The La Niña phenomenon returns for the third year in a row.

The meteorological system over the Pacific Ocean that could influence weather patterns around the world is expected to last until the end of the year.

it’s a For the first time this century That La Niña has returned for three years in a row, according to the World Meteorological Organization, a United Nations agency.

“It is extraordinary that there have been three consecutive years with a La Niña event,” WMO Secretary-General Petteri Taalas said in a statement.

La Niña is happening When strong winds blow warm waters on the surface of the Pacific Ocean near the coast of South America across the equator towards Indonesia and other parts of Asia and Australia.

This warms the cooler waters to the surface of the Pacific Ocean, which has wide-ranging ripple effects on the weather.

Some people will experience drier weather; Others will face more floods

The southwestern United States, as the clouds of rain are pushed out to sea, is getting drier than usual. The northwestern United States and Canada experience below-average temperatures, rain and flooding.

Australia, Indonesia and other parts of Asia also experience heavy rainfall. La Niña can cause more lightning activity in the Gulf of Mexico and along the Gulf Coast and increase the number of hurricanes and tropical cyclones, According to the National Oceanic and Atmospheric Administration.

This year, scientists also attributed the worsening drought in the Horn of Africa and the southern part of South America to La Niña.

Although the storm system will produce some colder temperatures in one part of the world, the United Nations says that warmer sea surface temperatures elsewhere will lead global forecasts in the coming months.

Climate change continues to raise global temperatures and contribute to more extreme weather events, including La Niña.

“Its cooling effect temporarily slows the rise in global temperatures – but it won’t halt or reverse the long-term warming trend,” Taalas said.

La Niña is the opposite of El Niño, as trade winds weaken over the Pacific and warm waters off the west coast of the Americas.
