Query: Coupled Map Modeling for Cloud Dynamics   A coupled map model for cloud dynamics is proposed, which consists of the
successive operations of the physical processes; buoyancy, diffusion,
viscosity, adiabatic expansion, fall of a droplet by gravity, descent flow
dragged by the falling droplet, and advection. Through extensive simulations,
the phases corresponding to stratus, cumulus, stratocumulus and cumulonimbus
are found, with the change of the ground temperature and the moisture of the
air. They are characterized by order parameters such as the cluster number,
perimeter-to-area ratio of a cloud, and Kolmogorov-Sinai entropy.
