中文摘要：Explosive cyclones(ECs)occur frequently over the Kuroshio/Kuroshio Extension region.The most rapidly intensified EC over the Kuroshio/Kuroshio Extension region during the 42 years(1979-2020)of cold seasons(October-April)was studied to reveal the variations of the key factors at different explosive-developing stages.This EC had weak low-level baroclinicity,mid-level cyclonic-vorticity advection,and strong low-level water vapor convergence at the initial explosive-developing stage.The low-level baroclinicity and mid-level cyclonic-vorticity advection increased substantially during the maximum-deepening-rate stage.The diagnostic analyses using the Zwack-Okossi equation showed that diabatic heating was the main contributor to the initial rapid intensification of this EC.The cyclonic-vorticity advection and warm-air advection enhanced rapidly in the middle and upper troposphere and contributed to the maximum rapid intensification,whereas the diabatic heating weakened slightly in the mid-low troposphere.The relative contribution of the diabatic heating decreased from the initial explosive-developing stage to the maximum-deepening-rate stage due to the enhancement of other factors(the cyclonic-vorticity advection and warm-air advection).Furthermore,the physical factors contributing to this EC varied with the explosive-developing stage.The non-key factors at the initial explosive-developing stage need attention to forecast the rapid intensification.

外文摘要：Explosive cyclones (ECs) occur frequently over the Kuroshio/Kuroshio Extension region. The most rapidly intensified EC over the Kuroshio/Kuroshio Extension region during the 42 years (1979-2020) of cold seasons (October-April) was studied to reveal the variations of the key factors at different explosive-developing stages. This EC had weak low-level baroclinicity, mid-level cyclonic-vorticity advection, and strong low-level water vapor convergence at the initial explosive-developing stage. The low-level baroclinicity and mid-level cyclonic-vorticity advection increased substantially during the maximum-deepening-rate stage. The diagnostic analyses using the Zwack-Okossi equation showed that diabatic heating was the main contributor to the initial rapid intensification of this EC. The cyclonic-vorticity advection and warm-air advection enhanced rapidly in the middle and upper troposphere and contributed to the maximum rapid intensification, whereas the diabatic heating weakened slightly in the mid-low troposphere. The relative contribution of the diabatic heating decreased from the initial explosive-developing stage to the maximum-deepening-rate stage due to the enhancement of other factors (the cyclonic-vorticity advection and warm-air advection). Furthermore, the physical factors contributing to this EC varied with the explosive-developing stage. The non-key factors at the initial explosive-developing stage need attention to forecast the rapid intensification.
