The relationship between El Niño and California rainfall has been described as "fragile", as only the "persistent El Niño" leads to consistently higher rainfall in the state, while the other flavors of ENSO have mixed effects at best. [14] Historically, El Niño was not understood to affect U.S. weather patterns until Christensen et al. (1981 ...
El Nino Reshapes the Weather The third state is El Niño, which occurs when sea surface temperatures in the tropical Pacific rise to above-normal levels for an extended period of time.
The effects of El Niño on rainfall in southern Africa differ between the summer and winter rainfall areas. Winter rainfall areas tend to get higher rainfall than normal and summer rainfall areas tend to get less rain. The effect on the summer rainfall areas is stronger and has led to severe drought in strong El Niño events. [174] [175]

Tropics During El Nino Wind shear makes it difficult for tropical cyclones to have a vertically aligned center, which prevents them from strengthening. Kottlowski explained that this is similar to ...
El Niño is a natural climate event caused by the Southern Oscillation, popularly known as El Niño or also in meteorological circles as El Niño-Southern Oscillation or ENSO, [6] through which global warming of the eastern equatorial Pacific Ocean results in the development of unusually warm waters between the coast of South America and the ...
El Niño patterns generally affect winters more than summers in the U.S. According to NOAA, a typical El Niño winter would produce a warmer, dryer winter season for most states in the mid ...
The first three of these events were weaker, while the 2009-10 event was a strong El Niño, but had shorter effects than the 1997–98 event. [ 9 ] [ 11 ] After the 2010–12 La Niña event had ended, near-neutral conditions persisted over the Pacific Ocean with no La Niña or El Niño events occurring. [ 12 ]
