Predicting how a hurricane's intensity will change duing its lifetime is challenging, in part because of difficulties in forecasting how the internal structure of the storm will evolve. Houze et al. (p. 1235; see the Perspective by Willoughby) examine a key component of that process, "eyewall replacement." They document in great detail the eyewall-replacement cycle in Hurricane Rita using high-resolution airborne radar observations of wind speed as well as temperature, humidity, and pressure data, and develop a conceptual model for this process. They also suggest how obtaining specific data on small-scale structure of hurricanes could improve forecasting of intensity changes.
