外文摘要：The inter - comparison?of development?mechanisms of?explosive?cyclones (ECs)?at different?stages over the Japan Sea and Kuroshio/Kuroshio Extension was?examined by case studies and composite statistical analyses based on the ERA5 data?and diagnostic method.?The most rapid intensification?cases over the Japan Sea and Kuroshio/Kuroshio Extension?(referred to as EC1?and EC2, respectively) were?selected for?the diagnostic analyses using the Zwack-Okossi equation. The results?showed?that the?key factors?contributing?to the explosive development?varied?with regions and explosive-developing stages. The?main contributor to?the initial explosive development?was?the warm-air advection?for?EC1?and diabatic heating?for EC2. From the initial?explosive-developing moment to the maximum-deepening-rate moment, the cyclonic-vorticity advection and diabatic heating for EC1?and the cyclonic-vorticity advection?and warm-air advection?for EC2?enhanced?quickly?and contributed?to the maximum explosive development. The order?of the change?for?each factor between the two moments in composite?statistical?analyses (57 ECs over the Japan Sea and 74 ECs over the Kuroshio/Kuroshio Extension)?was?consistent?with the case studies. Moreover, changes of?the cyclonic-vorticity advection?and diabatic heating?for ECs over the Japan Sea and the cyclonic-vorticity advection?and warm-air advection?for ECs over the Kuroshio/Kuroshio Extension?had?significant correlation with the change of the deepening rate, supporting the results of case studies. ? 2022, The Authors.
