Effects of Atmospheric Stratification and Synoptic-scale Potential Temperature Disturbances on the Frontogenesis
大气层结和天气尺度位温扰动对锋生的作用

Three kinds of stratification profiles and two different amplitudes of synoptic-scale potential temperature disturbances are investigated by using a semi-geostrophic frontogenesis model. The results of model simulation show that the stratification has a little effect on the speed of frontogenesis, but it plays a very important role in the vertical motion field in the frontogenetical area. The effects of the synoptic-scale potential temperature disturbances on the speed of frontogenes is and the vertical motion field near front area are quite important.
