Throughout this Winter, La Nia will Remain in operation
It’s not there yet, but the influential pattern is still expected to form as the northern hemisphere heads into winter.
According to researchers at the Global Climate Prediction Center (GCP), La Nia continued to affect the Pacific until the end of November.
Sea surface temperatures at the equator in the eastern Pacific Ocean are monitored by weather forecasters for periods when they exceed or are below seasonal levels.
La Nia events are marked by sea surface temperatures below normal for around seven months, whereas El Nios are marked by sea temperatures slightly above normal for about seven consecutive months.
We’re in a neutral pattern this month, with temperatures barely varying from normal within a few tenths of a degree, meaning that neither El Niño nor La Niña are present.

The CPC said on Thursday that la Nia may form as expected, but that it will likely be weak. There is less likelihood of conventional winter impacts resulting from a weak La Nia, the experts said.
A La Nia pattern in the summer had originally been predicted, but warm ocean waters and unexpected wind shifts will likely delay its arrival for some time.
La Niña has several noticeable effects on Canadian winters. Western Canada typically experiences below-seasonal temperatures, whereas the Great Lakes and Eastern Canada can expect active storm tracks.
Can you tell me what that could mean for the upcoming season? Canada’s winter weather patterns are driven by many factors.
El Nio and La Nia are just one piece of the puzzle. Getting a declaration doesn’t matter that much to our winter forecast, according to Dr. Doug Gillham of The Weather Network.
“An event doesn’t need to be declared to have an impact on the atmosphere,” Dr. Gillham said.
According to him, this is more important to the forecast for the winter than the strength of the event.
