Weather visualizations for the Olympics:
Thunderstorms over Georgia
You can look at RAMS output at eight km resolution computed for July 13
and 15, 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.
Output at eight km resolution over the entire Olympics domain. Cloud
water density is shown as isosurfaces with surface precipitation shown
as continuous pseudo-color terrain. Cloud reflectivity corresponding to
internal rain shafts is shown as cyan isosurfaces. Thunderstorms can be
seen where the rain shafts are visible and blue "puddles" of rainfall on
the surface. A 55-frame MPEG animation
shows the formation of these thunderstorms. The model predicted the thunderstorms
rolling through the greater Atlanta area about six hours before they actually
occurred!
Output at eight km resolution over the entire Olympics domain. Cloud
water density is shown as isosurfaces with surface precipitation shown
as continuous pseudo-color terrain. Cloud reflectivity corresponding to
internal rain shafts is shown as cyan isosurfaces. Surface winds are shown
as pseudo-colored streamlines with directional arrows. Location of Olympic
venue sites are marked with three-dimensional icons. Thunderstorms can
be seen where the rain shafts are visible and blue "puddles" of rainfall
on the surface over Northern Georgia and western North Carolina. You can
view the region at this particular time through four animations.
A 60-frame MPEG animation shows
the area by slowing rotating in an easterly direction.
A 60-frame MPEG animation shows
the area by slowing rotating in an westerly direction.
An 110-frame MPEG animation shows
the area by flying over major venue sites.
A 60-frame MPEG animation shows
the area by zooming into the central portion of the region around Atlanta.
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 SP-2.
