March  2002
The  last  winter  month  started  relatively  cold,  with  night  frosts.  Initially,  Atlantic  troughs  still  led  to  an
inflow  of  moderately  warm  maritime  air  from  the  west,  but  anticyclones  over  Scandinavia  soon  brought
cold  polar  air  which  caused  the  maximum  daily  temperatures  to  drop  to  3  -  4  °C  on  14  March  and
between  24  and  26  March.  In  the  nights  of  2  and  3  March  as  well  as  26  to  30  March,  light  air  frost  was
recorded  in  Ueckermunde.  At  the  end  of  each  of  these  high-pressure  spells,  southerly  winds  caused
inflows  of  very  mild  air  masses  from  the  Mediterranean,  with  spring-like  temperatures  ranging  from  14
to  18.6  °C  (Ueckermunde).
While  in  the  inner  coastal  waters  the  surface  temperature  (3.4  -  6.6  °C)  was  on  average  more  than
1  °K  above  normal,  the  water  temperatures  in  the  eastern  regions  of  Mecklenburg-Vorpommern  were
mostly  normal.
