In fact, about two-thirds of all rain falls along or near the equator, and countries in those latitudes often have several months of near-daily rain followed by months of dryness as the rain band moves north and south. A band of heavy rain moves north and south of the Equator seasonally.

The most obvious pattern in the total rainfall maps is seasonal change. High rain totals are represented in dark blue, while small rainfall totals are shown in white. The rainfall maps show total monthly rainfall in millimeters from NASA’s Integrated Multi-satellitE Retrievals for GPM (IMERG) dataset. This heating is a major part of Earth's energy budget and climate. Later, when the water vapor condenses to form cloud droplets and rain, the heat is released into the atmosphere. When water evaporates from the surface and rises as vapor into the atmosphere, it carries heat from the sun-warmed surface with it. In addition to moving tremendous amounts of water through Earth’s atmosphere, rain clouds also move tremendous amounts of energy. Globally, rain is the main source of fresh water for plants and animals rainfall is essential for life across Earth’s landscapes.
