In this section, we present a summary of the developed cloud convection model that incorporates condensations of H2O and NH3 and production reaction of NH4SH. The system is two-dimensional (2D) and in the horizontal and vertical directions only. The basic equations of the model are based on the quasi-compressible system [1] and conservation equations of all of the major condensible species. The cloud microphysics and the effect of subgrid turbulence are implemented by the parameterization schemes of Kessler (1969) [2] and Klemp and Wilhelmson (1978) [1], respectively. The basic equations are discretized using the finite difference method in space, and time integration is performed using the time-splitting method [1] in which the acoustic mode and the other mode are integrated using different time steps. A visualization technique that can be called an "RGB composite" is employed in order to visualize multiple composition clouds in a single cloud image. In this technique, the distribution of H2O, NH3, and NH4SH cloud mixing ratios are represented using red, green, and blue color tones, respectively, and that of multi-composition cloud is represented using the superposed color of the three.
