摘　　要：利用三维半地转模式讨论了春夏秋冬四季基本气流上非线性斜压扰动的发展过程和锋面形成过程。计算结果表明，在四季基本气流上，斜压扰动的发展能产生冷暖锋，扰动的发展以冬季为最强，春季次之，秋季和夏季最弱，相应地，形成的锋也以冬季最强，春季次之，秋夏季最弱，与实际观测比较一致。he development process of nonlinear baroclinic waves and frontogenesis on the mean flows of the four seasons are studied by using a three dimensional semigeostrophic model.The calculating results show that the development of baroclinic waves on the mean zonal flows which are functions of height and latitude can cause cold and warm fronts. The disturbance development is the most intense in winter. and is the weakest in summer. The fronts caused by baroclinic waves is the strongest in winter and the weakest in summer correspondently.
