El Niño/La Niña

Warming in recent decades, coupled with natural climate variations, has intensified the summer monsoon system across Asia, West Africa, and North America, according to a recent paper in PNAS.

Predictions of the effects of El Niño events on U.S. winter weather could become a lot more accurate using the results of a new study, according to the authors of the article published in Journal of Climate.

Temperatures during late November and early December were more than 2 degrees F above average in Arizona and New Mexico, according to the December Climate Outlook from CLIMAS. In fact, in many parts of eastern New Mexico, temperatures were as high as 6 degrees F above average.

A once-promising winter forecast for an El Niño-and the wet conditions it often brings to the Southwest-has dissipated. Now, it appears a neutral phase of the El Niño-Southern Oscillation, or ENSO, is moving in, diminishing chances for copious winter rain and snow in the region.

Warm temperatures and dry conditions prevailed across Arizona and New Mexico last month, according to the November Southwest Climate Outlook from CLIMAS.

Warmer-than-average temperatures have persisted in Arizona and New Mexico over the past month, with temperatures 2 to 4 degrees F above average, according to the latest Climate Outlook from CLIMAS.

Conditions in the tropical Pacific may help predict tornado outbreaks in the U.S., according to a new study published in the Journal of Climate.

September marked the 16^th consecutive month with above-average temperatures in the contiguous U.S., according to the latest State of the Climate report from NOAA.

Temperatures in Arizona cooled off this month as monsoon rainfall brought relief to the state, according to the newest Climate Outlook from CLIMAS. New Mexico, however, experienced above-average temperatures as high pressure limited monsoon precipitation across the state.

Temperatures across the U.S. were 1.6 degrees F above average in August, according to the latest State of the Climate from NOAA. Every state in the Southwest except Texas saw temperatures among their ten warmest, with Nevada tying its previous warmest August on record set in 1934.
