Abstract

The trends in the climate normals of the frequency of strong winds that were registered during the period of modern climate warming (1961–2020) over various parts of the Northern Sea Route are studied. The information of the ERA5 reanalysis is used. The total duration of winds exceeding 10.8 m/s during each month is used as an indicator characterizing the frequency of strong winds. Based on these data, the climate normals of the frequency of strong winds for the base (1961–1990) and modern (1991–2020) periods are determined. The areas of the Northern Sea Route with an increase in climate normals for the modern climate period in relation to similar indicators for the base climate period are identified.
