The feature of haze in Shaoxing City and its response to climate change(绍兴霾天气特征及其对气候变化的响应)
利用绍兴市1961~2013年5个气象站的霾观测资料和近年来自动气象站能见度、相对湿度资料,采用线性趋势、Morlet小波分析以及M-K突变检验等方法,分析了绍兴市霾天气的时空分布特征以及对气候变化的响应.结果表明:绍兴霾天气总体上呈西多东少分布,诸暨、柯桥和嵊州是霾天气高频区;霾天气呈冬多夏少的季节分布,11月至次年1月最多;近53年霾天气的频率总体不断增加,其中柯桥站气候变化倾向率为2. 23 d • a-1,特别是进入21世纪后显著增多,2003年是柯桥站的重大转折点;在霾天气日变化上,7:00起霾出现频率激增,16:00~17:00霾出现频率小幅上升,2个时段分别对应城市早晚高峰,表明...
