Scientists have simulated the inner workings of lightning "jet dust storms" on Mars, which is a hundred times faster than regular storms and are bombarded with dust high into the atmosphere of the Red Planet.Mars - very dry and dusty place. Storms sometimes cover the entire planet, and orbiters see as persistent dust layers reach great heights (30 º 50 km above the surface). The mechanism of the latter phenomenon is unclear.
High resolution model based on data from the instrument OMEGA, which is located on the satellite Mars Express, helped figure out how thick spherical pocket dust Read more [...]
The first time since the 1970s, the development of events observed and from orbit and from the surface of the Red Planet. None of the rovers while working there was injured.Martian dust storm, followed by a probe Mars Reconnaissance Orbiter watched from last week, led to changes in the atmosphere, seen rovers on the surface of the planet.

18/12/2012 New research shows that Arctic storms should be included in climate models. Although we are more familiar with their tropical "colleagues", arctic storms are polar storms occurring in conjunction with a 9-meter high waves that can sink a small ship. A new study shows that Arctic storms are much more important to the functioning of our climate than previously thought. Geologists have found that polar cyclones have a significant impact on ocean circulation and climate, but are not included in any current climate models. They are important because they affect the "production Read more [...]
Up until the end of October, it was an unremarkable season until the Mid-Atlantic coast of the U.S. did not come out "Sandy" ... Formally, he joined on land not even a hurricane, as it did in August, "Isaac," which devastated southeast Louisiana and took the lives of seven people. At the same time, "Sandy" has a tremendous force, equal to the energy of five nuclear bombs.

on 4 September. The effects of the powerful storms on the sun today can affect the inhabitants of the Earth. This writes the world media. A few days ago was shining once again flew into a rage and threw a huge flare - length fiery whip, according to experts at NASA reached 800 thousand kilometers.
Scientists were able to capture this process. According to the calculations of astrophysicists, today, the flow of the stellar radiation reaches our planet and can cause a geomagnetic storm. However, overcoming tremendous distance (150 million km), the beam will be scattered and strong will not cause Read more [...]
China to hit the strongest winter storms - meteorologists say that these snowstorms in the country was already 30 years old. Because of the cold weather and blizzards hit 50 thousand. Fallen snow, the most optimistic projections, will lie until March.

Cover with our country in the recent storms and thunderstorms - is just the beginning, the director of the World Wildlife Fund in Latvia Uģis Rotbergs. According to him, the consequences of global warming and climate change will be even more devastating weather events.
Thus, he predicted, Latvia could become a victim of more heat waves and droughts, storms and thunderstorms can be even more powerful and occur more often. Rotbergs recalls that phenomenon, not typical for Latvia before is now happening all the time, for example, a short but heavy rains, when a few minutes pours almost monthly Read more [...]
on January 13. A small town in the English County of Lancashire has covered foam storm. The phenomenon is not so rare, but strikingly beautiful. The wind from the ocean have brought so much foam that town Clive was as if buried under a thick layer of snow. The largest such storms have recently been recorded in Cape town and Australia. Scientists say that such a huge amount of foam is formed from the interaction of strong storms, salt water, and waste products of marine organisms.
We remind readers that at the end of December 2011, in England was already foamy storm. Read more [...]
on August 11. The storm began off the coast of Alaska and went practically throughout the Arctic sea. For the last 34 years, the number of such storms over the North pole, recorded in August, does not exceed eight. Unusual storm called because, as a rule, such atmospheric system pressure of about 964 mbar are in the Arctic only in winter.
According to experts, untimely storms can have a huge impact on the state of the sea ice, causing it to melt at an accelerated pace. The ice under the influence of warm masses willing to split into blocks, which are wind-dispersed in warm latitudes, and there Read more [...]
List of seismic waves would be incomplete if we do not mention about a mysterious form of small waves, largely hindering the work of seismologists, but sometimes bearing and benefit. They regularly recorded around the world continuously, day and night. Because of the small size, this strange "trembling" is called "microseisms".
Microseisms were discovered at the beginning of the birth of instrumental seismology. In 1872, Italian explorer Bertilli decided that the small oscillations of the pendulum are related to changes in atmospheric pressure. And he was right! In 1900, Read more [...]

on July 18. Many climate scientists are conducting research on how climate change will affect individual components of weather, such as clouds, precipitation, the nature of lightning, etc. So, in tel Aviv University found that for every degree of warming in the future will have 10% more lightning during storms than usual.
As shown by the climate model and current examples of worsening cycle of El niño events in Indonesia and South-East Asia, increased intensity of storms will have negative effects and increase the risk of floods, fires, increased cases of power supply interruption and destruction Read more [...]
April 26, 2013. Eastern Scotland once again faced with the problem of dust storms. This time under a layer of sand was quite fertile field where grown barley. However, in 2013, it will not be able to collect even 50% of the harvest, as the field turned into a real sandy beach, covered with several tons of Golden sand, through which young barley shoots will be extremely difficult to break.
For the second time in the last season in the country is similar to the dust storm. Residents, especially farmers from the region of Moray, stunned and extremely concerned about what is happening, because Read more [...]
