Unseasonably cold weather will possibly grip
northern Europe again from late February into spring, after a comparatively
mild spell in late January, as stated by U. S.-based Weather Services
International (WSI) on Monday. WSI thinks that the moderation in temperatures seen
in late January, after the coldest December months since records began for the
United Kingdom to last into early February.
But WSI the specialist for the weather-sensitive energy industry foresees
abnormally cold weather returning to major part of northern Europe towards the
end of next month, dragging down the average temperature for the February-April
period. WSI stated that the current mild spell for most parts of northern
Europe happened due to the North Atlantic Oscillation (NAO) oscillating from
negative to positive in the month of January.
Meteorologists state that a negative NAO usually indicates to colder winters in
northern Europe and WSI warned in the month of October that the negative value
for the pressure difference between areas of the north Atlantic would possibly
mean a very cold start and end of the winter with a mild spell in the middle.
According to WSI Chief Meteorologist Todd Crawford at some point in time later
in the month of February or early March, one can expect a return to more
strongly negative NAO conditions.
At that point, one can expect a return to more severe and widespread
below-normal temperatures across majority part of Europe, which will well last
into spring. Crawford further started that the biggest uncertainty for his
February forecast was that the strong negative NAO could return earlier than
expected.
Bitterly cold weather in most of the parts of northern Europe at the end of
2010 drove up natural gas prices in Britain, where about two thirds of homes
rely on gas for heating, as demand went up to hit record levels and exhausted
stocks early in winter.
