Causes of humid climate in Latin America

The weather in Latin America is hot and humid, because it is close to the equator, there are more updrafts and precipitation, and the climate is hot and rainy. In addition, there is a lot of rain forest transpiration in the Amazon plain, which brings a lot of precipitation. The Andes in the west blocked the warm and humid air flow in the Pacific Ocean and could not cause the deep sultry phenomenon. The Brazilian warm current in the east has the function of warming and humidifying, and this terrain has caused the hot and humid climate in Latin America.
