Scientists know that aerosols — both natural, as from volcanoes, and human-caused, as from pollution — can change a cloud’s thickness, ability to scatter sunlight or how much rainfall it produces.

Climate change has boosted the cost of flood damage caused by heavy rainfall in the United States by $75 billion over the past three decades, accounting for about a third of total losses, Stanford University researchers say.

Days of extreme rainfall — which have doubled in the Southeast as a consequence of warming — stymie septic systems.

The heavy rainfall is related to a slow-moving cold front that will draw tropical moisture into the region, including some from Tropical Storm Eta in the Gulf of Mexico.

Total rainfall from Wednesday through Thursday should run about one to three inches.

The ancient Maya believed that the underworld of caves was home to gods that controlled rainfall and harvest bounties.

The Golden State got slammed by record-low rainfall in 2013 and remains frighteningly dry despite a few recent storms.

That state had its lowest rainfall (and its second-hottest weather) in recorded history in 2011.

And in the last two years, rainfall, which averages 34 inches annually, has fallen at about half that rate.

The nearest place with average rainfall is about 60 miles away.

The heaviest rainfall usually occurs, however, during the summer.

Rainfall typically is abundant and well-distributed throughout the year.

Thus the Gulf Stream, directly and indirectly, probably contributes more than half the rainfall about the Atlantic basin.

In general, the central parts of continents are likely to receive much less rainfall than their peripheral portions.

On this account the rainfall in countries placed under such conditions is commonly small.
