北京大学大气环境模式PUMA的改进及其在沈阳地区的应用研究
Improvements to the Peking University Model of Atmospheric Environment (PUMA) and Its Application over Shenyang,China
摘要
Abstract
Two improvements were introduced to the Peking University model of atmospheric environment(PUMA) to expand its utility.First,a new generation of mesoscale meteorological model WRF was adopted to provide meteorological fields for PUMA;second,Grisogono scheme,a non-local vertical turbulent mixing parameterization,was introduced into PUMA.Both WRF and PUMA were evaluated with observed data over Shenyang China in winter.Under convective boundary layer at noon,PUMA was improved by Grisogono scheme.The diurnal cycle of SO2,with low values during daytime and high values during nighttime,was negatively related to the cycle of boundary layer height according to the simulation.The improved PUMA can be applied to atmospheric environment forecasting and warning.关键词
