Northern Europe’s Mild Winters.

December 2015 - Hamburg, Germany

Abstract: The marine environment of North Sea and Baltic is one of the most heavily strained by numerous human activities. Simultaneously water and air temperatures increase more than elsewhere in Europe and globally, which cannot be explained with ‘global warming’. The climatic change issue would be better understood if this extraordinary regional warming is sufficiently explained. The regional features are unique for in-depth studies due to different summer-winter conditions, shallowness of the seas, geographical structure, and main pathway for maritime weather patterns moving eastwards. The impact of sea activities on the seasonal sea water profile structure is contributing to stronger regional warming, change in growing season, and less severe sea ice conditions. The impact of the man, whether small or large, should be understood very soon and very thoroughly.

Keywords: Human maritime activities, sea temperature increase, North Sea and Baltic warming, change in seasonality, sea ice decrease.

HMS ‘Rawalpindi’ Sinking and Cyclone formation
 The Atlantic Naval Drama 23 – 27 November 1939
Text excerpt form book: “Climate Change & Naval War” 2005

The first sea engagement of naval surface vessels in the North Atlantic occurred in late November 1939. This naval encounter was immediately followed by a rapid decrease in air pressure by more than 50 mb in 48 hours. Can a 15 minutes’ shelling of 600-pound shells produce sufficient ‘butterfly-effect’ to turn a modest low air pressure into a violent cyclone?

Weather was fair on Thursday the 23rd November 1939, Southeast of Iceland, about 200 miles west of the Faroe Island. The big and modern German battleships Gneisenau and Scharnhorst sailed in a flotilla of six naval vessels, when they saw HM Armed Merchant Cruiser Rawalpindi at some distance.

The effect of stirring

The actual winter 2014/15 is up to now no winter in Northern Europa (Fig. 1-2). Can anthropogene activities in the North Sea, Baltic and coastal seas be made partly responsible? Presumably yes! Stirring hot coffee will cool it down. At the end of August the sea areas have gained their maximum potential of warmth. Many ship propellers are plowing through the sea stirring the surface layer to a depth of 15 meters. In the North Sea and Baltic there are continuously up to ten thousand large motor ships at sea. Several thousand offshore facilities on the bottom of the sea or anchored offshore rigs divert currents at sea and influence tides and currents as a permanent resistance against the normal flow of huge amounts of ocean water. (Fig. 3-8) The result is like stirring hot soup. Warm water will come to the surface and the heat will supply the atmosphere with warmth. The air will become warmer and the winters will be milder. The correlation is not to be overseen. It is not relevant to climate research or agencies allowing offshore structures who do not consider such evaluations.

Strong warming during winter season.

The situation at the beginning of the evaluation is obvious. In Europe the mean average temperature during the last century has risen by 0.9C…………………

How serious is MetOffice to understand
a “weather bomb”

posted: 14 December 2014

Reference MetOffice/UK-text:

The matter is about exceptions. Somewhere between 45 and 65 “weather bombs” occur worldwide per year, with more ‘bombs’ occurring in the northern than southern hemisphere, says MetOffice (12 Dec.14) explaining that term as a rapid fall in central pressure of a depression (or low pressure) – it has to fall by 24 millibars in 24 hours in our latitudes to meet the criterion, providing as example the maps from 8th and 9th December 2014 at noon (HERE)



08 Dec.2014 - north-west Atlantic at midday
968 millibar

09 Dec. 2014 – south-west of Iceland , 12h
942 millibar

 75 years ago World War II was just three months old. On 30th November 1939 The Soviet Union attacked Finland . Naval war activities took place in all sea areas from the Biscay to the North Cape . Only three weeks later, a highly spectacular weather event took place on the longest night north of the Arctic Circle off Roest (Lofoten) near the Norwegian port of Narvik . Actually on 20December 1939 a cyclone developed quickly, pushing the prevailing air pressure down by 54.6 mb in 24 hours.



20 Dec. 1939 - Roest/Lofoten;
About 1015 millibar

21 Dec. 1939 - Roest/Lofoten;
< 975 millibar

 The Swedish Weather Annual for December 1939 reported this event noting that the air pressure fell by 12mm within three hours. This matches with hurricane conditions. In addition to this development, the course of the cyclone over the next few days, according to weather charts of “Deutsche Seewarte” is quite interesting:
___ Thursday, 21 December 8  a.m. , 975 mb, ca 100 miles west of Roest/Lofoten;
___Friday , 22 December, 8  a.m., 970 mb, Lula/Sweden ( north Baltic Sea);
___Saturday, 23 December, 8  a.m. 980 mb, Ladoga Lake;
___Sunday, 24 December, 8 a.m., 980 mb, ca. 100 miles south of Leningrad.
 What triggered  the development of this exceptional cyclone in the first place? Discussed here: 
                                                 see EXAMPLE 5.

The principle trigger must have been the ocean off the Lofoten, and other naval activities from Dover to Leningrad may have contributed. The Met Office is well advised to offer competent explanation for such extraordinary event. Their reasoning about the recent “weather-bomb”, would have indicated that the interior of the sea between Greenland and Iceland has caused it.
