Rainfall and the tropical climate dominate the tropical rain belt, which oscillates from the northern to the southern tropics over the course of the year, roughly following the solar equator. The tropical rain belt is an area of active rain that is positioned mostly around the tropics. According to the website Journey North, the reason the rain belt is situated near the tropics can be attributed to the fact that most of the sun's radiation is directed toward the equator, which is located in the middle of the tropics. This solar radiation generates large amounts of heat near the equator providing tropical regions with higher temperatures than most other regions on Earth.
