北京气象局启动空气重污染四级应急响应|空气|应急响应|气象局_新闻资讯

　　中新网3月24日电 据中国气象局网站消息，24日16时30分北京市气象局启动空气重污染四级应急响应，预计28日，冷空气将赶到驱散霾。

　　由于近日气象条件十分不利于空气中污染物的扩散，空气污染物有逐渐聚积和加重的趋势，24日至27日，北京将有持续性霾天气。预计28日，冷空气将赶到驱散霾。

　　北京市气象台预计，此次霾天气将持续至27日，期间空气污染物有逐渐聚积和加重的趋势。北京市气象台首席预报员于波说，这是由于近日控制北京的气压场较弱，大气相对静稳，气象条件十分不利于空气中污染物的扩散，未来三天这种天气形势还将持续，空气中的污染物难以扩散或沉降。

　　另外24日夜间受到冷空气的影响，北部地区的扩散条件有所好转，但是南部地区仍将维持轻度到中度霾天气，能见度约为2至4公里。

　　预计28日白天，一股中等强度的冷空气将携4级左右北风到达京城来救场，驱散霾，天空放晴，能见度转好，晴朗天气重现。30日还会有新一股冷空气接踵而至，3、4级北风又将再次清扫京城。总之，本周后期天气不错，还是比较适宜出行的。

　　另外，由于本周前期冷空气活动弱，北京气温上升明显，白天最高气温在22℃-25℃之间，其中，周三最高气温将达到25℃左右，体感十分温暖。周四到周五白天天气转阴，气温有所回落，但依然比常年显著偏高。
