In the recent years,with rapid development of mobile internet,new media platform has been developing at full speed,such as twitter,WeC hat and APP. It has wide information dissemination channels,fast release frequency and efficient interactive mode. According to the characteristics of new media,we set forth the current situation of public weather service. Through the questionnaire survey,we have analyzed the actual demand of public from three aspects,including the public reading habits,characteristics of sharing and transmission and defect of information distribution. Finally,we have discussed the future trend of meteorological new media,which will promote public service effectiveness of meteorological new media by considering requirement,applying new technology and reasonably using platform. 展开更多

Taking Meteorological Knowledge official micro-blog " Meteorological Knowledge" and Beijing Meteorological Bureau official micro-blog " Meteorology Beijing" as the research objects,the differences of different types of meteorological government micro-blog and the contribution of each factor were analyzed by comparing changes of the number of fans,micro-blog comments and forwarding and other key elements during March1 to May 31 in 2012. The results showed that the number of fans was one of important indexes to determine the influence of meteorological government micro-blog,and the high active fans played a more prominent role. During the period of study,the fans number of " Meteorology Beijing" was far more than " Meteorological Knowledge",the daily micro-blog released number and comment forwarding number were both more than " Meteorological knowledge",but the proportion of active fans of " Meteorological knowledge" was larger than " Meteorology Beijing". Timeliness was of greater contribution to advancing the meteorological government micro-blog influence. During the period of study,the proportions of comments and forwarding number of morning weather forecast were the largest,the evening weather forecast took the second place,and the noon was the smallest.But the influence of noon weather forecast micro-blog increased most highly approximately by 15% because of the higher timeliness. The content and form also made great contribution to the influence of meteorological government micro-blog. Comparison of different types of meteorological micro-blog showed that,the number of fans and the influence of meteorological government micro-blog which mainly published real-time meteorological information were larger than which mainly published meteorological popular science knowledge. 展开更多
