Detailed explanation-1: -In general, El Niño conditions lead to wetter, snowier conditions in Amarillo and cooler maximum temperatures during the winter. La Niña conditions lead to drier and warmer temperatures overall, with notable extreme cold spells.
Detailed explanation-2: -On average, strong El Nino winters have less very warm days (highs of 70 F or greater) as well as less very cold days (highs of 32 F or colder) when compared to the long-term normals.
Detailed explanation-3: -El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
Detailed explanation-4: -El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas. These changes in the Pacific Ocean and its overlying atmosphere occur in a cycle known as the El Niño–Southern Oscillation (ENSO).
