Climatic Changes in Thermal Conditions of Sea Areas in the Eastern Arctic at the Turn of the 20th and 21st Centuries

详细

The interannual variability of sea surface temperature and air temperature in the coastal zone and adjacent areas of the East Siberian and Chukchi seas and the Arctic Ocean at the modern stage of the climate warming is analyzed. The analysis is based on data of routine observations at hydrometeorological stations obtained in 1980–2016, global meteorological network data and NOAA reanalysis data. The analysis of the spatiotemporal pattern of temperature variations and the zoning of water areas based on the features of modern climate changes are carried out using the EOF (Empirical Orthogonal Functions), cluster, and correlation analyses. The possible cause-effect relationships between these changes and variations in wind field components and climate indices are considered. The studies revealed, specified, and quantified the modern trends and regional features of interannual variability of thermal conditions in the selected areas.
