A diving cyclone is moving to the European part of the Russian Federation, because of which abnormal frosts are waiting for Russians. According to the Hydrometeorological Center, already next week the temperature outside the window will be on average minus 20 degrees.
“As this cyclone, which we call a diving cyclone, moves, even colder air will be drawn in. And on December 21, at night, the temperature will drop to minus 16-21 degrees, and during the day it will be in the range of minus 12-17 degrees. Next, different weather scenarios are considered. But many forecasters are inclined to the opinion that the frost will increase, Lyudmila Parshina, head of the laboratory of the Hydrometeorological Center of Russia, told the Russian newspaper .
In the coming days, the Atlantic cyclone will bring heavy snowfalls to the Leningrad and Arkhangelsk regions, to the south of Karelia.On December 16, wet snow will pass in the Moscow region. 40-degree frosts in the coming days will come to the north of Siberia. And in the south and south-east of Yakutia at night it is already over minus 50 degrees.
Why is a diving cyclone so called and where is it moving from?
The main feature of the “diving” cyclone is its trajectory. Unlike most cyclones that move along the latitude from the west to the east, this cyclone goes from the northwest to the southeast, and at an impressive speed (up to 50 km/h).
According to forecasters, the cyclone originates over the Greenland and Norwegian Seas (at the top of the geographical map), and then, as if bursting (diving) to the southeast deep into the Eurasian continent. Within a day, they are over the Lower Volga region (at the bottom of the geographical map). Therefore, meteorologists call it among themselves a “diving” cyclone because of the speed of movement.
How does a diving cyclone change the weather?
With «diving» cyclones are associated with sharp fluctuations in the weather. It changes from warm to Arctic cold, as forecasters say. Often such cyclones move one after the other. Then in the regions over which the “diving” cyclones sweep, an unstable temperature is established for several days (and sometimes weeks).weather. This is manifested in sharp and frequent fluctuations in atmospheric pressure, temperature, wind and precipitation (sleet, snow, blizzard in places, snow drifts on roads).
