The night from Friday to Saturday all over Poland turned out to be frosty. In many regions, thermometers showed below -10 degrees Celsius, and on the ground it was even -21 degrees. As explained by the synoptic TVNmeteo.pl Arleta Unton-Pyziołek, the upcoming nights can bring even lower values.
The Institute of Meteorology and Water Management has published a statement of the minimum temperature value recorded on Friday to Saturday. The lowest value was observed in Suwałki (-12.8 degrees Celsius), not much warmer in Bialystok and Cognition (-12.3 degrees C). The warmest was in Ustcewhere the temperature dropped minimally to -1.4 degrees C.
It was even colder near the ground. The lowest value, -21 degrees Celsius, showed the ground minimum thermometers in Poznań. The lowest decline, -2 degrees C Świnoujście and Ustce.
Where do such declines come from?
Why was the ground temperature so low in Poznań? As explained by the synoptic of TVNmeteo.pl Arleta Unton-Pyziołek, this is due to several overlapping factors. First of all, Western Poland got to the edge of the boom of Fenja from Greenland, whose secondary center is currently overwhelmed by Germany, close to Poland.
– In the boom, which is normal, at night dissolution has already appeared. The lack of a layer of clouds, quilts, promotes strong radiation of heat from the ground and the cooling of the air – explained the synoptic.
In addition, on the edge of the boom stretching from Greenland to Central Europe and the lowlands located above Eastern Europe, there was a strong rafting of Arctic air. In this area, a cold tongue develops, “now still narrow, but over time it will expand and strengthen from the Arctic to the Balkans,” she added.
– The temperature at an altitude of 1.5 kilometers over Poznań was about -13 degrees this morning, which means that in the dissolutions it can be the same at a height of 2 meters, and with a strongly cooling earth the decline can be even stronger – explained the synoptic.
She added that today's values are just an introduction to what is going to happen in the coming days. Nights will bring possible temperature drops at the ground to even -23 or -25 degrees.
