This project involves the investigation of meteorological factors controlling the outflow of aerosols from Southeastern Asia. The project has two components: 1) a historical analysis of meteorological data, visibility, and dust observations, and 2) operational support for the ACE-Asia intensive field campaign to be carried out during spring 2001. For the historical analysis, the structure, intensity, area of occurrence and interannual variability of meteorological systems, both cyclones and anticyclones will be documented using retrospective analyses of dynamical variables (i.e., meteorological fields obtained in a reanalysis) over a period of at least ten years. The research will include the surface and upper air fields, specifically including the larger-scale dynamical environment to which the surface systems relate and which control their development, motion and eventual decay. The spatial and temporal relationship of the occurrence of mineral dust to the parent meteorological system will be investigated.

该项目涉及控制东南亚气溶胶流出的气象因素的调查。 该项目有两个组成部分：1) 对气象数据、能见度和尘埃观测的历史分析，以及 2) 为 2001 年春季期间进行的 ACE-Asia 密集实地活动提供业务支持。对于历史分析，气象系统的结构、强度、发生区域和年际变化，气旋和反气旋将通过动力变量的回顾性分析（即， 至少十年内重新分析获得的气象场）。该研究将包括地表和高空领域，特别是与地表系统相关并控制其发展、运动和最终衰变的更大规模的动态环境。将调查矿尘发生与母体气象系统的时空关系。
