Description



Cumulous cloud development is simulated using fractal ellipsoids to model the clouds. The ellipsoids are positioned and scaled by a heuristic dynamic model based on the "parcel" theory, which describes cloud development in terms of air bubbles heated by external sources such as radiated terrain heat. As a bubble of air is heated, it expands and rises into the cooler atmosphere above until it reaches an altitude where moistures condenses to form a cloud. The condensation releases heat within the bubble and the process continues to a point of equilibrium.

Technical Information

This simulation was performed using proprietary software written in Fortran running on a Silicon Graphics Personal IRIS 4D/25G workstation.
