  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).

2nd UPDATE  26. Dec.2012; 

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.

  1st UPDATE  21. Dec.2012

Previous post 09 Dec.2012 – below -

  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 .

Are we heading to severe Baltic Sea ice conditions
by 30th December 2012?
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.
