摘要: | A new estimate of the wind energy associated with a tropical cyclone (TC), along with the revised accumulated cyclone energy (RACE) index, is introduced in this paper. In contrast to the conventional means employed in computing the ACE index, in which the wind energy is measured at the radius of maximum wind, the new estimate considers the mean wind energy averaged over a circular area based on the modified Rankine vortex structure. An examination of the seasonal TC activity using the JTWC best-track records over the western North Pacific suggests that, as long as there is a strong variability in TC activity (characterized by a substantial year-to-year variability in the RACE/ACE time series), employing a more precise estimate of the cyclone wind energy is not just physically reasonable, it can also be practically useful.
