Answer: A. Koppen
Explanation:
Koppen climate classification is the main method of classifying global climates. It uses a system that measures average temperatures and rainfall across the year. It lists five different climates, namely:
A: Tropical Wet Climates with temperatures of 19 and above all year round
.
B: Dry Climates, with little rainfall all year round
.
Climates C and D are found in middle and high latitude areas and are differentiated by their winters
.
C: Mid-Latitude climates, with mild winters
.
D: Mid-Latitude climates, with cold winters
.
E: Polar Climates: these climates are defined by very cold winters and summers
.
H: Highland Climates, all highland areas with climates which are difficult to classify under the other 5 climate groups fall here.
