摘要
文中利用半地转锋生模式考虑了三种不同大气层结廓线和两种不同水平温度对比的天气尺度位温扰动场的作用。计算结果表明,层结对锋生速度影响较小,对锋区垂直运动影响却很大;天气尺度位温扰动对锋生速度和锋区垂直运动都有相当大的影响。
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.
