climatic zone
From Glossary of Meteorology
A belt of the earth's surface within which the climate is generally homogeneous in some respect; an elemental region of a simple climatic classification, for example, a zone defined by the latitudinal distribution of the climatic elements.
The expressions polar, temperate, subtropical, tropical, and equatorial climate are used to indicate the climatic zones that succeed each other from the pole to the equator.
