摘要：

Geostrophic adjustment and frontogenesis are examined by means of the 2-D ARPS model.The simulation shows that.without the large-scale forcing,both the frontogenesis and frontolysisare observed during the geostrophic adjustment process and the intensity of the front oscillates inthe case of no discontinuity.The convergence (divergence) induced by the secondary circulation isthe most important factor for frontogenesis (frontolysis) at the top and bottom boundaries.Theamplitude and period of oscillation are dependent on the initial atmospheric stratification and theCoriolis frequency,and they are related to the inertio-gravity wave.
