Abstract
In this chapter, interaction between water and ice clouds is examined through the analysis of tendency of a cloud ratio. The cloud ratio is defined as the ratio of ice water path to liquid water path. The tendency equation of the cloud ratio is derived from prognostic equations of mixing ratios of five cloud hydrometeors. The tendency of the cloud ratio is associated with conversion between the ice and liquid water paths, condensation and depositions, the evaporation of raindrops and rainfall. The cloud ratio is also used to develop a new rainfall separation method for studying structures of precipitation systems. The new rainfall partitioning method is compared to previous separation technique with the magnitude of rain rate through the analysis of cloud microphysical budgets associated with convective and stratiform rainfall.
