A tide in the operational model for short-range forecast of current velocity and sea level in the Barents and White seas

The operational model for the short-range forecast of velocity of currents and the sea level of the Barents and White seas is introduced into the automatic system of operational data processing of Hydrometcenter of Russia and works in the operational mode. The tidal block of the model is verified using eight major harmonics of the tide in the Barents and White seas. It is revealed that the model simulates adequately the large-scale features of tidal circulation in the Barents Sea. The model verification is based on the comparison between the diagnostic computation of the total sea level and the observational data on the sea level from the automatic buoy station. Demonstrated is a good agreement between the total sea level computations and the observations in the area of Teriberka settlement. The model takes account of the ice presence and simulates the ice effects on the currents. It is established that the ice presence affects significantly the amplitude and phase of tidal waves, especially in coastal regions.
