南海夏季风背景下的广州气溶胶光学特性变化特征
VARIATION OF AEROSOL OPTICAL CHARACTERISTICS IN GUANGZHOU ON A BACKGROUD OF SOUTH CHINA SEA SUMMER MONSOON
摘要
Abstract
In order to study the variation of Guangzhou's aerosol optical characteristics on a large-scale background of South China Sea summer monsoon (SCSSM) and its possible cause,aerosol data derived at Panyu Atmospheric Composition Watch Station in Guangzhou and National Centers for Environmental Prediction/National Center for Atmospheric Research (USA) reanalysis data are used to take composite analysis and do physical diagnoses.Main results showed that aerosol extinction in Guangzhou increases first and then decreases during the active period of SCSSM.The data analyses indicate that stratification variation of the planetary boundary layer and environmental winds play important roles in affecting Guangzhou's aerosol optical characteristics.To a great extent,stratification of the planetary boundary layer is modified by regional diabatic heating and anomalous cyclonic circulation excited by monsoon convection would induce the environmental winds anomalies.关键词
