摘要

2015年（2015年1月～12月），河北省气候年景总体偏好：气温偏高，降水接近常年，气象灾害普遍偏少，但局地灾情重。

2015年，河北省天气气候特点为：全省年平均气温12.6℃，较常年偏高0.8℃。冬季气温显著偏高，为2008年以来最暖冬季；春季气温偏高；夏、秋季接近常年。全省年平均降水量506.0毫米，接近常年，较2014年偏多近3成，降水时空分布不均。夏季降水偏少，部分地区突破历史极小值，致使我省出现大范围气象干旱；春、秋季降水显著偏多，超过30%的区域秋季降水异常偏多；冬季接近常年。全省年平均日照时数2319.1小时，属偏少年份。秋季日照显著偏少；冬、春、夏季接近常年。

2015年，河北省气象灾害特点为：雾霾天气多于常年，重雾霾偏少。冬、秋季雾霾偏多，春、夏季偏少。阶段性气象干旱严重，夏旱影响较大。高温日数偏少，7月13日出现极端高温事件，21个县（市）达到或突破40℃。暴雨日数显著偏少，局地出现强降水，部分地区出现洪涝灾害。降雪日数接近常年，为近5年最多，11月降雪异常偏多。寒潮、风雹、沙尘过程偏少。连阴雨天气多于常年，秋季异常偏多，秋末阴雨寡照历史罕见。总体而言，2015年河北省气象灾害发生的频率和损失程度低于近10年平均水平，损失程度属于“中等偏轻”年份。
