Observations o fpolar stratospheric clouds over Murmansk in January-February 2010 Peninsula at this time has been fixed also by the American space satellite "EarthProbe" < http://toms.gsfc.nasa.gov/eptoms/epsat.html> . Later, in 2007, in Hibinskie mountains connection of deep degassing with gravity influence of the Moon and the Sun was found out. The main function of hydrogen at formation of stratospheric clouds is generation of water. Water is formed at direct influence of hydrogen on ozone, and also during its returning from lower thermosphere as a product of burning, as water vapor. It is theoretically established, that at heights of 120-200 km there is a spontaneous ignition and burning out of hydrogen [Nikolaev and Fomin, 1997]. Water vapor formed at combustion o f hydrogen falls down to the heights of the tropopause (10-15 km). Under certain conditions water vapor at the heights of the mesosphere and the stratosphere can turn to the smallest pieces of ice which amount is enough for formation of noctilucent and nacreous clouds. During burning of hydrogen also atomic oxygen is formed, which combining with molecular oxygen turns to ozone. Capacity of such source of ozone is proportional to the contents of molecular hydrogen in the lower layers of the atmosphere. It apparently will allow looking at the reasons of occurrence of ozone holes in a new fashion. For formation of stratospheric clouds, besides other conditions, the most important and necessary condition is low temperatures. One of the mechanisms of cooling of the atmosphere at the stratospheric heights is connected with a flow of airstreams over the big obstacles (mountain ridges, etc.). At such passage oscillations of air are formed. In the case when the airstream operates constantly during some time it forms steady waves from the lee side of mountains. These leeward waves represent streams of waves, which rise and fall several times. In the areas where they rise, air extends and cools. Above Scandinavia frequently the western winds saturated with moisture from Atlantic Ocean blow. Feature of location of the Scandinavian mountains plays a barrier role regarding to the western winds. They block the western winds, creating leeward oscillatory movements that lead to local cooling of the area of the atmosphere above mountains and thus conditions for formation of polar stratospheric clouds are created. Conclusions Results of visual and photographic observations of the polar stratospheric clouds in Murmansk in January-February 2010 are presented. Based on the concept of equivalent radius o f the Earth the height of the lower border of cloud field is determined. Assumptions of possible dependence between occurrence of nacreous clouds and some geophysical phenomena are made. Conditions of formation of stratospheric clouds and their influence on the total content of ozone in the atmosphere are discussed. Scientific researches of these clouds are very important for the best understanding of the processes taking part in the stratosphere. In fact, the stratosphere plays an important role in our life. First, here is the ozone layer, which protects us from destructive influence of solar radiation. Second, influence of the dynamic processes taking part in the stratosphere affects also on troposphere dynamics. Researches show, that circulating processes in the stratosphere with the certain delay influence on troposphere circulation. It can serve as a key to creation of more exact techniques of long-term forecasting weather anomalies. Researches of nacreous clouds will allow scientists to solve riddles of processes of condensation water vapor, conditions of its existence and to determine character and speed of movements of air at the stratosphere.
