Understanding of Polar Air Outbreaks in Eurasia Using Climate Indices

Zusatztext

I believe that any research should bring something new to the table. I hope you will find it interesting! Polar air outbreaks from the Arctic can be categorically considered as extreme weather events because monthly temperature anomalies both in the Arctic and middle latitudes may exceed 20 degrees. It was found out that both the North Atlantic Oscillation and the Arctic Oscillation indices are not sensitive to the two completely different types of polar air outbreaks in terms of distinguishing them. The physical origins of polar air outbreaks were highlighted and the classification of them was carried out. Based on this classification a conclusion about the existence of the North Siberian anomaly was made. And, according to many features, this anomaly can be treated as the one more action center of the atmosphere. This finding has allowed us to introduce a new climate index, which was called as the Atlantic Arctic Oscillation index. This index permits us to identify the two types of polar air outbreaks with the higher level of recognition probability.

I have been interested in meteorology since I was a child. Clouds, wind, precipitation, water, ice, etc. have always attracted my attention. From 2012 to 2016 I studied for a bachelor's degree at the Russian State Hydrometeorological University, where I understood completely that my life is impossible without geosciences.
