Less than half of the rain that falls from a cloud makes it all the way to the ground – because a lot evaporates while falling or after landing in treetops.

FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some keywords to get your googling started:

Virga: an observable shaft of precipitation falling from a cloud that evaporates before reaching the ground

Rainfall interception: The fraction of rainfall that falls on leaves, branches and trunks of trees and evaporates before dripping to the ground.
