NASA Aircraft Captures Windy Details in Hurricane's Ups and Downs

A vertical slice through the center of Hurricane Dennis shows the rainfall structure across the entire storm, as measured by NASA's ER-2 Doppler radar on July 9, 2005. Warm colors indicate the presence of heavy rainfall and ice within the storm while cool colors show lighter rain. The feature at about 110 kilometers (68 miles) is an intense cloud called a "hot tower" with strong winds throughout the core. The approximate location of the eye is marked by slanted black lines.
