That’s it, at least
for now! Any serious sea ice cover in the Baltic can not longer be
expected soon. A peak had been reached on 26th Dec. (Fig.18),
but weakened since (Fig.19, 30/Dec.). Although the ice extent per 30. Dec.
is still higher than the long-term mean per 1st January (Fig.
20), it is likely to remain on a moderate level for at least the next
weeks (Fig. 21), as lower temperatures can only be expected after Jan.07,
(Fig.22). At the end of the
year 2012, the Baltic SST seems to be within the normal range at this time
of the season (Fig. 23 & Fig.24).

Previous
post 09. & 21. December –below-
The sea ice in the Northern Baltic Sea increased significantly, but
is still not close to the level at the same time two years ago. As the
Asian cold snap moved eastwards (see
NTZ, 26/Dec/12), a big increase can not be expected soon. The recent
cold in the north-east had only moderate impact in the south-western
Baltic.

-
East-Europe
and
Central Asia
feel an extraordinary cold December
(H/T NoTrickZone; 21Dec.12), as reported:
___The spate of cold weather that has lasted for weeks in many parts of
Europe has now claimed at least 600 lives Eastern
Europe.
___The Russian RT
reports: The country has not witnessed such a long cold spell since
1938, meteorologists said, with temperatures 10 to 15 degrees lower than
the seasonal norm all over
Russia
. Across the country, 45 people have died due to the cold, and 266
have been taken to hospitals. In total, 542 people were injured due to the
freezing temperatures, RIA Novosti reported.

The cold snap finds a barrier at the shore of the
Baltic Sea
. Currently the
Baltic Sea
still matches average conditions, as indicated in the following images (Source:
The Baltic Sea Portal) increased significantly between 18th and
21st December (next Fig. left & right), and is surpassed ‘normal’
(middle-Fig) today (21Dec). Significant is the sea ice at the
shore
of
Estonia
.

The situation on 8th December 2010, 2011 and 2012.
Posted
on 09 December 2012
Severe sea ice condition appeared in the
Skagerrak
by the end of December 2010, as discussed HERE.
Presumably it has been the most extensive ice cover in the
Skagerrak
since the 19th Century at such an early date. From this post we reproduce
the status on 31st December 2010. The thereon following images
show the current situation. Two images (blue) indicate the mean status in
the Northern Baltic on the 1st and 11th December.
The subsequent three graphics indicate the situation on the 8th
December 2010, 2011 and 2012. In December 2010 there was already slightly
more sea ice as currently. A comparison of the sea water temperatures in
the
Skagerrak
between 2010 and 2012 (enlarge the graphs) show, that they were equal. It
will be interesting how the developments will be during the next three
weeks.
For
the further developments during winter 2010/11
see: A
sudden sea ice increase in the Baltic Sea, February 2011.
