英文摘要: This study evaluates the potential of a proposed technique in using satellite-borne radiometer measurements and weather analyses to estimate the intensity of tropical cyclones. This theory shows that intensity is essentially directly related to the temperature deficit of cloud top versus sea surface, and the surplus in saturation entropy in the eyewall versus its surroundings. The eyewall entropy estimate comes from measurements of cloud top temperature and pressure, and the analysis provides the environmental saturation entropy. An Observing Systems Simulation Experiment was conducted, and the results were compared to those from previous studies using cloud-profiling radar altimetry measurements. The use of cloud top pressure measurements may produce more accurate results. Inherent challenges still require caution in considering operational implementation. Key Points A new satellite-borne tropical cyclone intensity is proposed It improves upon sampling and accuracy of past satellite-based methods It could impact future operational application and observing system development ©2013.
