Interesting weather in Hawaii -
an animation of IR images during a frontal passage December 4-6, 2007
Interesting weather on Mars! -
a NASA animation of Mars Spirit Rover images showing several dust
devils racing across the surface. Images were taken on
July 13, 2005. Real elapsed time in seconds is shown in the
lower left corner

Here is an attempt to visualize the polar vortex as simulated in the
SKYHI General Circulation Model. What is shown is an instantaneous
of a surface that surrounds the air with low nitrous oxide concentration
(in this case low relative to the mean value at each horizontal level).
What you see is a Northern Hemisphere projection with the vertical scale
marked in potential temperature. The vertical extent shown is from about
10 km to 45 km. The main vase-like sheath outlines the polar vortex,
the ribbons wrapping around the vortex represent air that has recently
from the vortex. (for more details)

a photo taken while an animation produced in collaboration
with the Bishop Museum in Honolulu is projected onto
a large sphere in their "Science on the Sphere" exhibit hall.
In 2006 & 2007 I participated in Hawaii Public Radio
shows featuring discussions of environmental issues and research
efforts relevant to Hawaii.
