Meteorological Controls on Aerosol Distributions in ACE-Asia

该项目涉及控制东南亚气溶胶外流的气象因素的调查。该项目有两个组成部分：1)气象数据、能见度和尘埃观测的历史分析；2)2001年春季将开展的ACE-亚洲密集实地活动的业务支助。对于历史分析，气旋和反气旋气象系统的结构、强度、发生面积和年际变化将通过对至少十年期间的动力变量(即再分析获得的气象场)的回顾分析来记录下来。这项研究将包括地面和高空气场，特别是与地面系统相关的、控制它们的发展、运动和最终衰变的更大尺度的动力环境。将调查矿物粉尘发生与母气象系统的时空关系。

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.
