Polar cyclones: observations, reanalysis, modeling / Nesterov E.S. // Hydrometeorological Research and Forecasting, 2020, no. 1 (375), pp. 65-82.

A review of polar cyclone studies in the Norwegian, Barents and Kara seas is presented. It is found that a favorable condition for the polar cyclone formation is a cold air outbreak to a relatively warm sea surface. The intensification of polar cyclones is facilitated by the latent and sensible heat fluxes on the sea surface. Polar cyclones are most frequently generated at the ice edge and in the coastal areas. Polar cyclones are reproduced in the Arctic System Reanalysis more successfully than in the ERA-Interim, MERRA, and other reanalyses. The use of the ERA 5 reanalysis, which replaced the ERA-Interim, is promising.
