摘    要: 利用2004年4月20日至5月23日塔克拉玛干沙漠腹地塔中气象站浊度计和能见度仪逐日每5 min一次的加密观测资料及相应的地面气象常规沙尘观测记录,根据中国气象局沙尘暴观测分级标准分析了粒子散射系数在各级沙尘天气中的特征,表明浊度计观测的粒子散射系数在沙尘天气观测分级标准中有较明确的意义,沙尘天气时粒子散射系数与能见度为显著指数关系。

关 键 词:沙尘天气  观测  分级标准  浊度计  粒子散射系数(PSC)  能见度(VIS)

Abstract:Based on the every 5 minutes observation data of particle scattering coefficient(PSC) and visibility from April 20 to May 23 of 2004 on the Tazhong weather station,and according to the national observation classification criteria about sand-dust weather we analyzed the characters of particle scattering coefficient in different grades of sand-dust weather.Results showed that PSC had relatively specific significance in classification criterion of sand-dust weather observation;there was obviously exponential relation between visibility and particle scattering coefficient in sandstorm.
Keywords:sand-dust weather  observation  classification criteria  nephelometer  particle scattering coefficient(PSC)  visibility(VIS)
