The long-term trends point to the interesting possibility of a collapse of the polar vortex, perhaps in a very “explosive”.

Analyzing the temperature anomalies to the surface of the sea, and at some points mainland, we can get a sense of the overall pattern that has preponderado over the past few weeks:

A sudden stratospheric warming (SSW) is an event where the polar vortex of westerly winds in the winter hemisphere abruptly (i.e. over the course of a few days) slows down or even reverses direction, accompanied by a rise of stratospheric temperature by several tens of kelvins. This is considered to be the most dramatic meteorological event in the stratosphere.

Cold Wave in China on Saturday, 22 December, 2012 at 11:45 (11:45 AM) UTC.

Description
China’s National Meteorological Center(NMC) on Saturday kept its blue alert for the severe cold wave that is sweaping many northern China regions. The observatory said temperature drop will continue to decline from the weekend to Monday after many parts of China had started to experience the lowest temperatures this winter. Most parts of China, except the central and southwestern regions, will see temperature fall by 6 to 8 degrees Celsius in the next three days, with some parts of north and northeast China to witness a drop of 10 to 14 degrees Celsius, according to the NMC. On Saturday morning, temperatures in parts of Xinjiang, Qinghai, Tibet, Gansu, Shanxi, Hebei, Inner Mongolia, Liaoning, Jilin, Heilongjiang, Fujian and Guangxi dropped by 6 to 10 degrees Celsius from a day ago, and by 12 to 16 degrees Celsius in parts of Liaoning and Jilin. China’s meteorological disaster alerts are categorized as blue, yellow, orange and red as the severity of disasters ascends. The NMC also forecasted small to moderate snow for parts of Xinjiang, Gansu, Inner Mongolia and Hebei while heavy snow for Shandong Province on Saturday. Parts of south China and Guizhou Province will see sleet, while freezing rain will fall on west and central Guizhou.

Il fait toujours un froid glacial en Russie. Aujourd’hui, la température est descendue jusqu‘à -30° à Moscou. Les écoliers ont été autorisés par la mairie à rester chez eux. Certains ont quand même mis le nez dehors pour profiter du temps libre. En Pologne, le mercure est subitement remonté dans le centre et dans l’Ouest, mais l’Est du pays est toujours en proie à un froid glacial. La vague de froid qui frappe l’Europe de l’Est ces dix derniers jours a fait au moins 220 morts: 88 en Russie, 83 en Ukraine et 49 en Pologne. Les températures sont de douze degrés inférieures aux moyennes saisonnières. Normalement, un tel froid n’arrive pas avant les mois de janvier ou février. En France, au contraire, c’est un peu l‘été en hiver comme ici à Arcachon. Les vacanciers ont ressorti tee-shirts, shorts et maillots de bain pour se prélasser au soleil, voire même se baigner, malgré une eau à quatorze degrés.
