About the Role of North- and Baltic Sea

Three month ago, in December 2012 - HERE, we question, whether severe Baltic sea ice conditions are ahead. Now it is time to archive some information on the extraordinary cold and snow rich March 2013 (HERE & HERE), Great Britain fears that: “The big freeze gripping the UK could last until almost the end of April, with sub-zero temperatures expected for the rest of the week”  say THE TELEGRAPH/UK ( 7:34AM GMT 27 Mar 2013).  

After a moderate Jan.& Feb. the March is one of the coldest for many decades (Fig 1), and will stay that way at least until early April (Fig. 4)., whereby West-Europe sees a lot of differences between north and south. The UK is in-between where maritime and continental air clashes (Fig.2).  Fig. 3 indicates air pressure and T°C on 27.March, 07pm.

 A contributing role of the North Sea is obvious, when taking into account the SST of the North Sea, which is, in week 12 of the year (next Figure -5a.), about 2°C colder than in previous years (Fig. 5 to 9 ) :

Note: This year SST during the 12th week are only about 2°C lower than during the pervious years (2008 -2012; Fig. 5 to 9), but the impact on Great Britain and Northern Europe significant.

  The unusual low North Sea SST contributes the cold and snowy condition in the UK . How this situation has becoming about, and whether it has an anthropogenic input is unknown: Until now science has never question the impact of human activities in the marine environment on the salt and heats structure. The extraordinary conditions offer a good chance to make progress in this matter.
