The last times we’ve had triple La Nina winters were stretches from the 1973-74 winter through the 1975-76 winter and then the 1998 to 1999 winter through the 2000-2001 winter.
El Niño and La Niña affect the global climate and disrupt normal weather patterns, which as a result can lead to intense storms in some places and droughts in others. [6] [7] El Niño events cause short-term (approximately 1 year in length) spikes in global average surface temperature while La Niña events cause short term surface cooling. [8]
On October 20, 2011, the National Oceanic and Atmospheric Administration's Climate Prediction Center issued its U.S. Winter Outlook. The outlook expected the present La Niña to persist and intensify into the winter, resulting in drier than normal conditions in the drought-stricken states of New Mexico, Oklahoma, Texas, and parts of adjacent states.
La Niña conditions typically span about 9 to 12 months, but can go as long as two years, according to the National Oceanic Atmospheric Administration. Ullrich said the current episode is a record ...
On October 20, 2016, the National Oceanic and Atmospheric Administration's Climate Prediction Center issued its U.S. Winter Outlook. A La Niña was expected to influence winter conditions, and the CPC noted that such conditions were likely to either develop in the late fall or early winter.
