Polar air everywhere
– January 1940’s polar conditions
Thesis
January 1940 was very cold everywhere in the Northern
Hemisphere, Europe, China and the United States. This became possible
because the atmosphere lacked the volume of humidity it usually has at
that time in winter. The low level was caused by WW II which had just
started in Europe on September 1st 1939, and a small contribution by
the war in China can not be completely be excluded.
Facts
Since WW II commenced in autumn 1939, excessive rain
fell in Western Europe along the front line from Belgium to
Switzerland, particularly during October and November, while the United
States simultaneously experienced an extremely dry November, and a
record dry period lasting from October to December 1939.
In late 1939 there was a disruption of the general
circulation. The war at sea in Europe’s northern home waters was the
main cause. A contributing factor was the ‘imbalance’ of air moisture
in the global north. Deprived of common humidity by military ‘rain
forcing’ in Western Europe, arctic air met little resistant down to the
mid latitude in January 1940.
The event occurred according to ‘marks’ that showed
the limited range, for example, that it was too warm in eastern Canada
and normal in Switzerland and in the south.
Evidence
This investigation has analysed the US Weather Bureau
precipitation data for late 1939, showing that the heavy rain in Europe
correlate perfectly with a record dry time in the USA, about which Dr.
James H. Kimball (local head of the US Weather Bureau) said: that the
November was unusual because of its dry air, as reported by The New
York Times on January 7th 1940. The cold spell in January was the
immediate consequence of the excessive ‘rain-making’ by military
activities in Western to Central Europe.
Conclusion and further reading
The cold January of 1940 all over the northern part of
the Northern Hemisphere can be directly linked to the military
activities in Europe since September 1939, that might have contributed,
albeit not generated the arctic North European war winter 1939-40,
which lasted until March, elsewhere, in USA and China, the cold spell
took reign in January 1940 only. Rain_Making (2_31),
and USA dried out (2_32), and War in
China (2_33).
