Parameterization of Vegetation for Meterological Models

这项为期三年的美国-南斯拉夫气候变化和中尺度气象学合作研究项目是由诺维萨德大学大田和蔬菜作物研究所的德拉古丁·米哈洛维奇和科罗拉多州立大学的罗杰·a·皮尔克共同完成的，目的是调查地表与大气的相互作用。这些研究将有助于改进天气和气候预测模型，并加强对气候对生态系统和环境影响的认识。南斯拉夫的合作为Pielke博士的NSF研究资助增加了一个国际层面，该研究资助的主题是地表热量和水分通量对中尺度气候和天气的影响。在他的NSF资助下，Pielke博士开发了RAM模型（区域大气模型）。这种合作的目标是通过制定更精细的陆地表面参数规格来改进RAM。南斯拉夫的参与包括将土壤和植被参数化纳入科罗拉多州RAMS模型，并利用南斯拉夫农业带的实地数据检验其准确性。该项目得到了美国-南斯拉夫科学技术合作联合委员会的批准，并通过一个由美国和南斯拉夫政府对等捐款组成的联合基金得到支持。美国的捐款每年由国务院提供。没有涉及NSF基金。除了为美国科学家旅行提供的资金外，该奖项全部授予了这家南斯拉夫机构。美国国家科学基金会推进科学知识的目标将通过南斯拉夫和美国科学家的联合科学努力和互补的专业知识得到促进。

The objective of this three-year U.S.-Yugoslav cooperative research project in climate change and mesoscale meteorology between Dragutin Mihailovic of the University of Novi Sad's Institute of Field and Vegetable Crops and Roger A. Pielke of Colorado State University is to investigate land surface - atmosphere interactions. These studies will contribute to improved weather and climate prediction models and enhance understanding of climate impact on ecosystems and the environment. Yugoslav collaboration adds an international dimension to Dr. Pielke's NSF research grant on the Influence of Surface Heat and Moisture Fluxes on Mesoscale Climate and Weather. In his NSF grant, Dr. Pielke developed the RAM model (Regional Atmospheric Modeling). The objective of this cooperation is improvement of the RAM through the development of finer specifications of land surface parameters. Yugoslav involvement consists of integrating soil and vegetation parameterizations into the Colorado State RAMS model and testing its accuracy by using field data derived from the agricultural belt of Yugoslavia. This project was approved by the U.S.-Yugoslav Joint Board on Cooperation in Science and Technology and is supported through a joint fund consisting of matching contributions from the U.S. and Yugoslav governments. The U.S. contribution is provided annually by the Department of State. No NSF funds are involved. The award, except for funds for U.S. scientist travel, is made to the Yugoslav institution. NSF's objective of advancing scientific knowledge will be promoted through this joint scientific effort and complementary expertise of the Yugoslav and U.S. scientists.
