  • Based on the observational facts of seasonal abnormality of the west-pacifc subtropical high, considering a limited zonal belt under 500 hPa layer of north pacific subtropical area in summer,a kind of atmospheric solitary wave is found by applying a nonlinear shallow water model. The excitation, maintenance and propagation of this wave are closely correlated with the activity of middle-/east-pacific subtropical high. By discussing the propagation characters and computing the model atmospheric eigenvalue of the solitary wave, it is found that the route and range both the solitary wave and the atmospheric potential high center are comparatively identical in north-pacific subtropical area. The middle-/east-pacific subtropical high location/intensity. s normal or abnormal adjustment can possibly induce the west-pacific subtropical high being a corresponding variation or abnormity through the propagation mechanism of the solitary wave.
