"The earth's rain belt." Pictured knowledge. v.1. 1916.
"(I)f you could get far enough away from the earth to look back on it, as we do on Saturn through a telescope, you would see a belt of clouds around it. The water of the equator, under the hot sun, is constantly sending up vapor which turns to clouds in the cooler atmosphere of the upper regions and then comes down in rain."
