subtropics

n. regions bordering the tropics, regions north of the tropic of Cancer or south of the tropic of Capricorn

The subtropics are the zones of the Earth immediately north and south of the tropic zone, which is bounded by the Tropic of Cancer and the Tropic of Capricorn, at latitude 23.5 ° north and south. The term 'subtropics' describes the climatic region found adjacent to the tropics, usually adjacent to either the north or south pole latitudinal. However, subtropical zones can exist both north and south of many temperate zones, and so the temperate zones can only be distinguished from subtropical based on winter temperatures.
