中文摘要: 本文通过对天津气象站历史能见度资料和边界层观测站能见度、相对湿度、气溶胶观测资料进行分析,获取天津低能见度基本特征,在此基础上,基于WRF Chem大气化学模式模拟了2010年10月和2011年1月天津地区大气水平能见度。结果表明:天津地区低能见度事件主要发生在每年11月至次年1月,在获取PM2.5和PM10质量浓度、相对湿度的基础上可较好地推算大气水平能见度,利用 WRF Chem大气化学模式和拟合公式,可以有效的进行能见度等级模拟和预报。
Abstract:Based on historic visibility data of 12 stations and observed data of visibility, relative humidity, and aerosol during 2009-2011 in Tianjin, the basic characteristics of low visibility is analyzed. In addition, the atmospheric chemical model of WRF Chem is used to simulate the atmospheric horizontal visibility from October 2010 to January 2011 in Tianjin. The results show that low visibility mainly happens in every November to the next January. The atmospheric horizontal visibility can be better calculated on the basis of acquisition of PM2.5, PM10 and the relative humidity. And the use of WRF Chem atmospheric chemical model and fitting formula, the visibility can be effectively simulated and forecasted.
