【摘要】 本文对正压涡旋上的不稳定问题作了讨论，给出了刚性旋转涡块失稳的研究结果。研究表明，这种情况下依边界条件的不同，可有两类不稳定波动发生，在热带气旋的特定部位，有与该理论分析相一致的波动存在。更多还原

【Abstract】 In this paper the unstability in a barotropic vortex is discussed. The unstable condition of the vortex block of rigid rotation is given. It is shown that unstable waves of two kinds can be generated by different boundary conditions. There are the identical waves with theoretical analyses in a specified position of a tropical cyclone.更多还原
