Atmospheric ice particles play crucial roles in cloud and storm dynamics, atmospheric chemistry, climatological processes, and other atmospheric processes. Ice Microdynamics introduces the elementary physics and dynamics of atmospheric ice particles in clouds; subsequent sections explain their formation from water vapor, why ice crystal shape and concentration in cirrus clouds influence the heating of air, and describe how ice crystals cleanse the atmosphere by scavenging aerosol particles. Pao Wang's lucid writing style will appeal to atmospheric scientists, climatologists, and meteorologists with an interest in understanding the role of ice particles in the atmosphere of our planet.
