Physics of clouds and aerosols

Lecturer: PhD S.S. Vlasenko (51 hours)

From atmospheric sciences "the Physics of clouds " is one of the most  early and developed, as for  men questions of formation of clouds and precipitations were always vital. "Physics of atmospheric aerosols" as the separate science has developed rather recently. In 50th  the aerosols were investigated basically as potential nucleuses of condensation. The wide development of optical methods of study of the atmosphere has resulted in understanding of importance of a role of aerosols in radiation atmospheric processes. In 70th  the researchers have paid attention to importance of participation of aerosols in atmospheric chemical processes. It is necessary also to note, that the phenomena of the atmospheric electricity for the explanation also require the knowledge of processes of interaction between ions and aerosol particles. All this was resulted in active complex researches of atmospheric aerosols and forming of a science "Physics and chemistry of aero-dispertion systems ", uniting physics of atmospheric aerosols and physics of clouds.
