Global ocean currents explain why Northern Hemisphere is the soggier one
Description: A quick glance at a world precipitation map shows that most tropical rain falls in the Northern Hemisphere. The Palmyra Atoll, at 6 degrees north, gets 175 inches of rain a year, while an equal distance on the opposite side of the equator gets only 45 inches. Scientists long believed that this was a quirk of the Earth's geometry. But a new study shows that the pattern arises from ocean currents originating from the poles, thousands of miles away.
