PROGNOS
18-23 mars 2003
Högtrycket vid Skottland förskjuts sakta till
södra Östersjön. På onsdag-torsdag utbreder
sig kalla nordvindar över Bottniska viken och
Östersjön. De följs av en högtrycksrygg, som
passerar åt sydost över Skandinavien på
torsdag. I slutet av veckan rör sig ett djupt
lågtryck österut över Ishavet varvid milda
sydvästvindar utbreder sig över Skandinavien.
Medeltemperaturen för perioden blir över den
normala i de svenska farvattnen med tillfälligt
kallare väder på torsdag. Det betyder
medeltemperatur mellan –9 och +2 grader på
Bottenviken och Norra Kvarken, mellan –5
och +3 grader på Bottenhavet, Ålands Hav,
Östersjön och Mälaren. Plusgrader i övriga
svenska farvatten.
Isen på Bottniska Viken väntas under tisdagen
driva nordost- eller ostvart och råken längs
svenska kusten fortsätter att vidgas. Dock kan
isen tillfälligt packas syd om Nordvalen.
Senare under onsdagen och på torsdag väntas
sydlig isdrift. En råk kan öppnas i norra
Bottenviken medan isen packas samman
utanför Bjuröklubb och möjligen ned mot
Holmöarna. Även på Norra Kvarken och
nordligaste Bottenhavet väntas isen driva
sydvart och nya breda råkar bildas i området
Nordvalen-Väktaren-Sydostbrotten. Snabb
nyisbildning väntas på råkarna. Den redan
spridda drivisen på norra Östersjön bryts upp
alltmer och skingras. På Vänern väntas
efterhand långsam isavsmältning.
FORECAST
18-23 March 2003
The high pressure near Scotland slowly will
move to southern Baltic. On Wednesday-
Thursday cold northerly winds will penetrate
the Bothnian bay and the Baltic followed by a
high pressure ridge on Thursday. Later this
week a deep low will move eastward on the
Ice sea and mils southwesterly winds spread
over the Scandinavian waters.
The mean temperature for the period will be
above the normal, but shortly interrupted by
cold weather on Thursday. This means mean
temperatures between –9and +2 degrees C
on the Bay of Bothnia and the Quark,
between –5 and +3 degrees C on Sea of
Bothnia, Sea of Aland, the Baltic and lake
Malaren. Remaining waters above zero.
The ice on the Bothnian Bay during Tuesday
wilkl be adrift northeast- or eastward and the
lead along the Swedish coast widen. Shortly
the ice may press south Nordvalen. Later on
Wednesday and on Thursday southerly ice
drift. A lead may open in the northern Bay of
Bothnia, but press off Bjuroklubb and
possibly towards Holmoarna. Also on the
Quark and northernmost Sea of Bothnia the
ice will be adrift southward and new wide
leads open in the area Nordvalen-Vaktaren-
Sydostbrotten. Rapid new ice formation in the
leads. The open drift ice on northern Baltic
will break up and dissolve.
On Lake Vanern slowly ice melting.
