Abstract
New estimates of rainfall over the Atlantic Ocean between 30°S to 70°N have been constructed based an a technique that uses the present weather observations taken by ships. Annual and quarterly rainfall maps are presented. Between the equator and 60°N, the average annual rainfall depth is 1034 mm and the annual volume is 3.93 × 104km3. Compared to the Pacific, the Atlantic is significantly drier and has less extreme values. Maps of amplitude and phase show that most of the North Atlantic cast of 60°W experiences a inter peak rainfall. The South Atlantic experiences its peak rainfall in the Southern Hemisphere summer.
