Use of COSMO-Ru forecasting system for polar low’s research: case study 25-27 March 2014
Results of numerical modelling of polar lows observed in the Barents and Kara Seas are analyzed using non-hydrostatic limited-area atmospheric model COSMO-Ru with grid steps 13,2, 6,6 and 2,2 km. The influence of ice cover characteristics on the modelling of generation and develepment of polar low is demonstrated. It is shown also the connection of the wind fields at 300 hPa level with underlying polar low.
