Winter season 2012-2013 year is very different from all the previous trajectories over the past decade "dive" of North Atlantic cyclones, which recovered over the Mediterranean and then sent to the Middle East and West Asia.
In the vast Arabian desert rains are only in the winter, and that no more 2.3
once a month. As a rule, only delays the sky with clouds, and a little pomorosit. Almost the same pattern is observed in the whole of Western Asia, which refers to the belt of subtropical arid deserts.Warm climate and scant moisture made a significant area of Saudi Arabia and southern Read more [...]
How long have you been at the power plant in the winter? Remember how hot exhaust evenly mixed with the cold air? It is easy to convince yourself that the simple burning of fossil fuels (not even the greenhouse gases released by burning it) leads to climate change.In fact, the energy released in this way is very small on a global scale, so the researchers see it as a rounding error. And yet, although the production of electricity does not add a lot of heat, it affects how the heat is distributed. According to new data, in some areas it is clearly visible.Photo Leszek Kozlowski.It is quite Read more [...]
If you look at the graph of the last century the global temperature, eyes rush failure in 1960. Over this period, said a lot of cool. Some point to fluctuations in emissions of aerosols (small particles), which reflect sunlight. Others nod to the Atlantic Ocean circulation, which is called the cycle of changes multidekadnoy Atlantic Oscillation (AMO). The situation is complicated by the fact that the former can affect the second, and the accumulated effect of both.Surface waters that flow into the North Atlantic, cool, approaching Arctic sink into the abyss and come back to the south. It Read more [...]
Usually at the end of January have culmination Siberian winter, when the temperature is lowest in the annual cycle values. But this year, instead? 40 thermometer 3.
During the two-day weekend in the big cities of South Siberia (Krasnoyarsk, Tomsk, Novosibirsk, Kemerovo) registered five temperature records and a few close values for records, when to repeat the absolute maximum is not enough less degree.On Saturday, January 26, noted in Krasnoyarsk 3.4, Kemerovo? +3,3, Novosibirsk? 1.9.

In the upper troposphere (6 to 10 miles) is home to many microorganisms. Their composition varies especially in tropical storms, soobshayut NASA specialists and Georgia Institute of Technology in an article published in the Proceedings of the National Academy of Sciences.Microorganisms play an important role in the life of the atmosphere - they, in particular, influence the formation of clouds and precipitation. At altitudes lower than 5 kilometers of microbial cells up to 3 microns comparable to the number of ice particles of the same size. Living cells can "work" condensation nuclei Read more [...]
In 1995, Saddam Hussein announced that the Iraqi army has in the event of biological warfare potent Aspergillus mold spores. Iraqi president is said, or not said, to check hard. In any case, every American in the mid-90s he was convinced that the wily dictator in their laboratories prepared a myriad of deadly potions. This, along with others, was the ideological basis of the U.S. confrontation with Iraq.No Aspergillus in Iraq were found. The irony, ten years after the execution of Saddam Hussein committed by the Americans in the air, the United States once again in the crosshairs dangerous Read more [...]
Because of climate change in Indonesia in 2012, has experienced more cyclones than it was a few years ago. Meteorologists believe that in the future this trend will intensify.
Press secretary of the Agency for disaster mitigation Sutopo Purva Juvonen said: "Global warming leads to more intense formation of cumulonimbus clouds that trigger the formation of a larger number of cyclones." Mr Sutopo argues that natural disasters of 1200, borne by Indonesians annually, 36% are the sole responsibility of cyclones.Peak cyclogenesis Indonesian meteorologists expected in March-April. Other consequences Read more [...]
Winter recent years has rapidly move into the summer, the trend to a shift in climatic seasons deprive Russians spring, said at a press conference Head Hydromet Alexander Frolov, According to "Gazeta"."Look, in 2012, has long been cold, almost all of March and half of April. And then suddenly came the heat. May was a record warm, even hot in summer. That is, we have actually lost one season - spring, "- said Frolov.
This shows there is a persistent tendency to shift seasons: a long winter, spring is almost absent, warm, and sometimes extremely hot summer, Frolov said.

Over the past 8 years in the Indian city of Shimla not seen such a snowfall, which is just one day completely covered him with a white shroud. 24 hours in the city fell 38.6 cm of snow, which in January will not be repeated in 2005. Then the record was 33.2 cm, and in the next two years, there was no snow at all, and in 2008, for the entire month fell only 1 cm of precipitation. Then they saw a slight annual increase, while in January 2013 will not happen real breakthrough.Now, two days to a number of Shimla fell 63.6 cm of snow, which, by the meteorologists, came to India by circulating cyclone Read more [...]
Snowfall that hit the European countries and Russia at the end of 2012, may be associated with a record reduction in ice area in the Arctic. This opinion was expressed by the representative of the National Climatic Data Center (U.S.), Paul Groisman. "Last September - the absolute minimum ice cover, he went to Greenland, the Canadian archipelago, along Eurasia opened a large area of water," - said Groisman. According to him, the water is not frozen immediately, so the November snowfall may be associated with this. He also noted that 40 years ago, British scientists conducted an experiment Read more [...]
Sudden stratospheric warming the polar vortex split in two. The polar vortex is formed and deepened, when the atmosphere loses heat to space in the dark long winter nights in the Arctic, has been divided into two large parts is being reduced. A series of intense storms in the far northern part of the Pacific Ocean has increased to very long waves in the lower atmosphere. The energy of this, planetary-sized wave came up from the lower atmosphere over the Himalayas and the Tibetan plateau and broke into the stratosphere, causing a strong sudden warming. It is very fast abolished strong cyclonic Read more [...]

A series of freezing rain in the Norwegian archipelago of Svalbard has led to an almost simultaneous decrease in the number of large herbivores to record low levels.A series of freezing rain in the Norwegian archipelago of Svalbard has led to an almost simultaneous decrease in the number of large herbivores to record low levels, indicating a very high vulnerability of arctic ecosystems to climate change and their accompanying weather events, according to an article published in the journal Science.

Atmospheric precipitation in the solid state is the prerogative of mainly temperate latitudes. Heavy snowfall in this latitude cyclones occur when, emerging at polar fronts. They have large reserves of water, which as a result of falls in the middle latitudes.But it does happen so that the trajectory of the wet and very powerful Barik-circulation formations change. And then they splash out all their unspent energy in the form of snow at the subtropical or tropical. Just a snow collapse happened during the second half of last week, when heavy snow and blizzards have covered the country of Read more [...]
"There is a paradox - a warming, which is characteristic of the world becomes more snow. This is in large areas of Siberia, where the snow more than it was one or two decades ago," - said the director of the Institute of Geography, Russian Academy of Sciences Vladimir Kotlyakov.Global climate change leads to the growth of the snow cover in the Northern Hemisphere and in Siberia, said on Thursday the director of the Institute of Geography RAS Vladimir Kotlyakov, speaking at the World Forum of snow."There is a paradox - a warming, which is characteristic of the world becomes more snow.
