英文摘要

Typhoon Meranti (2016) underwent extreme rapid intensification (RI) over the western North Pacific (WNP), just before its landfall in Fujian Province, China. In this study, the extreme RI, track, and structures of the inner core and spiral cloud bands of Meranti were simulated, reasonably realistically, using WRF-ARW (the Advanced Research version of the Weather Research and Forecasting model). Firstly, the convective bursts (CBs) and associated microphysical processes were analyzed in detail to evaluate the probable mechanism responsible for the RI of Meranti. The results showed that Meranti experienced RI over the warm ocean with high ocean heat content and decreasing environmental vertical shear. The onset of RI was triggered by CBs, which penetrated the upper troposphere, leading to upper-tropospheric warming and the formation of an upper-level warm core. Diagnosis of the complete Q-vector showed that the CBs of the inner core were jointly triggered by the dynamic forcing of the frontogenesis and the non-adiabatic phase transition process. Further analysis of the heat budget of microphysical processes revealed that the condensation process (accounting for 76.3% of the total heating rate of the warming processes) played a leading role for CBs in the lower and middle troposphere, while the deposition process (accounting for 19% of the total heating rate of the warming processes) was a critical factor of the CBs in the upper level of the troposphere.
