El Niño, the equivalent of El Niño, is characterized by normal sea surface temperatures in the Pacific Ocean near the equator – as a result of changing wind patterns in the atmosphere.
La Nina’s arrival could affect weather around the world, possibly causing more frequent and stronger storms for the last few months of Atlantic hurricanes. It can also mean wetter conditions for northern Australia, Indonesia and the Philippines, drier conditions for western South America, and cooler conditions for western Africa.
La Niña weakens the winds between the ocean surface and the upper levels of the atmosphere, which allows the storm to rise easily. It also affects the state of the jet stream over North America, which can affect the track and severity of winter storms. It goes for wet and cooler winters along the Pacific Northwest and in areas currently experiencing major wildfires.
La Nina and Climate Change
Although El Niño and La Niña events are regular aspects of global weather patterns, increasing global temperatures may cause changes in temperature or change their effects.
It is too early to know how climate change will affect those patterns; Research is beginning to show how a warmer climate can increase the effects of El Niño and La Niña.
Outside of any impact on the storm, climate change may mean that some old temperature patterns associated with El Niño and La Niña no longer apply.
Miller said, “2020 is already trending as one of the top two hottest years on record. Perhaps a cooling effect from an emerging La Nina would put it out of the top spot, but possibly still in the top 3. Will be less than, ”Miller said.
“The top spots on the hottest years list were reserved for the strong El Niño years, but human influences have long overwhelmed the planet’s natural temperature regulators.”
