The evolution of frontal rainbands happening during the frontogenesis induced by deformation field is investigated through the numerical cloud model. Besides, in order to get insight from the results of numerical simulations, the semigeostrophic frontogenesis model is used to investigate the effect of diabatic heating on the frontogenesis and the analytical method of WKBJ is used to study the influence of large-scale deformation field and frontal circulation on the development of symmetric disturbance happened in the frontal zone.
为了加深对数值模拟结果的理解,还利用半地转模式对非绝热加热影响锋生的过程进行了讨论,通过WKBJ方法讨论了变形场锋生条件下对称扰动的发展,从中可以了解大尺度变形场和锋生环流对中尺度扰动的作用,这方面的工作可以对前面非静力数值模拟结果的理解提供帮助。

The frontogenesis process involves in the interactions among the systems of multiple scales. Since the hardness of the nonlinear problem, it is difficult to study frontogenesis analytically. The introduction of the effects of orography, friction and diabatic processes generally makes impossible the analytical resolution of the problem and leads to the use of numerical models. Primitive equations are numerical integrated together with a detailed description of physical processes. The circulation obtained is then used to diagnose and test theoretical mechanisms. It should be noted, however, that a fully description of frontogenesis in explicitly resolving the of large-, meso- and micro-scale flow in the same framework is not yet possible because of the excessive computer capacity and the time required. In order to deal with the problem, the action of large-scale background has been simplified and taken into consideration through the addition of the forcing into the nonhydrostatic cloud model.
大气锋生是一种多尺度相互作用的过程,理论研究遇到非线性的困难,在考虑地形、摩擦、非绝热等物理过程之后,解析研究更加棘手,通过数值模拟搞清其中的物理机制是重要的研究手段,但是把大、中、小尺度甚至微尺度的系统及其相互作用过程在一个模式里同时模拟好仍然受计算机速度和容量的限制,本论文在非静力云模式中通过强迫方式加入大尺度变形场的作用,在考虑到大尺度背景作用的同时,可以充分利用云模式所提供的丰富物理过程、非静力和高分辨率特点,开展一些过去较难进行的研究工作。

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.
关于锋面降水的产生和分布问题,近半个世纪以来,国内外气象学家进行了大量的观测和理论研究,但是由于问题的复杂性,至今仍有许多问题不清楚,我们利用非静力模式对变形场锋生条件下锋面雨带的发生、发展和演变过程进行了数值模拟和分析。
