So why hasnt the Bureau of Meteorology officially declared La Niña yet. In many locations especially in the tropics La Niña or cold episodes produces roughly the opposite climate variations from El Niño.

This weather increases the risk of wildfires in Florida and dryness in the North American plains.

In La Niña the jet stream shifts northward. Storms forecast across central and east Australia as La Niña weather event declaration expected. El Niño criteria.

It also can mean wetter conditions for northern Australia Indonesia and the Philippines drier conditions for. In this pattern strong winds blow warm water at the oceans surface from South America to Indonesia. That can lead to warm and dry conditions in the Southern United States and cooler wetter weather in parts of the North especially the Pacific.

La Ninas increase the potential for more storms and wet weather across particularly eastern Australia. And places like the southwestern United States can be very dry. Both El Niño and La Niña impact global and US.

La Niña features unusually cold weather in the Northwest and to a lesser extent northern California the northern Intermountain West and the north-central states.

This event is referred to a double-dip La Niña because similar conditions formed last year too. Warm ocean water and clouds move west during a La Niña. It has an 87 percent chance of lingering until February 2022 said NOAA in a statement.

This means that places like Indonesia and Australia can get much more rain than usual. El Niño is a series of weather patterns that occur when temperatures along the South American west coast rise due to a lack of trade winds that usually drive the warm equatorial waters towards the Southeast Asian coast and cause an upwelling of cold water in. Australias most significant driver of weather patterns La Niña is now active for a second consecutive year and will fuel weather systems with moisture for up to six months senior.

Cold La Nina is returning for Winter 20212022 with a La Nina watch now officially issued for the coming months.
