18.2 degrees Celsius – even that was what the thermometers in the Sudetes foothills showed on Monday morning. As the presenter of tvnmetro.pl, Tomasz Wasilewski, explained on TVN24, such high values are related to the occurrence of the phen effect. However, for such an increase to occur, several conditions must be met.
On Monday, the weather in Poland will be influenced by the Sigrid low. Our country is in its warm zone, which means that the next hours will bring us calm weather and much higher temperatures than usual at this time of year.
Weather sensation
The first signs of a thermal anomaly could be observed already at night. As the data shows IMWMon Sunday at 8 p.m Karpacz thermometers at the weather station showed 12.4 degrees Celsius. An hour later the temperature rose to 16 degrees Celsius, and at 4 a.m. on Monday it was already 16.9 degrees Celsius.
It was also extremely warm there Szklarska PorębaBogatynia and Pszenna – there at At 5.40 an air temperature of 18.2 degrees Celsius was recorded.
Huge increase in temperature
As the presenter of tvnmeteo.pl, Tomasz Wasilewski, explained in the program “You get up and you know”, the extremely high temperatures in the Sudetes are related to the occurrence of the foehn effect. It is a strong, warm wind blowing from the mountains towards the valleys.
– Of course, this happens with appropriate circulation created by the wind, but also with the inflow of warm air. Today, both of these conditions are met, he explained.
How long will the high temperature at the end of November remain in the Sudetes? It all depends on the wind and whether it will continue to fall from the slopes into the valleys. Wasilewski also noticed that the foehn effect is very local – not all parts of the foothills are as warm as in Karpacz or Pszenna.
– This is a weather sensation on Monday morning, because 17 degrees after -12 or -10 degrees in that region three days ago, this is a huge increase in temperature – added the presenter.
Sunrise in Pszenna was recorded at 7.26.
