Abstract:

Atmospheric thermal convection, including condensation and evaporation, is modeled on the cumulus scale by numerically solving the equations of hydrodynamics and thermodynamics. Appropriate finite-difference equations are derived for both axial and rectilinear symmetry and for two differencing schemes. A mixed Euler-Lagrange method is used. A specific example is discussed, and its computational results are compared with observations made from instrumented aircraft of the Naval Research Laboratory. It is concluded that the model is realistic in many respects, and that it could be a useful adjunct for research in cloud dynamics and cloud physics, particularly in the field of weather modification.
