La Niña has returned in the United States, but this time it is expected that they will remain weak, which forced the climate protection center to give advice. In the paper on the X federal prediction, they stated that the conditions of La Niña were present and preferred to persist to December 2025-February 2026.
“The latest weekly value of the Niño -3.4 index was -0.5 ° C, the other areas remaining at or between -0.1 ° C and -0.4 ° C (Fig. Half, “, on average, average, average, average, average, on average, on average, on average, on average, on average by 200 m equations,” (diameter from 180 ° W;
What is La Niña and how does it occur?
La Nina is a naturally occurring climatic formula that cools the surface temperatures in the middle and eastern equatorial Pacific Ocean. It occurs when parts of the central Pacific Ocean cool 1.5 degrees C below normal.
La Nina tends to bring more hurricanes in the Atlantic Basin and less in the Pacific to change changes in the speed and direction of the wind with a high atmosphere.
It is the main factor affecting American weather, especially from the end of autumn to early spring. Often this meant more rainfall – including possible snow storms.
How long will La Niña stay?
The resort said La Niña began to appear in September 2025, as shown in the expansion of below -average temperatures of the sea surfaces (SST) across the middle and eastern equator of the Pacific Ocean.
This time, La Niña is expected to persist in winter, with 55 % chances to cross the neutral conditions between January and March 2026.
“Weaker” La Niña this time? ‘With surprise’
NWS added that this predicted weakness of La Nina “should be less likely to lead to conventional winter impacts”.
“At the moment, La Niña is expected to remain weak (average average value of the Niño -3.4 index at -0.5 ° C and -0.9 ° C). The weak la niña would have less likely to lead to conventional winter impacts, although predictable signals could still affect the instructions,” he said.
Michelle L’Hureux, the main scientist in the NOAA team, who studies La Nina and El Nino, said AP that the conditions will not be too strong.
“There are three out of four chances that they will remain a weak event,” she said, adding: “The weaker event tends to have less influence on global circulation, so it is possible that they will be surprised.”
When the state of La Niña began to return, the east threw away the winds near the surface, while the winds moved from the west through the western and central Pacific. The storm activity was stronger after Indonesia than usual, but weaker near the date line.
