%X By a nondivergent barotropic vorticity equation,the nonlinear critical layer is simulated. The results show that in the nonlinear critical layer,a phenomenon of "Kelvin cat's eyes" occurs in the field of stream function,having a stream field of anticyclonic circulation.The temporal and spatial scale,eastward moving and shape changing of the "cat's eye" are similar to those of the subtropical high.It is then possible that "Kelvin cat's eyes" produced by the nonlinear critical layer is a new physical mechanism generating the subtropical high in the vicinity of the interface betWeen zonal easterlies and westerlies.
