Analysis of experimental data demonstrates that cosmic ray enhancement stimulates an increase of atmospheric aerosols and cloudiness. The study of solar proton events (SPE) has shown that during SPE one can observe increase in aerosol density by 1.2-1.4 times at 12-18 km altitudes. Such variations of aerosol density can be detected on global scale. Aerosol variations cause changes in integral atmospheric transparency which during disturbed periods can reach 5-6%. The atmospheric integral transparency variations are not less during the solar cycle on account of galactic cosmic ray variations. Atmospheric transparency variations creating the so-called "grey filter" for solar radiation should lead to surface temperature variations. During the periods of low solar activity under the influence of enhanced galactic cosmic ray fluxes, the density of the "grey filter" should increase and cause a decrease in surface temperatures, correspondingly. In frame of the physical mechanism considered the connection between solar cycle durations and surface temperature variations can be explained. In addition, one can understand the physical reason for the "Little Ice Age" appearance during Maunder minimum of solar activity, 2400 years periodicity of climatic processes, strong influence of the decrease in main geomagnetic field intensity on the development of Ice Age and Global Cooling.
对实验数据的分析表明，宇宙射线增强会刺激大气气溶胶和云量增加。对太阳质子事件（SPE）的研究表明，在太阳质子事件期间，在12至18公里高度处可观测到气溶胶密度增加1.2至1.4倍。这种气溶胶密度变化在全球范围内都能被检测到。气溶胶变化会导致大气整体透明度发生变化，在扰动时期，这种变化可达5%至6%。由于银河宇宙射线的变化，在太阳活动周期内大气整体透明度的变化也不小。大气透明度的变化为太阳辐射创造了所谓的“灰色滤镜”，这应该会导致地表温度变化。在太阳活动低的时期，在增强的银河宇宙射线通量的影响下，“灰色滤镜”的密度应该会增加，相应地导致地表温度下降。在所考虑的物理机制框架内，可以解释太阳活动周期持续时间与地表温度变化之间的联系。此外，人们可以理解在太阳活动蒙德极小期出现“小冰期”的物理原因、气候过程的2400年周期性、主地磁场强度下降对冰河时代和全球变冷发展的强烈影响。
