Abstract

NOAA meteorologists have put mathematical equations to work in a computer and successfully simulated many of the major features of the world's hydrologic cycle.

Starting only with equations describing atmospheric motions, the locations and heights of the continents, and sea-surface temperatures, the computer correctly located rainbelts in the tropics, areas of desert such as the Sahara and western Australia, and the watersheds of some of the world's major rivers, such as the Amazon in South America, the Congo and Nile in Africa, and the Mississippi.
