[FRIAM] Simulating Cloud Dynamics at Interactive Rates

[Stephen Guerin]

Nick, you should appreciate the video associated with the paper in this
link. We are considering something like this to help interpolate fire
plumes from our work with alertwildfire.org cameras.

Abstract
The complex interplay of a number of physical and meteorological phenomena
makes simulating clouds a challenging and open research problem. We explore
a physically accurate model for simulating clouds and the dynamics of their
transitions. We propose first-principle formulations for computing buoyancy
and air pressure that allow us to simulate the variations of atmospheric
density and varying temperature gradients. Our simulation allows us to
model various cloud types, such as cumulus, stratus, and stratoscumulus,
and their realistic formations caused by changes in the atmosphere.
Moreover, we are able to simulate large-scale cloud super cells – clusters
of cumulonimbus formations – that are commonly present during
thunderstorms. To enable the efficient exploration of these stormscapes, we
propose a lightweight set of high-level parameters that allow us to
intuitively explore cloud formations and dynamics. Our method allows us to
simulate cloud formations of up to about 20km×20km extents at interactive
rates. We explore the capabilities of physically accurate and yet
interactive cloud simulations by showing numerous examples and by coupling
our model with atmosphere measurements of real-time weather services to
simulate cloud formations in the now. Finally, we quantitatively assess our
model with cloud fraction profiles, a common measure for comparing cloud
types.
