1. Explain the basic concept of the Koppen climate classification system.
Koppen climate classification system classifies climates based on observable features such as
temperature, precipitation and wind.
2. In the Koppen climate classification letter code system, what information is given by the
first letter, the second letter, and the third letter?
The first letter designates the major climate group, the second letter usually describes
precipitation patterns, and the third letter describes temperature patterns.
3. Briefly describe the major climate groups of the modified Koppen climate classification
system: A, B, C, D, E, and H.
Tropical Humid Climates (Group A):
They are the only truly winterless climates of the world. Latitudinal location molds the
fundamental character of the Zone A climates. They dominate the equatorial regions, extending
to beyond the 25 degree parallel in some windward coastal lowlands; otherwise, they occur on a
belt between 15 to 20 degrees of equator, interrupted only be some mountain or small regions of
Dry Climates (group B)
They cover more land area than any other climatic zoneL about 30 percent of Earth’s
land surface. They are caused by more of a lack of air uplift rather than lack of moisture in air. In
subtropical latitudes, thermodynamic subsidence is widespread, which suppresses vertical
Mid Midlatitude Climates (Group C)
They occupy the equatorward margin of the middle latitudes, occasionally extending into
the subtropics and being elongated poleward in some western coastal areas. They experience
long and usually hot summers, short and relatively mild winters. T...
