[1] Surkova G., Krylov A. Extremely strong winds and weather patterns over arctic seas // GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY. — 2019. — Vol. 12, no. 3. — P. 34–42. Strong wind is the main cause of storm sea waves. In order to minimize risks and damages from this phenomenon in the future, climate projection is required. Extremely high wind speed was studied for 20-21st centuries over Arctic seas on the base of ERA-Interim reanalysis data (1981-2010) and CMIP5 models ensemble (RCP8.5 scenario, 2005-2100). It was proposed to use two approaches for investigation extreme wind events. The first one is traditional and involves direct analysis of wind speed data. It was used for the whole area of the Arctic seas. The second approach is based on the assumption that local and mesoscale extreme weather events are connected with largescale synoptic processes. As it was shown before for the Black, Caspian and Baltic seas, it is possible to make climate projection of sea storm waves indirectly, studying configuration and intensity of sea level atmospheric pressure (SLP) fields which are supposed to be the base factor of the wind speed and thus of wind waves. In this way, it is not necessary to run long-term simulations with a sea wave model to predict storm activity for the future climate. It is possible to look for the projection of storm SLP fields, which are simulated by climate models much better than the wind speed required for a wave model. This method was implemented for the high wind speed events over the Barents Sea. Four major types of SLP fields accompanying high wind speed were revealed for the modern climate. It was shown that the frequency of their occurrence is expected to increase by the end of the 21st century. [ DOI ]
