In the semi-arid Horn of Africa, rain comes in two seasons: the “short rains” of October-December and the “long rains” of March-June. In late 2010 and early 2011, both rainy seasons brought scant rain to the region, which led devastating drought across several countries in 2011. In Somalia, the drought escalated to famine.
In early 2010, water temperatures in the eastern tropical Pacific were warmer than average, but a summertime reversal cooled the region off over the rest of the year.
Two natural climate patterns, the Arctic Oscillation and the El Niño-Southern Oscillation, had strong influences on the patterns of unusually warm and unusually cool spots worldwide in early and late 2010.
