Meteorologists Have Found Connection Between Record-breaking Cold Weather In The U.S. And Warm Winter In Russia

The natural climatic variations were caused by so-called Rossby waves. Natural variations in climate are the reason why extreme cold in North America is accompanied by an unusually warm winter in Central Europe and the European part of Russia.

The World Meteorological Organization (WMO) spokesperson Claire Nullis informed journalists at briefing in Geneva. "What we see is the part of natural climatic fluctuations. Rossby waves is one of the reasons explaining why winter is extremely cold in the United States while in Europe it is warmer than usual," she said. It is a question of low-frequency planetary waves, which are one of the origins of the jet streams – strong high-altitude winds that blow from west to east. "It does not always happen like this. It depends on the position of the jet stream, – Nullis explained.

Similar phenomenon was observed in 2010 winter, when very low temperatures were reported in the most of the Northern Hemisphere. The cold weather in the U.S. not always automatically brings heat to Russia, but now it is just like this." Frost in the United States. Last days, the residents of the United States have experienced the most severe frosts within the last 20 years. According to WMO, due to the ice funnel that brought North Pole air masses over the United States, the temperature dropped below freezing point in 48 out of the 50 American states (except Alaska and Hawaii).  The temperature on the East Coast and in some southern locations dropped down to -40 C °. The record was set in one of the largest American cities of Chicago (Illinois), where thermometers showed -27 C °. 'Frosty achievements' were also reported in South Carolina, Florida, Georgia, Texas, Missouri and New York. At least 20 persons died because of extreme colds.

European anomalies. Meanwhile, the temperature in Europe, in contrast, is extremely warm. For example, in France on Wednesday, average temperatures were 5-9 C ° above normal. In the resort of Biarritz on the Atlantic coast of the country, the temperature hit +17,9 C ° at seven o'clock Thursday morning. Abnormally warm weather settled in Central Russia. As WMO pointed out, +2 C ° registered in Moscow on Thursday, is 11 C ° above the norm. In addition, December of 2013 was the warmest in the history of meteorological observations in Murmansk. Dwellers celebrated New Year with no snow. According to the Hydrometeorological Center of Russia, Russian winter will return to the European part of the country at the beginning of next week.

Possible aftermaths. According to scientists, such climate shifts can cause serious damage to flora and fauna, as well as to agriculture. For example, tree buds start swelling and trees themselves quite short hibernation period, tuning up for spring in some European countries like Czech Republic, Slovenia and Ukraine. However, the upcoming colds will force the nature to stop the transition to summer mode. Later on, re-blooming will start later and will be weaker. Due to the high temperatures, the lack of snow on the fields and moisture, which stagnates in the soil for more than five days, winter crops keep growing instead of waiting for spring. If the snow will cover fields in this condition it can end up with so-called snow mold, which will cause the death of all winter crops. Environmentalists are concerned that some species of animals and insects can get harmed as well. For example, warming wakes up bees and other insects, as well as bats, but they have nothing to eat. The search for food will lead to exhaustion, which, in turn, will result in death when frosts hit back.
