Book Description
A one-dimensional mathematical model of the growth of ice crystals in supercooled clouds was examined in detail and a sensitivity analysis was performed. Critical parameters include seeding rate, temperature, cloud depth, liquid water content, drop size, and updraft velocities. Calculations were compared with experimental observations made during a stratus seeding field program conducted in Northern Michigan in 1977. Substituting reasonable values of cloud physics parameters and using known values of the seeding rates, minimum temperatures, and cloud depth, reasonable agreement between theoretical and observed rates of cloud dissipation was obtained.

The Microphysics of Ice Clouds
Author: Rosemary M. Dyer
Publisher:
ISBN:
Category : Atmospheric physics
Languages : en
Pages : 44
Book Description
Published results of observations of crystal habits, particle sizes and numbers of ice particles in clouds are summarized and discussed. There are systematic variations with cloud type, and in some instances, with cloud age and location within a cloud system. However, the body of data available is insufficient to formulate a climatology of ice cloud microphysics. The several measurement techniques in current use are evaluated, as are some of the techniques now under consideration for future use. The particle enhancement observed on some occasions is discussed, and the various theories accounting for it presented. Finally, recommendations are made concerning future field programs and theoretical studies required before accurate predictions of the ice cloud microphysical environment can be made. (Author).
