Water level fluctuations in the Odra mouth area in relation to passages of deep low-pressure systems

The Odra River mouth area is affected by storm surges caused by passages of deep low-pressure systems over the Baltic Sea. The surges are the result of wind action and changes in atmospheric pressure at the sea surface. The two effects may be additive, in which both factors increase or decrease the sea level on the coast, or they may be non-additive, where one factor increases the sea level and the other decreases it. This paper discusses the role of the wind field and changes in atmospheric pressure in the duration and extent of storm surges in the Odra River mouth area.
