TOGA: McIDAS Operational Applications for TOGA COARE

这项研究将为使用McIDAS(人机交互数据访问系统)工作站的TOGA/COARE提供关键的业务支持和相关的科学应用。TOGA/COARE密集观测期(IOP)将于92年11月至93年2月在热带太平洋西部数据稀少的区域进行。在IOP期间，TOGA/COARE必须依靠卫星图像和全球环流模式(GCM)的分析和预报来作出日常业务决策。McIDAS是用GCM和区域模式分析的热力和动力场合成卫星图像的最先进工具。作为该项目的一部分，将在IOP期间通过两个专门的McIDAS工作站提供科学和后勤支持。大部分数据将从澳大利亚气象局McIDAS获得，另外一些数据将通过互联网从威斯康星州的McIDAS获得。McIDAS工作站将放置在两个关键地点：澳大利亚昆士兰州汤斯维尔的COARE运营中心和所罗门群岛的霍尼亚拉，关键的运营决策将在那里做出。除了提供眼压期间所有可用的数据、分析和预测外，该项目还包括一系列眼压前和过去的眼压研究。眼压前研究将把GCM分析和预测与COARE前一年的卫星图像进行比较，以评估模型和评估预测技能。过去的眼压研究将集中于总结眼压的天气和云事件，并完成在眼压前开始的GCM评估。眼压期间所做的分析和模型预测的比较。

This research will provide critical operational support and related scientific applications for TOGA/COARE using McIDAS (Man- computer Interactive Data Access System) workstations. The TOGA/COARE Intensive Observing Period (IOP) will take place in a data sparse region of the far Western Tropical Pacific from November 92 through February 93. TOGA/COARE must rely on satellite imagery and global circulation model (GCM) analyses and forecasts for making daily operational decisions during the IOP. McIDAS is the most advanced tool for synthesizing satellite imagery with thermodynamic and dynamic fields anlayzed by GCM and and regional models. As part of this project, scientific and logistic support will be provided during the IOP with two dedicated McIDAS workstations. Most data will be obtained from the Bureau of Meteorology McIDAS in Australia with some additions from the Wisconsin McIDAS through Internet. McIDAS workstations will be placed at two key locations: the COARE Operations Center in Townsville, Queensland, Australia and in Honiara, Guadacanal, Solomon Islands, where critical operational decisions will be made. Besides providing all available data, analyses, and forecasts during the IOP, this project includes a series of pre-IOP and past IOP studies. The pre-IOP study will compare GCM analyses and forecasts to satellite imagery from the year before COARE to evaluate the models and assess forecasting skill. The past IOP study will focus on summarizing the weather and cloud events of the IOP and completing the GCM evaluations begun in the pre-IOP. The comparisons of analyses and model forecasts made during the IOP.
