Cold winters in Central Europe - the result of violations of the mechanisms of ...
According to German scientists from the Institute of Polar Research, Alfred Wegener name (AWI) and the Helmholtz Research Center of the Earth (GFZ), heating the air from the waters of the Arctic Ocean increases the vertical circulation, because the warm air mass rises, being replaced by colder. As a result, the lower atmosphere are unstable, and seasonal ...
One of the established systems of air pressure, which is suffering because of it - so-called Arctic Oscillation to seasonal Azores high and Icelandic minimum. In conjunction with each other, they create a gradient, and if the difference in pressure is high, forming a strong wind, from the Atlantic bringing warmer air masses. This trend, reeking moisture mountainous Central Europe, offers a warm and snowy winter. If air flow is not formed, then to Europe gets a cold and dry air from the Arctic, as happened the last two years.
The story of the day. In the embrace of the elements: In the Ukraine are Siberian winter.
Calculations of scientists showed that the difference in pressure between the Azores high and Icelandic minimum is reduced in those years when the Arctic ice is melting more.
Scientists have isolated two mechanisms in the Arctic warming closest to the surface air layer, both the process started by the melting ice. First, the ice retreated, leaving all the big areas of open water, which, in contrast to the bright surface of the ice with a high albedo - reflectivity index of the surface absorbs solar radiation and heats up. Then, upon the occurrence of seasonal frost, water masses give a warm air. In addition, the fall and winter ocean, devoid of sea ice shield, gives off heat to the atmosphere. Such large-scale climatic phenomenon in the Arctic is called the ...
Scientists emphasize that their study describes the mechanism of the climate in general and, therefore, may be seasonal and regional exceptions caused by other factors in the formation of weather.
... This should help people to gradually adapt to climate change ...
Previously, scientists have identified a genetic mutation that leads to such immune diseases like cold and allergy manifested severe immune reaction to low temperatures.
