摘    要:目的]分析鲁西北灰霾天气特征及影响因素。方法]根据德州市11个县市1970~2009年灰霾和日照时数资料,对鲁西北灰霾天气的日、月、季、年变化及其原因进行分析,并讨论灰霾对日照时数的影响。结果]一日中09:00~14:00出现灰霾频率最多,不同季节日变化不一致;一年中12月出现灰霾日数最多(200 d),其次为1月(161 d),8月最少(20 d)。从季节上来看,秋、冬季灰霾出现多,分别占全年的23%、40%;春、夏季出现少,分别占18%、20%。年际变化上,1970~1979年鲁西北灰霾出现日数最少(110 d),趋势倾向率为2.27 d/a;2000~2009年最多(724 d),倾向率为16.35 d/a。灰霾日数的区域分布,德城区最多,其次为夏津,最少为禹城。灰霾日数的年际变化多与大气中的污染物浓度有关,月、季变化多受天气形势和气象条件控制。结论]该研究为灰霾的预防及其影响评估提供科学依据。
