We propose a new atmospheric model based on first-principles for the simulation of
clouds. Our approach is able to simulate the realistic formation of various cloud types,
such as cumulus, stratus, stratocumulus, their temporal evolution, and transitions
between cloud types. Moreover, we are able to model strongly rotating thunderstorms
known as supercells. Our method allows us to simulate cloud formations of up to
about 20 km 20 km at interactive rates. For the intuitive exploration, we identified a
light-weight parameter set to interactively explore cloud formations. We demonstrate
that our model can be coupled with data from real-time weather services to simulate
cloud formations in the now.
Moreover, we present a novel approach for the simulation of wildfires. Our model
is able to realistically capture the combustion process of trees, heat transfer with the
environment and fire propagation between trees. We demonstrate that our approach
is capable of realistically simulating the propagation of fire through entire ecosystems
with varying vegetation occupancy. We integrated our atmospheric model which
allows us to simulated clouds emerging from the evaporation of water from burning
trees leading to complex so called flammagenitus patterns which are usually observed
over wildfires. Our system runs at interactive rates which enables the exploration of
wildfires in different environments.
