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