对发生在北太平洋西部中高纬度海洋上的两个爆发性气旋和一个非爆发性气旋进行了非地转ω方程诊断分析.认为强的温度平流、涡度平流、位涡平流和凝结潜热释放是使气旋爆发性发展的主要因子,爆发性气旋发展过程是一特殊的斜压过程,存在着某种自我激发的机制.非爆发性气旋不但其发展因子(如涡度平流、温度平流、位涡平流、潜热释放等)在量的方面较爆发性气旋要小,自我激发性机制表现得也不明显.爆发性气旋与非爆发性气旋的发展,不但强度上存在量的差异,而且其发展机制也存在质的差异.
The non-geostationary ω equations of two explosive cyclones and one non-explosive cyclone occurring in the middle and high latitudes of the western North Pacific have been diagnosed and analyzed.It is considered that the strong advection, eddy advection, potential eddy advection and latent heat of condensation Is the main factor that causes the cyclone to develop explosively.The development process of the explosive cyclone is a special baroclinic process with some self-excitation mechanism.Non-explosive cyclone not only has its development factors such as vorticity advection, temperature advection, Vortex advection, latent heat release, etc.) are smaller than explosive cyclones in terms of quantity, and their self-excitation mechanism is not obvious. The development of explosive cyclones and non-explosive cyclones is not only different in intensity, but also its development There are also qualitative differences in mechanisms.
