The thermal climates represent major latitudinal climatic zones. They were obtained through classifying monthly temperatures
corrected to sea level (with an assumed lapse rate: 0.55°C/100m). The latitudinal thermal climates distinguished in global
AEZ are the following: tropics, subtropics with summer rainfall, subtropics with winter rainfall, temperate, boreal and polar/arctic.
The temperate and boreal belts have been further subdivided according to continentality into three classes, namely: oceanic,
sub-continental and continental.
