Rain patterns are changing
The crippling drought now plaguing California is due to a persistent high pressure system off of the coast that is deflecting storms away from the region . A recent study shows that these systems are much more likely to occur with human-caused climate change.
Why is rain different?
As moist air rises up through a cloud, the air cools and the water in it turns into tiny raindrops . ... In a cloud, these tiny raindrops are very light and float as the rising air pushes them up. But the higher they go, the larger and heavier they get. Eventually, they get so heavy that they fall to the Earth as rain.
Why are some places wetter than others?
How much precipitation an area receives also depends on its elevation. Higher elevations are wetter than nearby lower elevations . Ocean currents, sea surface temperatures, interior continentality, and prevailing winds also come into play when determining where precipitation falls.

The Atacama Desert in Chile is in a rain shadow created by both the Andes Mountains and weather patterns over the Pacific Ocean.
At what latitudes is air sinking?
Hadley cells, Ferrel (mid-latitude) cells, and Polar cells characterize current atmospheric dynamics. Hadley Cells are the low-latitude overturning circulations that have air rising at the equator and air sinking at roughly 30° latitude .
