气象宣传网站运营发展思考——以中国天气网广西站改版为例

融媒体时代,公众获取气象信息的渠道增加,部分传统的天气服务类网站由于不能满足公众的需求,浏览量逐渐下降。为了顺应时代的发展趋势,广西气象服务中心开始对气象宣传网站的运营发展进行调研和思考,并对所运营的“中国天气网广西站”网站进行了改版。改版从基于用户位置的天气信息推送、提供便捷的气象灾害预警信号查询、做好天气新闻栏目、搭建专题模块、创新旅游天气模块、搭建公众关注度最高的天气信息模块、设立“东盟天气”子页面、增加“广西天气”气象服务新媒体品牌联动、对整体页面设计进行优化等方面进行。

Surface Trace Gases at a Rural Site between the Megacities of Beijing and Tianjin

The North China Plain(NCP) has recently faced serious air quality problems as a result of enhanced gas pollutant emissions due to the process of urbanization and rapid economic growth.To explore regional air pollution in the NCP,measurements of surface ozone(O3),nitrogen oxides(NOx),and sulfur dioxide(SO2) were carried out from May to November 2013 at a rural site(Xianghe) between the twin megacities of Beijing and Tianjin.The highest hourly ozone average was close to 240 ppbv in May,followed by around 160 ppbv in June and July.High ozone episodes were more notable than in 2005 and were mainly associated with air parcels from the city cluster in the hinterland of the polluted NCP to the southwest of the site.For NOx,an important ozone precursor,the concentrations ranged from several ppbv to nearly 180 ppbv in the summer and over 400 ppbv in the fall.The occurrence of high NOx concentrations under calm conditions indicated that local emissions were dominant in Xianghe.The double-peak diurnal pattern found in NOxconcentrations and NO/NOx ratios was probably shaped by local emissions,photochemical removal,and dilution resulting from diurnal variations of surface wind speed and the boundary layer height.A pronounced SO2 daytime peak was noted and attributed to downward mixing from an SO2-rich layer above,while the SO2-polluted air mass transported from possible emission sources,which differed between the non-heating(September and October) and heating(November) periods,was thought to be responsible for night-time high concentrations.

My-Cast.com借东风展业务

不少网上资讯网站,内容多离不开衣食住行、吃喝玩乐、又或是财经、娱乐、新闻等资讯,以丰富内容吸引读者;然而,即将在美国推出的My-Cast.com,将在网上独沽一味报道天气,却仍能以私人途径集资810万美元发展。原来据调查显示,浏览天气消息是在美国网民上网的原因之中排行第4位,较上网看股票、新闻或体育赛果排名更高,可见天气报告网站的发展潜力是不容小觑的。
