ИСТИНА

There are various estimates of the trends of certain meteorological parameters in different water areas and coastal zones of the Russian and rest Arctic regions. Taking into account the increasing number of dangerous phenomena and outlooks for the Arctic coast, the task of providing the region detailed hydrometeorological and climatic information with a horizontal resolution of at least several kilometers becomes particularly topical. To get there, we will use well-known regional climate model COSMO-CLM v5.0. The regional reanalysis for Russian Arctic, an integrated archive of hydrometeorological parameters with a spatial resolution of less than 5 km, will be obtained for the first time after long-term simulation experiments. Detailed hydrometeorological fields in the Arctic over a long period (1980 - 2016) will be derived by the two-step downscaling technology with ~13 km and ~4 km domains and will cover most of Russian Artic (western Arctic seas more detailed). The regional reanalysis output is possible to use as inputs to modelling the ocean´s characteristics (wind waves and dynamics), coastal ecosystems (turbulent heat fluxes, greenhouse gases), more detailed research of individual phenomena on nested domains (extreme situations, hazardous weather events), analysis of trends in the frequency of occurrence of extreme events and features of their spatial distribution, the hydrometeorological regime of coastal areas studies, climatology and tracking of polar mesocyclones, etc.
