The Convective and Orographically-induced Precipitation Study (COPS) is an international field experiment scheduled to take place over moderate-mountain terrain in southwestern Germany and eastern France during June-August 2007, This proposal provides the scientific justification and experimental integration design for the deployment of two Doppler on Wheels (DOWs) mobile radars in the Black Forest region during COPS. The overarching COPS goal is to improve the skill of quantitative forecasts oforographically- induced convective precipitation. The terrain relief in the COPS region is -1000 m and it suffers from low forecast skill of quantitative precipitation and flash flooding potential. The DOW component of COPS aims to combine the DOW data with the multitude of European research and operational instruments to improve the basic understanding of the initiation and evolution of convection over moderate-mountain terrain. This improved understanding is expected to impact very short period forecasts of convective and precipitation processes. COPS research objectives directly complement research strategies developed in workshops sponsored by the U.S. Weather Research Program to improve Quantitative Precipitation Forecasts (QPFs; Fritsch and Carbone 2004; Dabberdt et al. 2005). COPS complements two recent field programs: the International H2O Project (IHOP_2002) and the Convective Storm Initiation Project (CSIP) in 2005. These three convection initiation and QPF field programs together cover broad flow regimes, varying topography, and extreme land-use variations. With different countries taking the lead on providing facilities, the programs are more cost effective than if the U.S. or E.U. attempted several programs aimed at different flow regimes over their regions. The mobility of the DOW radars will be a tremendous asset to COPS. This mobility enables them to be deployed in a variety of locations as meteorological conditions dictate. The DOWs will be strategically deployed in locations such that they can obtain dual- Doppler wind retrievals in regions not well observed by the German C-band operational and POLDIRAD research radars, such as in the lowest kilometer within the far reaches of the dual-Doppler lobes of those radars or within regions beyond the dual-Doppler lobes of these radars. Retrieval of the low-level kinematic fields is essential for understanding the boundary layer processes critical to convection initiation. COPS will be the first major international field campaign focused on the improvement of summertime convective QPF in a moderate-mountain region. It will constitute a major contribution to one of the most difficult and societally relevant research problems facing the atmospheric sciences community. Successful completion of the proposed research will improve the basic understanding of the initiation and evolution of convection over moderate-mountain terrain.

对流和对流诱发降水研究(COPS)是一项计划于2007年6-8月在德国西南部和法国东部中等山区进行的国际野外试验，该提议为在COPS期间在黑森林地区部署两个车轮上多普勒(DOW)移动雷达提供了科学依据和实验一体化设计。COPS的首要目标是提高对地形诱发对流降水的定量预报技能。COPS区地形起伏为-1000m，定量降水预报技巧较差，洪水潜势较小。COPS的DOW部分旨在将DOW数据与欧洲的大量研究和业务工具结合起来，以提高对中等山区对流开始和演变的基本理解。这一认识的改进预计将对对流和降水过程的极短期预报产生影响。COPS研究目标直接补充了在美国天气研究计划赞助的研讨会上制定的研究战略，以改进定量降水预报(QPFS；Fritsch和Carbone 2004；Dabberdt等人)。2005)。COPS是对最近的两个实地项目的补充：国际H2O项目(IHOP_2002)和2005年的对流风暴启动项目(CSIP)。这三个对流启动和QPF现场计划一起涵盖了广泛的流动状态、不同的地形和极端的土地利用变化。由于不同的国家带头提供设施，这些项目比美国或欧盟针对各自地区的不同流动状况尝试几个项目的成本效益更高。陶氏雷达的机动性将是警察的一笔巨大财富。这种机动性使它们能够根据气象条件部署在不同的地点。DOW将被战略性地部署在这样的地点，以便它们能够在德国C波段作战雷达和POLDIRAD研究雷达没有很好观测到的区域获得双多普勒风反演，例如在这些雷达双多普勒瓣远距离内的最低公里处，或者在这些雷达双多普勒瓣以外的区域内。低层运动场的反演对于理解对流形成的关键边界层过程是至关重要的。COPS将是第一个主要的国际实地活动，重点是改善中等山区夏季对流QPF。它将对大气层科学界面临的最困难和最具社会意义的研究问题之一作出重大贡献。这项拟议研究的成功完成将提高对中等山区对流形成和演化的基本认识。
