A three-dimensional cloud model was used to characterize the dominant influence of the environment on the Space Shuttle exhaust cloud. The model was modified to accept the actual heat and moisture from rocket exhausts and deluge water as initial conditions. An upper-air sounding determined the ambient atmosphere in which the cloud could : J. A. Zak and C. Chen. cloud of hot, buoyant exhaust products near the ground level, which subsequently rises and entrains ambient air until the temperature and density of the cloud reach an approximate equilibrium with ambient conditions. The United States (US) space activities are conducted by the military personnel (Air Force) and civilians (NASA). Figure 1: Conceptual illustration of cloud formation (source), “cloud-rise” and atmospheric dispersion of the cloud (Nyman, ). A multilayer model to simulate rocket exhaust clouds J. The cloud-resolving model used in this study is a modified version of the System for Atmospheric Modeling (SAM) cloud-resolving model (Khairoutdinov and Randall ).The version used here includes all updates and corrections to this model up through version but does not include the two-moment Morrison microphysical scheme that has been added recently (starting with version ).Cited by: 8.

In our method, clouds are generated by simulating the cloud formation using a scheme employing CML. The simulation space is subdivided into three-dimensional lattices. Fig. 2 shows our system for cloud modeling/rendering. First ly, the user specifies the types of clouds desired and the conditions for the simulation. Some collective nouns for clouds are: a scurry of clouds a souffle of clouds a bank of clouds. The noun cloud is a collective noun for: a cloud of bats a cloud of blackbirds a cloud of flies a.   This study describes and demonstrates a new method for identifying deficiencies in how cloud processes are represented in large-scale models. Kilometer-scale-resolving cloud radar observations and cloud-resolving model (CRM) simulations were used to evaluate the representation of cirrus clouds in the single-column model (SCM) version of the National Centers for Environmental Cited by: A. Bouthors & F. Neyret / Modeling clouds shape Considering that cloud shape is simply the result of the air movement, other possible approaches consist in simulating the uid dynamics [FSJ01, HBSL03] or an animated system of particles [Ney03]. Our model is based on particles (or blobs) associated to an.
