Weather visualizations for the Olympics:
Clouds and surface heat index & winds
You can look at RAMS output at eight km resolution computed for June 20,
1996. Each example is accompanied with an in-line image. Click on the image
to see a full-size 24-bit image of the same data. There is an MPEG animation
for each example, and a corresponding VRML geometry.
Output at eight km resolution over the entire Olympics domain is illustrated.
An isosurface of cloud water density is shown with pseudo-color filled
contours of heat index, which are warped vertically by local topography.
Winds are shown as a set of flags, whose direction is that of the surface
wind velocity, and pseudo-colored by wind speed. A 68-frame
MPEG animation will illustrate these techniques and data. You can watch
clouds form over the southern Appalachian Mountains. Click on the image
to see a full-size 24-bit image of the same data. You can also download
a VRML model corresponding to the still image.

An isosurface of cloud water density is shown with pseudo-color filled

Winds are shown as a set of streamlines with directional arrows indicating
surface wind velocity, and pseudo-colored by wind speed. A 40-frame
MPEG animation of this single time step rotated in a westerly direction
will give you a sense of the local topography. You can also download
a VRML model corresponding to the still image and animation.
Now you can look at the next set of examples.
You can see additional images and
learn more about this project, and the visualization work being done.
You can learn more the regional weather model and the parallelized
implementation on an IBM SP2.
