项目摘要

This research involves support for participation of scientists from the University of Wyoming in the Convective INiation and Downburst Experiment (CINDE) to be conducted near Denver, Colorado in the summer of 1987. CINDE represents a collaborative effort between the National Center for Atmospheric Research (NCAR), the National Oceanic and Atmospheric Administration (NOAA) and university scientists and has the two goals of investigating the kinematics and thermodynamics of the initiation of storms by boundary layer convergence lines and the reasons for initiation of microburst downdrafts. In order to maximize available resources, the CINDE is being held in conjunction with two other field experiments: the Federal Aviation Administration's Terminal Doppler Weather Radar Experiment and the NOAA sponsored Denver AWIPS-90 Risk Reduction and Requirement Evaluation. The exact timing and location of the initiation of deep convection is of great value for a variety of purposes including improved prediction of rainfall amounts, public warnings of severe weather, timing of space craft launches and landings, etc. The hazard to aircraft posed by microbursts has been well established, but reasons for formation and maintenance of these intense downdrafts is not completely understood. Improved knowledge of this phenomenon, will contribute to better prediction and detection methods.

这项研究涉及对科学家参与的支持来自怀俄明州大学的对流层，下击暴流实验（CINDE）将于年在科罗拉多丹佛附近进行 1987年夏天。 CINDE代表了以下方面的合作努力：国家大气研究中心（NCAR），国家海洋和大气管理局（NOAA）和大学科学家们有两个目标，一是研究运动学，边界层引发风暴的热力学辐合线和微下击暴流产生的原因下降气流为了最大限度地利用现有资源，CINDE 与另外两项实地试验同时进行：联邦航空管理局的终端多普勒天气雷达实验和NOAA赞助的丹佛AWIPS-90风险降低和需求评估。深层火山爆发的确切时间和地点对流对各种目的都有很大的价值，包括改进了降雨量的预测，天气、航天器发射和着陆的时间等。微下击暴流对飞机造成的危害一直很好，建立，但形成和维持这些的原因强烈的下沉气流还没有完全被理解。改进知识这种现象，将有助于更好地预测，检测方法
