The La Niña phenomenon, which typically occurs every two to seven years and lasts for about a year, is currently displaying unusual behavior, according to NOAA. Forecasts suggest that La Niña will be both shorter and weaker than in previous occurrences.
NOAA reports a 59% likelihood that La Niña will persist from February to April, followed by a 60% chance of neutral conditions from March to May. Despite its weakened state this year, La Niña is expected to significantly impact global weather patterns.
La Niña can trigger various weather and climate changes across vast regions of the globe.
