Meteorologists are certain: a La Niña winter is imminent.

Does the weather phenomenon have consequences for winter in Germany?

Are we threatened with a cold shock?

Munich - The first forecasts for winter 2021/22 in Germany are probably very exciting, especially for December.

Does winter bring snow and Siberian cold?

In view of the rising electricity and gas prices, the weather outlook this year is probably more than interesting for many people.

On top of that, a so-called La Niña winter is imminent.

Does the phenomenon affect the weather in Europe or even Germany?

La Niña - Weather phenomenon Indicates record winters

"She's baaaaaaaaack!" (In German: She is back) - headlines the US weather service NOAA over a graphic about La Niña on Instagram. An animated computer model shows how the water surface temperature in the tropical Pacific has been cooling for months, and above average. A clear indication for the researchers: The La Niña weather phenomenon is active again. The US weather experts now reckon that there is an 87 percent probability that it will persist throughout the winter. La Niña (Spanish for “the girl”) occurs every two to five years. The phenomenon upsets the weather and often leads to an increase in rain, snowfall and storms in different regions of the world. La Niña is the opposite climate anomaly to El Niño,the opponent is much more feared because of its heat and drought.

La Niña mainly ensures cooler temperatures around the equator.

The trade wind from South America towards the equator blows stronger than usual and pushes the warm surface water further west towards Australia and Southeast Asia.

The normal atmospheric circulation in the tropical Pacific is strengthened and cooled.

A striking tongue of cold water forms along the equator.

La Niña causes freak weather in certain regions

"We have already seen a likely effect of La Niña this year - a more active hurricane season in the Atlantic with almost twice as many storms as the previous average," reads a NOAA ENSO blog.

The blog deals with the predictions and observations of El Niño and La Niña and their effects, especially with a view to the USA.

ENSO stands for El Niño Southern Oscillation and is also the indicator for the weather phenomenon.

If this value falls below 0, the La Niña gets going.

At the beginning of November, this value is -1.0.

Winter in Germany?

Does La Niña have an effect on our weather?

According to the current state of science, the regions immediately bordering the Pacific are primarily affected by the La Niña weather phenomenon. But will La Niña really bring Europe and Germany a record winter? The effects are very controversial and so far little researched. The processes are complex. La Niña was already active last winter. The winter brought a lot of snow in Germany, but in the end the temperatures were rather average. Experts doubt a connection with La Niña.

"There is absolutely no scientific evidence that La Niña has an impact on our winter weather," emphasizes meteorologist Dominik Jung when asked by

Merkur.de

*. There are no statistics to prove it. The weather expert definitely does not want to speak of a “winter of the century”. "Nobody has to be afraid that heating costs will explode," says Jung. That could be disappointing for snow fans right now. And: “White Christmas” can hardly be reliably predicted at this point in time.

In 2010 there was a snowy and cold winter in Central Europe.

In any case, the meteorologist does not want to attribute this to La Niña.

Of course there could be deadlocked weather conditions that could lead to a cold spell in Germany, but these are not related to the La Niña weather phenomenon.

"Cold winter and La Niña - that is pulled by the hair," says Andreas Friedrich, spokesman for the German Weather Service (DWD) in an interview with

Merkur.de

*.

"As far as I know, there are no significant effects of La Niña on Central Europe and thus also on Germany." The phenomenon has an impact on regions in South America, Africa and Australia.

In short: It is pure speculation to link a winter forecast in Germany with a La Niña event.

A connection between La Niña or El Nino and the weather in Europe has already been the subject of science, reports the weather

The result: the analyzes do not show a clear trend.
