摘要
本文是近期针对华北地区霾的长期变化特征持续强霾事件发生的环境和动力条件方面研究的个结。华北地区近50 年来霾日呈现明显的上升趋势，尤其是进入21 世纪以来，霾日增加明显同时，持续性霾事件的发生频次也呈现类似的上升趋势华北地区霾污染事件频发可以归因于不利的气象环境条件和人为排放的大量污染物的共同作用。气象环境条件方面主要表现为：在气变暖的大背景下，华北地区冬季气温的持续上升、地面风速的减小以及大气稳定度的加强均对霾日的增加有显著影响。厄尔尼诺(El Nino) 年冬季，东亚大槽偏弱，冷空气活动弱，华北地区盛行异常偏南风，有利于霾天气的形成；而拉尼娜(La Nina) 年冬季，东亚大槽偏强，冷空气活动强，华北地区盛行异常偏北风，不利于霾天气的形成华北地区持续强霾事件主要发生在平直西风型和高压脊型两类环流形势下，对流层中低层为持续深厚的下沉气流，使大气边界层厚度减少污染物扩散能力减弱，有利于霾天气的维持和加剧。
