Flooding Far East
At the end of July 2013 the Far East (Russian territory) and northeast China suffered devastating effects of natural forces.On a fairly large area occurred extensive flooding, water flow in the rivers has risen significantly.
Amur River, the normal flow of water which is 18-20 thousand. Cu.m. per second, it has risen so much that the water consumption reached a value of 46 thousand cubic meters.sec, which is almost three times higher than normal.
Indeed, the floods of this magnitude in this region did not happen for a long time.It is believed that this happens every few hundred years, and the last as a great flood happened about 115 years ago.But peopl
e are impressionable upon the occurrence of major disasters often tend to think that it's the beginning of the apocalypse.
climate in the Far East - in part monsoon and the rainy season starts just at the end of July and lasts for the whole of August.Even this would be enough to provide for the possibility of flooding at this time.From the sea come the cyclones that are "stuck" in the mountains, yet the clouds do not devastate all his reserves.Wind direction if the phenomenon is constantly changing, new clouds come to replace the previous, rain pours an endless stream.So it usually is, but not so severe flooding as happened in 2013, there has been additional reasons.
cyclones and anticyclones are subject to self-regulation mechanism of the air mass, which from year to year is behaving more or less constantly, which causes the notion of climate change.But in 2013 the balance of this mechanism was somewhat disturbed.In the Western Pacific anticyclone hung high pressure, which is not allowed to leave the anticyclone Amur Region Far Eastern territories.It turned out that by July 2013 the Amur region was formed on the stationary zone, in which for two months "hang" severe tropical cyclones, saturated with moisture.
settlements of Russia in the Far East have been hit hard, but only one person died.China was less fortunate, who died more than a hundred, as many more missing.
Due to constant rain, all areas of the Amur River basin, prone to flooding, were filled with moisture.Usually floods occur in one or more of them, but in 2013 there was so much water that turned out to be crowded all the flood areas.
«On hand" flooding was the fact that the winter from 2012 to 2013 gives a very snowy, and spring came late.The ground was already saturated with water to excess rains just did the rest.
Hydrologists believe that one of the constraints that prevented flooding in the past - vast forests, which in recent years severely damaged by uncontrolled logging and fire.
