Dynamics of Extratropical Explosive Cylcogenesis

气象学家长期以来一直认为 大部分快速增强的气旋的共同特征， 北方半球的热带外地区。 的相互作用 在短波和长波槽中， 高空扰动和地面低压的位置 压力中心，凝结时释放的潜热， 风暴进一步发展是考虑的因素之一 是爆发性气旋形成的关键理论上， 方法，Barcilon教授和Weng博士将使用非线性 两层Eady型模式，研究行星和 热带气旋生成中的天气波及其作用 大尺度演变中的温带气旋 流通

Meteorologists have long appreciated certain salient features common to most of the rapidly intensifying cyclones in the Northern Hemisphere extratropics. The interaction of a traveling short.wave and a long.wave trough, the relative position of the upper.level disturbance and the surface low pressure center, the latent heat released from condensation when the storm is further developed are among the elements considered essential in explosive cyclogenesis. Taking a theoretical approach, Professor Barcilon and Dr. Weng will use a nonlinear two.layer Eady.type model to study the roles of planetary and synoptic waves in extratropical cyclogenesis and the role of extratropical cyclones in the evolution of large.scale circulation.
