| Abstract: | Local energetics on explosive development of extratropical marine cyclone was proposed and a diagnosis of the representative cases was performed from local balance,net volume integration budget and vertical distribution using the derived eddy kinetic energy equation and eddy available potential energy equation.The results revealed that three primary scenarios are responsible for the rapid growth of eddy kinetic energy and explosive cyclogenesis,and that a primary explosive development mechanism is the enhanced baroclinic instability by eddy heat transport and eddy diabatic heating,and that the explosive eyclogenesis is essentially a product of the peculiar climatological background bearing strong thermal difference in cold season and its conversion potential. |
