Choi-wan's profile

This cross-section of Super Typhoon Choi-wan reminded me (again) that I love subscribing to NASA's Earth Observatory.

The top picture is neat, but I'd never seen anything like the blue profile below it. According to NASA, the Cloudsat satellite flew over Choi-wan about one minute after the photo was taken by NASA's Aqua satellite and took radar images of the clouds. The dark grey line in the photo shows Cloudsat's path. You can clearly see there are no clouds in the eye, which is surrounded by clouds climbing more than 15 kilometers.

Taken the morning of September 15, right after Choi-wan became a super typhoon. Saipan's probably about 200 km south of the eye.

Whew!
