Thermal equator

The heat equator, and thermal equator, connecting the points with the highest mean annual temperature on the earth together, usually in the form of isotherms. Strictly speaking, there is no coherent heat equator, but only a different broad zone within which lie the highest annual average. This zone is mostly north of the Earth's equator and has an average temperature of 26 ° C to 28 ° C on. The reason why the heat equator is not a circle but an irregular line or zone is to look in the height differences and the unequal distribution of land and sea.
