Weather visualizations for the Olympics:
Hurricane Bertha off the Georgia Coast
You can look at RAMS output at eight km resolution computed for July 11
and 12, 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 for July
11. Cloud water density is shown as isosurfaces with surface temperature
shown as continuous pseudo-color terrain. Surface winds are shown with
vector arrows, pseudo-colored by speed. The outer fringes of Hurricane
Bertha are visible near the Georgia coast. A 73-frame
MPEG animation shows Bertha moving slowly off the coast. You can also
see the formation of orographically influenced clouds over the southern
Appalachian mountains.
Output at eight km resolution over the entire Olympics domain for the
next day. Cloud water density is shown as isosurfaces with surface humidity
shown as continuous pseudo-color terrain. Surface winds are shown with
vector arrows, pseudo-colored by speed. The outer fringes of Hurricane
Bertha are visible near the Georgia coast. A 73-frame
MPEG animation shows Bertha moving slowly off the coast. You can also
see the formation of orographically influenced clouds over the southern
Appalachian mountains as drier air moves into the region from the west.
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.
