The girl could reappear before the end of 2021, just five months after the OWorld Meteorological Organization (WMO) declared finished on phenomenon, due to a forecast of temperatures above average despite the effect of cooling that produced his recent step.
The OMM estimates that there is a 40% chance that The girl -which corresponds to the large-scale cooling of surface waters in the central and eastern equatorial Pacific- reappears after its presence from August 2020 to May this year.
“But despite the La Niña phenomenon, which usually has the effect of cooling the climate, the temperatures measured on land should be higher than the average between September and November, especially in the northern hemisphere, “the organization stresses.
The impact of La Niña, which occurs every two to seven years, is felt over a large part of the planet in the form of variations in atmospheric pressure, winds and rainfall, with effects generally inverse to that of another phenomenon, El Kid.
But climate change caused by human activities influences these phenomena.
“The climate change of anthropic origin amplifies the effects of natural phenomena such as La Niña and increasingly influences our meteorological conditions, which translates especially into more intense heat and drought (and the associated risk of forest fires), as well as rainfall and record floods, “declared the secretary general of the OMM, Petteri Taalas.
“We have been tragically witnesses in recent months in almost all regions of the world. Climate change increases the severity and frequency of disasters,” he stressed, alluding to both the gigantic fires that affected the western United States and Siberia as well as Hurricane Ida, which swept through the southern United States before leaving New York and its neighboring states under water due to very heavy rainfall.
WMO said yes The girl reappears is expected to be weak, and above-average sea surface temperatures should influence air temperatures for the period September to November 2021.
According to the organization, temperatures would be above average in east-central North America, the extreme north of Asia and the Arctic, as well as in central and eastern North America. Africa and southern South America.
There is a greater chance of below-normal rainfall in many areas of southern South America.
A large part of the Mediterranean as far as the Arabian Peninsula and Central Asia, and southern central and eastern Africa would also experience below normal rainfall.
