天气形势：
1日弱高压控制广大内陆地区，大范围降水过程结束。地表风力较弱湿度较大，为高排放地区雾霾重现提供了温床。

预报回顾：
当日矮马全国AQI预报在华北地区较实测略有低估，在享受了少有的几天清新空气后环渤海圈多个城市再次陷入轻度污染。近日新闻记者柴静及其团队制作播出的《穹顶之下》记录片也引爆了公众对雾霾污染及其背后牵涉的社会问题的广泛关注。其实空气污染并不可怕，可怕的是讳疾忌医似的冷漠与麻木。小小颗粒物折射的不仅仅是可见光，还有政府的公共服务意识以及每个人的日常生活方式。面对持续大面积沦陷的国土，饱受各类污染困扰的国人是时候想想应该怎样活。而标榜为人民服务的政府也该停止过去的“不抵抗”惰政，及时响应人民的呼声给民族留下个更加健康光明的未来。千头万绪不知从何抓起的话，也许可以从第一步信息透明公开开始。

I was wondering if you ever thought of changing the page layout
of your blog? Its very well written; I love what youve got to say.
But maybe you could a little more in the way of content
so people could connect with it better. Youve got an awful
lot of text for only having one or 2 images.
Maybe you could space it out better?
