| 摘 要： | 本文在二维半地转峰生模式中，考虑了水汽凝结加热和边界层抽吸作用对锋生及越锋环流的影响。水汽凝结加热考虑了大尺度凝结加热和对流凝结加热两种方式。计算结果表明：水汽凝结加热和边界层抽吸对峰区环流具有显著的作用，凝结加热使锋生加快，使锋区上升运动倍增，并使其水平尺度明显减少。边界层抽吸作用也使垂直环流加强。现在

| Abstract: | two-dimensional semigeostrophic frontogenesis model is used to study the influence of the condensation heating and frictional dissipation on frontogenesis circulation. Several numerical experiments are performed. The results have shown that the frontal circulations can be affected greatly by latent heating and friction. This study has shown that the large-scale condensation heating is more effective than convective condensation heating on frontogenesis. In particular the large-scale condensation heating has much more effects on vertical velocity than convective heating. It is also found that friction increases convergence in the surface boundary layer at front, but above there is condensating divergene whose effect is frontolytical. When the moist processes are included,the vertical velocity increases very much. |
