This proposal on "A Study of Atmospheric Fronts Over Mountainous Terrain" between Dr. William Blumen of the University of Colorado and Professors ZHAO Ming and WU Rongsheng of Nanjing University is jointly sponsored by NSF and the Chinese State Educational Commission (SEDC). The investigators propose to study physical processes that affect atmospheric frontal motions over the earth's orography, specifically the mountainous regions of China. They will emphasize the role of the planetary boundary layer in this process. The investigations will consist of 1) observational and analysis study to document and examine various cases of frontal distortion by orography; 2) a numerical modelling effort to simulate frontal motion over terrain features such as the Tien Shan complex in western China; and 3) a theoretical study to examine the relation between frontal motion and planetary boundary processes. The investigators will carry out the first two phases at Nanjing University, where the data, analysis procedures and numerical model resources are. The Chinese investigators will plan and execute these aspects of the research in consultation with the American investigator. The theoretical phases, including analysis of the numerical experiments, will be carried out jointly through visits. Scientists do not completely understand the physical processes that affect frontal passage over mountainous terrain, complicating numerical weather prediction. The grid resolution and model physics may be insufficient to depict fronts adequately and, therefore, meteorological predictions in the vicinity of large mountain complexes are generally less reliable than elsewhere. The proposed research is of mutual interest to both the Chinese and American investigators. The particular emphasis placed on orographic effects in China will expose Western scientists to meteorological observations that have not been readily accessible, and the sharing of resources contributes to the research program.

这份关于“大气锋面的研究”的建议， 山区地形”之间的威廉·布鲁门博士的 科罗拉多大学与赵明、吴教授 南京大学荣盛与NSF联合发起 中国国家教委（SEDC）。 研究人员建议研究物理过程， 影响地球地形上的大气锋面运动， 特别是中国的山区。 他们将 强调行星边界层在这方面的作用 过程 调查将包括1）观察 和分析研究，以记录和检查各种情况下， 由地形引起的锋面畸变; 2）数值模拟 努力模拟地形特征上的正面运动，例如 中国西部的天山杂岩; 3） 理论研究来检验额叶与额叶之间的关系 运动和行星边界过程。 调查人员 将在南京大学开展前两个阶段的工作， 其中数据、分析程序和数值模型 资源是。 中国调查人员将计划和 执行这些方面的研究咨询， 美国调查员。 理论阶段，包括 分析的数值实验，将进行 通过访问。 科学家们并不完全理解 影响山区锋面通过的过程 地形，使数值天气预报复杂化。 的 网格分辨率和模型物理可能不足以 充分描绘锋面，因此， 在大型山地综合体附近的预测是 一般比其他地方更不可靠。 拟议 研究对中国和 美国调查员。 特别强调 中国的地形效应会让西方科学家 到气象观测， 资源共享有助于 研究计划。
