| 摘 要： | 利用2009年6月—2010年5月苏州市气象局霾监测点颗粒物浓度、能见度、相对湿度、风速、风向、气温等观测资料，分析了苏州能见度变化特征，建立了能见度和影响因子的统计模型，研究了能见度和气象因子及颗粒物浓度的关系。结果表明：苏州市能见度有明显的季节变化,春季能见度最好，秋季能见度最低；能见度日变化显著，最低能见度通常出现在清晨，午后明显好转；PM10、PM2.5、黑碳浓度值和相对湿度与能见度都呈反相关关系，但黑碳对能见度的影响不如PM10和PM2.5对能见度的影响明显；风速与能见度呈正相关关系，在东南、南东南风向时能见度值最高。

| Abstract: | Based on the every hour observation data from June 2009 to May 2010 in Suzhou,the relationship between visibility and the impact factors are analyzed.The statistical models of visibility and impact in Suzhou has been established.The conclusions are as follows:Suzhou visibility has obvious seasonal variation.Visibility is best in spring,while the lowest visibility in autumn.The diurnal variation of visibility is also significant,and the minimum visibility is usually in the morning.PM10,PM2.5,black carbon con... |
