CALPUFF-AERMOD大气预测模式耦合系统

Coupled System of CALPUFF-AERMOD

AERMOD和CALPUFF在模型应用尺度、适用范围、气象与地形预处理以及特殊计算功能模块等方面具有自身的特点和优势。为了使模型系统计算结果合理科学,本文综合考虑AERMOD和CALPUFF的应用范围和特点,建立了CALPUFF-AERMOD耦合系统。以广东省东莞、中山、深圳的污染源和气象条件等资料为背景,进行污染预测模拟,以此评价模式的模拟性能,并对比CALPUFF与AERMOD的预测结果,最终计算得出的预测结果相对科学合理。

AERMOD and CALPUFF models both have their own characteristics and advantages in application scale,meteorological and geophysical data preprocessing and special calculation.The application scale and characteristics of AERMOD and CALPUFF are considered comprehensively.The coupled system of CALPUFF and AERMOD is built and developed.The pollution sources and meteorological conditions in Dongguan,Zhongshan and Shenzhen in Guangdong Province are taken as the background information.The pollution predictions of three cities are simulated to evaluate the simulation functions.The prediction results are evaluated and compared to reach the conclusion that the results are reasonable and scientific.
