摘要
为了研究台风系统对我国城市大气环境质量的影响,以2005年2次台风过程为例,对该期间PM10的区域性环境资料和相关气象资料进行分析,发现北京、绍兴等城市都出现明显的PM10重污染.利用区域环境和气象系统资料作出了诊断分析和数值模拟,结果表明,台风系统外层区大气环境背景场非常有利于污染物的累积,是该区域内城市形成重污染现象的主要原因.
To study influence of typhoon in the regional air environmental quality in China,this paper analyzed the important pollutant PM_(10) and the relevant meteorological data during two typhoon processes in 2005. Results show that there were obvious pollutant processes in the cities in China.Based on the data of regional environmental data and meteorological data,we diagnosed and modeled two typical processes.Research illuminated that the typhoon system is the important reason for the heavy pollution in some cit...
