* The storm surge of January 1987 is described in chapter 6 as a storm surge with 2 peaks
The definition of a storm surge provided by Majewski (1989) gives a very good impression of
the dangers of a storm surge but fails to specify the water level that would exist "at a given
time and place without stormy onshore winds affecting sea levels at the coastTherefore,
in the 1990s, a characteristic indicator called “daily reference level” (Sztobryn, Kahska,
Krzysztofik, Kowalska) was included in the specification of storm surges at the Hydrological
Forecasting Office of the maritime branch of IMGW in Gdynia. This one-dimensional
parameter [cm] is described in chapter 3.2.
The parameter allows the determination of the beginning and expected end of a storm surge,
and thus its duration, which is highly useful in flood combating.
In selecting the 73 storm surges that have been analysed in this monograph, the precise time
at which the sea level exceeded the above parameter was considered the beginning of the
storm surge.
