Modification Continental Air Masses Moving

项目摘要

Many ingredients are required for the formation of severe weather in the central and eastern parts of the United States. One of these factors, which is most difficult to forecast, is the timing and location of the return of warm, moist, unstable air from the Gulf of Mexico. This research is part of a larger National Oceanic and Atmospheric Administration (NOAA) led project which seeks to improve understanding of the modification of cold air outbreaks as they move over the warm Gulf waters. Of particular interest are the nature of this airmass modification and the factors which control it. A combined modelling and observational approach is planned including a small field program. Observational systems will include the NOAA P-3 research aircraft, supplemental soundings from National Weather Service (NWS) upper air stations and satellite data. Four Cross-chain Loran Atmospheric Sounding Systems (CLASS) from the National Science Foundation sponsored National Center for Atmospheric Research will be used to improve the spatial density of the sounding information available from the NWS sites. Three of these systems will be placed in the Gulf of Mexico -- two aboard research vessels and one on an oil drilling platform. The data collected from this ensemble of instrumentation will be the most complete to date on airmass modification over the Gulf.

在美国中部和东部形成恶劣天气需要许多成分。这些因素之一是最难预测的，是墨西哥湾温暖，潮湿，不稳定的空气回归的时机和位置。这项研究是更大的国家海洋和大气管理局（NOAA）LED项目的一部分，该项目旨在提高人们对冷空气爆发的改变，因为它们在温暖的海湾水上移动。特别令人感兴趣的是这种空气质量修改的性质及其控制的因素。计划了一种组合的建模和观察方法，包括小型野外计划。观察系统将包括NOAA P-3研究飞机，国家气象局（NWS）上空站的补充声音和卫星数据。国家科学基金会赞助的国家大气研究中心将使用四个跨链Loran大气发声系统（类）来改善NWS网站可从NWS网站获得的声音信息的空间密度。这些系统中的三个将放置在墨西哥湾 - 两艘在研究船上，一个在油钻台上。从这种仪器合奏中收集的数据将是迄今为止在海湾的空气质量修改上的最完整的数据。
