Unprecedented wind shift after WWII
commenced, one in over 100 years  

Post 03  Dezember 2017

As early as October 1939

 At the end of October 1939 the “Seewarte” (the German Naval weather service) analysts had realised that the wind The change of wind direction in October 1939Extreme wind-shift in winter 1939-1940 and coldest winter in 100yrspattern over Northern Europe had changed completely (Fig.1. Unfortunately they lacked the competence to read the signs. According to their observations:

    Hamburg reported winds from the North-Eastern quadrant on almost two thirds of the dates observed (33% easterly winds out of 65%) while North-Eastern winds accounted only for a quarter (26%) of several previous years’ averages. Otherwise the most frequent direction of the wind – South-West (24%) – accounted for 9% of all cases. Thus the observations at this station alone show what the weather charts of an extensive area will obviously indicate as well (Seewarte, Nov. 02, 1939), next Figure C5-8.

This is a very strong and clear indication that huge air masses moved  from Eurasia continent to West Europe. Unusually high evaporation affected by naval war, caused a shift in the wind direction. While the water of the seas was ‘stirred and turned’ the ‘steam’ rose upwards into the sky, causing an air inflow from easterly directions, which A rare wind shift after 100yrs during the first naval war winter in 1939-1940subsequently prevented low-pressure systems to travel along the west-wind-drift channel via North Sea and Central Europe into the eastern hemisphere.

The rare wind from North-East

Based on works of different authors, Drummond explains that, from 1788 to 1942, only 21 winters but of 155 had easterly residuals; only 7 since 1846 and only three since 1903, namely 1904 (SSE), 1929 (ESE), and 1940 (ENE). The latter is the most stunning one. In only three years, the wind changed to the north-east sector. That happened in 1814 (NE), 1841 (NE), and during the winter of 1939/40 (ENE). It must have had a cause, which should be identified. An interesting aspect could be that the other two war winters of 1940/41 and 1941/42 did not make it in the list of years with winds from the east. They had, like the other 153 winters, winds from the west, although they came along with a considerable cold average. That made the exceptional winter of 1939/40 even more interesting.

An urgent need to research

Temperature anomaly situation from 1st war month in 1939It is difficult to understand that science has not picked up the wind-shift issue for a Temperature anomaly situation from 2nd war month in 1939better understanding a possible link between naval war and climatic change. If the winter wind in Western Europe did blew only two times in about 150 years from NE something extraordinary must have happened. As the general situation had been ‘normal’ until World War II commenced in September 1939, the question is Temperature anomaly situation from 3rd war month in 1939inevitable: Why so suddenly and why in Europe? The logical answer would be to assess all circumstances, and if there is no ground for anyTemperature anomaly situation from 4th war month in 1939 ‘natural’ reason, it seems irresponsible not to consider an anthropogenic cause. Actually war has a profound impact on air and sea. Particularly naval warfare during autumn churn the sea over huge areas, and thus release more quickly the heat stored during the summer season, with significant impact on the atmosphere and the sea water temperature. It is like stirrng the hot coffee to cool it down.  Subsequently icy air more easily can travel from Siberia to the Atlantic shore of Western Europe. It happened only few months in war, resulting in the coldest winter in many regions, in more than 100 years. It is high time to research the wind-shift seriously.
