LOCAL ENERGETICS ON EXPLOSIVE DEVELOPMENT OF EXTRATROPICAL MARINE CYCLONE

<正> Local energetics on explosive development of extratropical marine cyclone was proposed and adiagnosis of the representative cases was performed from local balance,net volume integrationbudget and vertical distribution using the derived eddy kinetic energy equation and eddy availablepotential energy equation.The results revealed that three primary scenarios are responsible for therapid growth of eddy kinetic energy and explosive cyclogenesis,and that a primary explosivedevelopment mechanism is the enhanced baroclinic instability by eddy heat transport and eddydiabatic heating,and that the explosive eyclogenesis is essentially a product of the peculiarclimatological background bearing strong thermal difference in cold season and its conversionpotential.
