The term "subtropical" refers to regions that are located between tropical and temperate zones. These areas typically experience warm to hot summers and mild winters, with distinct seasonal changes. Subtropical climates often have high humidity and receive significant rainfall, supporting diverse ecosystems. Subtropical regions can be found on every continent, including parts of the United States, Australia, and South Africa. Common vegetation in these areas includes evergreen trees, cacti, and various types of grasses. The subtropical climate is ideal for growing certain crops, such as citrus fruits and olive trees.
