Negative Surges in the Southern Baltic Sea 
did not record any negative surges in May, June, 
July and August. These are the months in which 
strong winds or low-pressure systems with gale- 
force winds occur only rarely. The different west- 
to-east distribution is attributable both to the bay 
effect and to other local conditions.
