Many dream of snow at the festival.
Experts predict it could work this year.
In addition to a white Christmas, it could also be very cold.
Usually meteorologists are reluctant to make predictions far in advance.
Because the longer the forecast, the more uncertain it is.
The weather experts make an exception every year at one point: snow.
The first cautious outlooks for winter appear as early as October.
Above all, one question arises: Will there be a white Christmas this year?
The answer depends on various factors, as reported by echo24.de *.
The winter weather in Germany is influenced by certain phenomena that occur elsewhere in the world.
The so-called polar vortex split caused a sensation in 2021 - it brought arctic cold with it in the first few months of the year.
White Christmas 2021?
"Snow bomb" according to the expert on the approach
The polar vortex forms in October and then circulates over the Arctic.
If warm and cold air meet there, the probability of division increases.
This year, too, “this could cause the polar vortex to stumble a little”, as meteorologist Corinna Borau explains at wetter.com.
Then Germany is threatened with Arctic cold again.
However, forecasts for the entire winter have so far been difficult.
But if the polar vortex actually divides again, “real masses of snow” would at least be conceivable again.
Onset of winter with a lot of snow in Germany?
La Nina is imminent
Europe is already being "bombarded with snow," said BBC meteorologist Susan Powell a few days ago.
However, their prediction related mainly to Scandinavia.
But in Germany, too, there may be a severe onset of winter with snow chaos *.
Another weather phenomenon that affects winter in this country could be to blame for this.
“This winter there will be a La Nina event for the second time in a row,” explains Borau.
The significantly cooler ocean currents in the Pacific called La Nina caused insane masses of snow in Germany last winter.
Winter weather: phenomena favor a white Christmas
After all: the weather phenomena also favor a white Christmas.
Using the example of Cologne,
wetter.de
shows
: “Shortly before Christmas, it is relatively cold with only slight plus degrees and there is also precipitation.
That could be enough for snow. ”Even if storms are raging, as was the case recently with Tief Ignatz, that could speak for snow at Christmas *.
Shortly before Christmas it is relatively cold and there is also precipitation.
That could be enough for snow.

In addition, should it be "crisp cold" at this point in time?
So do we spend Christmas and New Year's Eve shivering and in meter-high snow?
The next few weeks will show whether this will happen.
Then the long-term forecasts of the European and American weather models will also become increasingly more precise.
White Christmas: shock for snow fans, but ...
The latter, however, had recently put a damper on all snow fans *.
Because according to the latest calculations, the winter of 2021/22 should not bring as much precipitation as the previous one.
However: December should start with plenty of snow - and that could in turn stir up hope for a white Christmas.
