1. Sc. in geography Said Safarov, head of the Department of Caspian Hydrometeorology at Institute of Geography named after Acad. H. Aliyev of ANAS, explained the reasons for the formation of a thick layer of ice in the northern part of the Caspian Sea.

He said that the northern part of the Caspian Sea freezes every year, so the presence of ice here is not surprising. According to the scientist, the water level in the northern part of the Caspian Sea is lower than in other regions. On the other hand, the temperature of the Caspian Sea is not high here. Therefore, the northern part of the sea freezes almost every year:

“However, in December of this year, severe cold weather is observed in the Caspian Sea, in general in the south of the European part of Russia. Therefore, the freezing rate this year is high, and according to published data, this figure even exceeds 30 percent. Depending on the strength of the cold, the thickness of the ice layer should be large. "

Safarov noted that in terms of climate change, temperatures across the planet have recently increased. However, the temperature change was not uniform over the months. In the past 30 years, in some months - March, August, October, although the temperature has risen sharply, in some places by 1 degree, in places by 1.5 degrees, in November and December there is no sharp warming, in some places the weather remains stable, in some places even 0. The drop is observed temperatures is by 2-0.3 degrees:

 “The northern part of the Caspian Sea can be attributed to the same zone where the decline was observed. Thus, both climate change and local anomalous cooling of air temperature in some places may in some years lead to a large thickness of ice in the northern part of the Caspian Sea. "

It should be noted that anomalous ice thickness was found in the north of the Caspian Sea. According to Roman Vilfand, scientific director of the Russian Hydrometeorological Center, in recent days, severe frosts have been recorded in the south of the European part of Russia, and first the Sea of Azov froze, and then the northern part of the Caspian Sea.

Wilfand said that the thickness and area of ice in the Caspian Sea is 30% more than in previous years.
