"These findings suggest that weather extremes as seen during the 2020–2022 La Niña will probably occur more frequently in the near future," said Geng Tao from Ocean University of China, co-author of the study, in a news release. In Canada, La Niña winters are also typically wetter and colder, the National Oceanic and Atmospheric Administration says. The actual developer of the program is NASA. We cannot confirm if there is a free download of this software available. La Niña increases Atlantic hurricane activity and worsens western drought.

The study suggests that the slower heat recharge associated with the northward-broadened easterly wind anomalies are what ultimately enables the cold anomalies of a La Niña to persist for longer than a year.Ĭompared to single-year La Niña events, multi-year La Niña events such as the one that lasted from 2020 to 2022 create higher or cumulative risk of extreme weather events, the study notes, including droughts, wildfires, flooding and altered patterns of hurricanes, cyclones and monsoons across the Pacific and Atlantic oceans. These easterly wind anomalies are further intensified by faster warming in the equatorial eastern Pacific. "Under present-day climate conditions, a strong El Niño in the boreal winter induces a negative North Pacific Meridional Mode (NPMM)-like response in the subtropical North Pacific, producing a La Niña in the ensuing winter with meridionally extensive sea surface temperature (SST) and easterly wind anomalies," said Jia Fan, a co-author of the study from the Institute of Oceanology of the Chinese Academy of Sciences, in a news release. The study also explains the conditions underlying the projected increase. They projected an increase in frequency ranging from 19 per cent, plus or minus 11 per cent, in a low greenhouse gas emissions scenario to 33 per cent, plus or minus 13 per cent, in a high emissions scenario. reported a “significant increase" in the projected frequency of multi-year La Niña events over a 100-year period. The ENSO pattern alternates irregularly between warm El Niño and cold La Niña events, impacting global weather patterns, agriculture and ecosystems.īased on multiple climate models collected by the Coupled Model Intercomparison Project Phase 6 (CMIP6), researchers from China, Australia and the U.S. System Utilities Photo & Graphics Multimedia Games Internet & Network Mobile Phone. ![]() Get NASA World Wind alternative downloads. La Niña is the colder counterpart of El Niño, as part of the broader El Niño–Southern Oscillation (ENSO) climate pattern, which is characterized by the shifts in ocean temperatures and atmospheric conditions in the Pacific.

This weather phenomenon typically occurs approximately every three to five years and lasts one to two years, Environment and Climate Change Canada notes. La Niña refers to a period of cooler than normal waters in the eastern and central Pacific Ocean. The new numbers are “continuing that pace.The world will likely see more multi-year La Niña events due to global warming, contributing to a higher risk of extreme weather events, according to a recent study published in the scientific journal Nature. “I expected the economy to slow down in a fairly orderly way,” Atlanta Fed President Raphael Bostic said Friday. Two Fed officials say those slower employment gains suggest the labor market is coming into better balance, arguing the central bank may soon need to pivot from raising rates to thinking about how long to hold them at elevated levels. With unemployment again near record-low levels, though, wages rose more than expected. That’s also contributing to renewed confidence among consumers, which may bode well for spending and growth. Healthy job and income gains point to an economy capable of weathering any fallout from the Federal Reserve’s rapid interest-rate increases over the past year, which have come close to taming high inflation. New US jobs numbers Friday seem to add insult to injury for Team Recession as data show the labor market cooling just enough, adding more support to a possible soft landing for the world’s largest economy. ![]()
