In these days of January frosty anticyclone put everything upside down. In the south of the European part of severe frosts, and to the north of anomalously warm. The reason cyclones moving through the water areas of the Arctic seas, do not miss the cold air, and the mean daily temperature on the eve of the north-east of European Russia was above normal by 12-16 degrees.
In addition to heat, cyclones are snowfall, wind increase, raising the snowstorm. And in the area of inclement weather, first of all, are the extreme northern regions of the Republic of Komi Vorkuta, Inta, Pechora, Usinsk.

As noted above, the dominant in the temperate latitudes of the northern hemisphere Western transport is one of the most important factors in the formation of climate KhMAO along with the influence of the continent. The combination of these factors, as well as the influence of topography give the atmospheric circulation over KhMAO some peculiar features that are not typical of more western and more eastern parts of Russia, and lead, in particular, to a large variability of the weather. Under the influence of the Ural mountains change their direction and enhanced cold surround invasion, and under Read more [...]
The amount and distribution of precipitation is defined as features of atmospheric circulation, and the nature of the terrain. Zonal distribution of precipitation depends on the activity of the frontal cyclones. On KMAO falls less number of precipitation, compared to the ETP, which is associated with an increase in continentality, ie weakening of cyclonic activity, decreasing clouds and some reduction in the moisture content of the air, as the summer and winter are dominated Arctic air mass origin. Also the influence of the Ural mountain range, mainly in the general decrease in rainfall Read more [...]
The frequency of destructive typhoons, wind speed at the center of more than 200 km / h, by the end of 2010 increased by 10 times. This is the scientific forecast of the Japan Meteorological Agency. The cause of the damaging winds will be the global climate change and the rise in water temperature of the oceans.
A team led by Ouchi Katsuoshi created supercomputer model that takes into account all the modern climate trends, laid the forecast data and information about the atmospheric state of the Earth. The whole planet was conditionally divided into sectors by 14? kilometers.
Based on these Read more [...]
on may 11.The drought this year, the Mexicans will remember for a long time, such a heat in Mexico has not been for decades. The temperature exceeds 50 degrees in the shade.
For several months now in the country there is drought in the Central and Northern part of Mexico for a long period of no rain. The earth was dry and cracked, farmland affected by drought and high temperatures.
But salvation is at hand after a few weeks you should begin the rainy season and the season of tropical cyclones coming from the Gulf of Mexico.
In order to correct the effects of drought, require only moderate Read more [...]
November 18, 2013. Powerful cyclones «Saint Jude» and «The Haiyang» have incited the idea that the Earth's climate irreversibly deteriorated. But is it really? Deputy Director of the situational center of the hydrometeorological center of Russia Yuri Varakin believes that the emergence of these cyclones is not unusual. And hence the climate of the Earth until everything is in order.
Indeed, at first glance it may seem that Earth's climate is something strange. No sooner had the people of Northern Europe to recover after the storm «Saint Jude» caused great Read more [...]
Tropical cyclone, Malakas 21.09.10 @ NASA/JPL, Ed Olsen
September — the most favorable time for the development of tropical cyclones. These destructive whirlwinds eat warm ocean, namely in September, the surface water temperature reaches the maximum value. One tropical cyclone, «Lisa», crisscrossing the vast Atlantic. But he is not yet strong, and far from the coast. Interesting cyclones of the Pacific ocean.
One of them, «Malakas» goes to Japan. Now the winds near its center reaches 25 m/s But it's a young whirlwind, it is amplified, and after a few days the Read more [...]
on January 17. The number of tropical cyclones that hit the Russian far East in the past year, has reached its highest in 30 years, equalling the record of 1981, according to the hydrometeorological center of the Russian Federation.
«Exit tropical and ex-tropical cyclones in the far East of Russia doesn't happen every year, on average, per year there is one or two of the cyclone. Over the past 40 years the greatest number of tropical cyclones recorded in 1981 — five cyclones. In 2011, this record was repeated», — the message says.
In General on the planet last 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 [...]

The South-Eastern United States has experienced a growing number of large storm surges from tropical storms since 1923.
on 15 October. Tropical cyclones in the present was more than in the past, or it seems to us due to the fact that now we often hear about them, as the media began to pay more attention to this, and now that the cyclones are easier to detect using satellites? Held at the Niels Bohr Institute studies clearly show that there is a growing tendency of the formation of cyclones, if the climate becomes warmer than it was in the previous few years. The results of this study published Read more [...]
Tropical storm \"sandy\" 23 October 2012. © NASA
on 3 November. While Americans and Canadians assess the damage and estimate the losses from the excesses of \"sandy\", we will try to understand the terminology of the cyclonic eddies. After all, originally a tropical cyclone sandy was transformed into the extratropical cyclone and covered the East coast of the USA and Canada in the new quality. The thing is that in tropical and extratropical cyclones completely different physics: first appear in the tropics over very warm water (not less than 27 °C) and \"eat\" allocating a huge amount of heat Read more [...]

February 8, 2013. This winter we have heard many times in the weather that we are approaching the next active cyclone, which is going to fill all the snow and turn roads and streets impassable snowdrifts. Cyclones, deliberately overwhelming us with snow, come with relatively warm and also water underlying surface. Such properties are characterized by the waters of the North Atlantic, thanks to the Gulf stream, and the waters of the Mediterranean sea, generally located at subtropical latitudes. Therefore, people from those places possess a vast reservoir of moisture, which, in fact, goes first Read more [...]

Tropical cyclones, depending on the intensity and the life cycle can be divided into 4 types :
1) tropical disturbance (tropical disturbance). Poorly defined vortex with low wind speeds (less than 17 ms). On the weather map no closed isobars. Vortex lines traced by the convergence of the current;
2) Tropical Depression (tropical depression). On the weather map are 1-2 closed isobars. Wind force up to 7 on the Beaufort scale (32-38 knots or 17-20 ms) (Annex 4);
3) tropical storms (tropical storm). On the weather map has more than two closed isobars and wind speed of more than 7 points. Read more [...]
Tropical cyclones occur in the tropical and equatorial zones between 22 ° south. sh. and 35 °. sh. except for a narrow equatorial band (2 ° c. S. 2 ° south. lat.).
According to Gray , tropical cyclones in the southern hemisphere occur between 3 and 22 °, and in the northern hemisphere - between 3 and 35 °. In the area of 3-10 ° latitude (both hemispheres) formed 22% of all tropical cyclones. Between 10 and 20 ° latitude occurs 65% of tropical cyclones. North and south of 20 ° is formed only 13% of tropical cyclones.
Thus, most of the tropical cyclones (87%) occurs in the area Read more [...]
