Subtropics


Definition:

The subtropics (lat. sub = before; ancient Greek tropaí = tropic circles) are a climate zone between the warm temperate zone and the tropics. This corresponds to about 20 ° and 40 ° north latitude and south latitude. The average annual temperature is between 18 and 22 ° C.
There are three different climatic types within the subtropics:
Dry subtropics: year-round, arid climate with desert vegetation zone (including the Atacama Desert, Sahara) or steppe.
Winter moisture subtropics (Mediterranean climate): arid climate in summer, mild in winter and with precipitation. Often referred to as maritime climate (including Mediterranean, California).
Always moist subtropics (East Side Climate): Trade winds provide year-round rainfall. During the rainy season in summer significantly more precipitation falls (including East Asia, East Australia, East Coast of the USA).

As a rule, no temperatures in the minus range
all-season vegetation period possible (except dry subtropics)
Change of rainy season and dry season
tradewinds
Extreme weather events possible (droughts and floods)
