| 摘 要： | In this paper,the effects of first and second meridional derivative(i.e.h_s~(?),d~2f/dy~2,(?)″)of the Coriolisparameter,Westerly profile and topography structure on ray routes are qualitatively analysed by use of a sim-plified mathematical model.The analysis indicates that the second derivatives of the above relevant factors playan important role in the formation of great circle route.A profile of west wind similar to the real atmospheremay result in a“sine wave pattern”of ray.The effects of west wind shear,β factor and the slope of topographyon the scale of radius of great circle,critical latitude of rays ard the amplitude of wave train of teleconnection aroalso discussed.Additionally,the characters of critical velocity profile for meridionally trapped wave are men-tioned.
