摘要
将阻塞过程中的大气运动流场分解为正、斜压流场 ,研究了它们在乌拉尔山偶极型阻塞个例中的演变特征。揭示了正、斜压流场的演变及相互转换所激发的阻塞生命史的全过程。
The atmospheric flow is divided into barotropic and baroclinic flow fields in a dipole blocking case over the Ural mountains.Investigated are the evolution features of barotropic and baroclinic flow fields and the lifespan of the blocking case which is excited by the interchange between barotropic and baroclinic flow fields.
