摘要

The satellite images received in the Institute were used to research the influencing of Forbush-effect on change of clouds above the Yakutia. The obtained results demonstrate, that the influencing of variations of the cosmic rays on clouds is various depending on the level of the auroral activity and are agreeing with the earlier obtained results of the other explorers. It was shown that the thunderstorm activity anti-correlates with number of sun-spots in 11-years cycle with a factor 0,83. Also it is known that the long-term variations of the humidity and clouds in scale of northern hemisphere anti-correlate with solar activity. However, in local scale the behavior of the humidity and clouds depend on a" latitude and orography of terrain, and is being determined by change of trajectories of atmospheric cyclones and anticyclones. In the Yakutia the quantity and the areas of forest fires are determined mainly by the low level of the humidity during the second half of summer. The outcomes of biological researches of old trees and data presented by "Avialesokhrana" (anti-wildfire service) demonstrate that the forest fires were in past with periodicity roughly 10 and 22 years.
