zieht, fließt von N her kältere Luft in den N-lichen 
Ostseeraum ein. Trotz kühler Nächte ist durch den 
deutlichen Temperaturanstieg während des Tages 
m Finnischen und Rigaischen Meerbusen sowie in 
der Bottensee mit einem relativ raschen 
Eisrückgang zu rechnen. In der Bottenvik werden 
windbedingte Anderungen der Eislage vorherrschen: 
Das Eis auf See wird in SW- bis SE-liche 
Richtungen treiben und sich dabei auflockern.

flow into the northern region of the Baltic Sea. 
Jespite cool nights significant increase of air 
temperatures during the daytime will result in a 
rather rapid ice retreat in the Gulfs of Finland and 
Riga as well as in the Sea of Bothnia. In the Bay of 
Bothnia wind-induced changes of ice situation will 
dominate: The ice at sea will drift southwestwards 
to southeastwards, and it will loosen thereby.
