The effects of friction in surface layer on the structure of front and the frontogenesis in boundary layer, the interaction of orographic disturbance with front, the influence of diabatic process and moist process on the frontogenesis are investigated. Second, the occurrence and development of frontal rainbands have been studied extensively through the observational and theoretical approaches near half-century. However, there are still some problems needing further investigations because of the complication of the precipitation process.
