A wind shift in Europe October 1939,

due to naval activities?

Extract from book page 33:

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 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.

·          Remark: This is a very strong and clear indication that huge air masses moved towards the North Sea, presumably caused by unusual high evaporation in this sea area. While the water of the North Sea was ‘stirred and turned’ the ‘steam’ rose upwards into the sky, causing air to flow in from Easterly direction, which subsequently prevented low-pressure systems to travel along the west-wind-drift channel via the North Sea and Central Europe into the eastern hemisphere.
