| Summary: | 碩士 === 國立政治大學 === 傳播學院碩士在職專班 === 106 === Since the world has experienced extreme weather and natural disasters constantly, weather information has been closely related to the lives of human being. According to the survey conducted by the Central Meteorological Bureau in 2015, TV is still the main channel for the public to access to meteorological information and meteorological communication is a part of science communication. Based on a typhoon from the birth to death, this study explores 4 weather presenters during prime time broadcasting by the use of content analysis which includes 3 aspects: message presentation, media design and performace. Also, by conducting in-depth interviews with the 4 presenters, this study examines how the domestic weather presenters communicates with the public before and during the authorities announces the typhoon alert, and after the alert is lifted.
News media face fierce competition in recent years which leads to the rise of infotainment. For example, TV weather presenter starts to dramatize the strength of typhoon when it's just 1000km or 2000km away. This study found that presenter’s academic background in science does affect the structure of narration. When typhoon is still far away and the impact is variable, Ren Li-yu and Lin Jia-kai are more likely to present with a conservative tone while Dai Li-kang is more suggestive. Wang Shu-li has the strongest suggestive tone. During the alert, Ren Li-yu focuses on the typhoon analysis, Lin Jia-kai is fond of using charts and graphics to analyze the current wind speed and rainfall. Dai Li-gang puts more emphasis on reminding audience to be cautious and to do as much as one can to prevent the typhoon. Wang Shu-li’s style is relatively lively and she tends to make an analogy with surrounding things to describe the typhoon. After the typhoon alert is lifted, Ren Li-yu, Lin Jia-kai and Dai Li-gang resumes to the usual weather broadcasting style immediately. However, Wang Shu-li’s way of presenting stays the same. From the aspect of media design, Lin Jia-kai presents in a virtual studio with particular TV screen layout, charts and graphics which is clearer and better than the other three. When it comes to performace style, the 4 presenters have their own style, Ren Li-yu is sincere and serious. On the other hand, Lin Jia-kai is more approachable and affinitive. Dai Li-gang seemed to be more aggressive and provocative. Lastly, Wang Shu-li tends to present the program with a lively style. Gestures and stylus could be important tools while presenting. Gesture weighs during broadcasting while the stylus could be used to show their professionalism, attracting more viewers.
From the results of the analysis, the study also proposed typhoon forecasting criteria, first of all, the weather presenter’s long-term professional image. The narrative structure of the message must be adjusted as the typhoon approaches. When the typhoon is far away, the narration should be focused on “educating” the audience the knowledge of the atmospheric environment. While the typhoon is gradually close, the capacity to analyze the typhoon is the key to prevail against others. When the typhoon alert is announced, the ability to explain how the typhoon would impact Taiwan is the concern of audience. The key principle for weather forecast's animated background is visualization. The graphics and texts should be simple and easily digestible. Also, the program should let viewers absorb and familiarize with these presented charts. One thing that needs be avoided is visual fatigue. In terms of performace, some presenters are calm and serious, some are cordial and lively. Since television relies heavily on visualization, moving pictures are more eye-catching than still images. Otherwise, both eye contact and facial expressions, gestures, the use of touch pen, or even the body movement all play a dispensable role. Combining weather presenter’s narrative, gesture and chart, can deliver the best weather forecasting performance.
TV weather presenter’s personality and personal style establishment is helpful to build brand image and earn the trust of the audience. Professional weather presenter with practical and academic training, plus good performance training; or for journalist without meteorological background, through abundant professional news training and self-study, they can win audience’s heart and trust.
