Summer Sea Surface and Air Temperature Forecasts for the White Sea Region Using a Coupled Ocean–Atmosphere Model

This paper presents the results of forecasts of the fields of hydrometeorological parameters using the coupled ocean–atmosphere system for the White Sea region for the period from June 2, 2015 to September 1, 2015. The coupled system included three models: atmospheric WRF-ARW, oceanic ROMS, and wave SWAN. The skills of sea surface temperature and 2 m air temperature forecasts have been estimated. The systematic overestimation of the computed sea surface temperature values relative to the OISST analysis data is 0.4°C. The forecast of the 2 m air temperature was generally more successful when using the coupled system than with the WRF-ARW model, and the improvement was observed mainly in the land areas immediately adjacent to the White Sea. Time intervals in which the influence of the sea on the forecast of 2 m air temperature was maximal and minimal are given.
