The term "subtropical" refers to a climate and vegetation zone that is characterized by warm, humid summers and mild winters. This type of climate occurs in regions that are located between the Tropic of Cancer and the Tropic of Capricorn, where the sun's rays hit at a lower angle than they do closer to the equator. Subtropical climates typically experience distinct wet and dry seasons, with most of their annual rainfall occurring during the summer months. The vegetation in subtropical regions is often lush and diverse, featuring plants such as palm trees, banana plants, and bougainvillea.
