THE MOMENT: Hurricane Katrina rages again in the Gulf of Mexico in this visualization created by researchers at Louisiana State University. The lines indicate the counterclockwise wind rotation that drove gulf waters onto the shore; their color shows air temperature (yellow is warmest, followed by red and blue, with coolest in white). The background color depicts sea elevation, with the intense blue near shore marking the storm surge.
THE SHOT: Scientists at LSU’s Center for Computation & Technology used the university’s supercomputer to integrate wind, temperature, and sea surge simulations with satellite data.
