What climate zone is typically hot and humid with a lot of rainfall?

The tropical climate zone is characterized by high temperatures and significant levels of humidity and rainfall throughout the year. This climate is typically found near the equator and is marked by a warm temperature average, often exceeding 20 degrees Celsius (68 degrees Fahrenheit) year-round. The abundant rainfall, primarily due to convectional activities and the Intertropical Convergence Zone (ITCZ), supports lush vegetation and biodiversity common in tropical rainforests.

In contrast, the temperate climate zone experiences more variable temperatures, with distinct seasons that include colder winters and warmer summers, but it does not maintain the consistently high humidity and rainfall of tropical regions. The tundra climate, found in polar areas, is characterized by cold temperatures and minimal precipitation, allowing for only limited plant growth. Lastly, the cold desert climate is typified by arid conditions and temperature extremes, with very little rainfall, making it a stark contrast to the hot and humid conditions found in tropical zones.
