March 24, according to the China Meteorological Administration Web site news, 24th 16:30 Beijing Meteorological Bureau launched heavy air pollution level-IV emergency response, expected on 28th, cool air rushed to disperse the haze.
Due to the recent weather conditions are very bad for the spread of pollutants in the air, has a tendency to gradually accumulate and aggravating air pollutants, from 24th to 27th, Beijing will have a persistent haze. 28th is expected, cool air rushed to disperse the haze.
Beijing Municipal meteorological observatory predicted the haze will last until the 27th, during which air pollutants has a tendency to gradually accumulate and aggravating. Beijing Meteorological Observatory chief forecaster said Yu Bo, which was weaker in view of the recent control of Beijing's pressure, relatively static stability of the atmosphere, the meteorological conditions are not conducive to the spread of pollutants in the air, will continue for the next three days the weather situation, difficult for the air pollutants diffusion or sedimentation.
24th under the influence of cold air at night, spread in Northern conditions had improved, but southern areas will remain mild to moderate haze, visibility was about 2 to 4 km.
28th is expected during the day, a moderate cold air will bring about 4 jiuchang North wind to reach the capital city to disperse the haze, the sky clear, visibility is good, sunny weather again. 30th, there will be a new cold front ensued, level 3, 4 North wind will once again sweep the capital. In short, fine later this week, also is appropriate.

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。
