Project description

The sci-fi movie “The Wandering Earth” became a big hit in China’s cinemas during 2019 Chinese New Year; in real life, however, residents in southern China felt that the sun had gone wandering since the beginning of 2019 – an abnormally long rainy season.

The first infographic shows the general weather pattern of Feburary. Different weathers of nine cities in Yangtze River Delta area are visualized in different colors. Data covers the entire Feburary. To make the graphs more colorful, detailed and accurate, the circle of each city each day is divided into four pieces, colored according to the observed weather of a certain timepoint. The dominately bluish infograhic with scattered yellow sectors confirms people\’s experience of a dominately rainy Feburary with very occasional sunshine.

Although people complained most about rainy days were the ones living in Yangtze River Delta, data shows that most of southern China (especially cities along Yangtze River) had a very wet winter this year. The two maps of China demostrates the volumns of rain and sun in different cities in a straightfoward way. Larger and less transparent dots indicate larger volumns while smaller and more transparent dots indicate smaller volumns.

Last part is two listcles of southern Chinese cities that broke their own records in the past six decades and cities that didn\’t in terms of rain and sunshine. The inner polar bar chart represents the number of rainy days in a winter for each of past sixty years, and the outer polar bar chart represents the hours of sunshine in a winter. The light yellow shading of the outer part reminds people of the image of sun\’s halo.

What makes this project innovative?

1) A defining visualization piece to mark the historically-remarkable rainy winter. 2) The project not only echoes the complaints about the Yangtze Delta area, but also demonstrates most of southern China had a very wet winter this year. Even cities that didn't break any record is worth mentioning. For example, Chongqin, had only 66.9 hours of sunshine during the entire winter, which means only 45 minutes of sunshine on average for each day. 3) The visualization is a combination of sophiscated polar bar chart and simple but to-the-point maps. The maps demonstrates straightforwardly the sun was missing and the rain was lingering during this winter. The polar bar chart use the form of image of sun's halo, which enhances the difference of sunshine hours between cities. 4) The project applied social media strategy successfully. The Paper set up a hashtag on Weibo named #太阳流浪最久的一次# (the longest the sun ever wandered), and it became the 19th most trendy topic on the entire social media platform.
