Climatology of extreme downslope windstorms in the Russian Arctic
This paper presents the climatology of downslope windstorms in the Russian Arctic – bora on Novaya Zemlya, windstorms on Spitsbergen, in Tiksi and Pevek, bora on Wrangel Island – in connection with the large-scale circulation. Statistical analysis of wind speed and air temperature during windstorms,...
