Scientists used pre-storm conditions from an observed F4 tornado
in South Dakota in 2003 to initialize a simulation that produces a
severe supercell storm that produces a powerful tornado and terabytes of
data.
Data driven visualization components reveal the inner-workings of
thesimulation. Interactively filtered streamtubes colored orange when
risingand blue when sinking represent the path of air through the storm.
A swirling mass of red spheres in the low pressure tornado vortex
delineates the developing tornado.
On the ground plane, tilting cones represent wind speed and direction.
Colored by temperature, they show a surface boundary where warm and cold
air interact at the tornado's base.
This visualization represents one hour of storm evolution. Large scale
thunderstorm simulations have only recently produced small scale
tornadic features as seen here.
