temperature and precipitation. The Köppen system recognizes five major climatic types; each type is designated by a capital letter. A – Tropical Moist Climates: all months have average temperatures above 18° Celsius. B – Dry Climates: with deficient precipitation during most of the year. C – Moist Mid-latitude Climates with Mild Winters. D – Moist Mid-Latitude Climates with Cold Winters. E – Polar Climates: with extremely cold winters and summers Tropical Moist Climates (A) Tropical moist climates extend northward and southward from the equator to about 15 to 25° of latitude. In these climates all months have average temperatures greater than 18° Celsius. Annual precipitation is greater than 1500 mm. Three minor Köppen climate types exist in the A group, and their designation is based on seasonal distribution of rai
