Rainstorm Warning Information in Beijing: Exploring the Local Perceptions and Views

Abstract

Based on the public's cognition, evaluation and expectation of rainstorm warning information in Beijing, the descriptive statistics and non-parametric test methods were used for data analysis. The results show that more than 80% of the public can recognize the importance of rainstorm warning, but only half of the public pay attention to the rainstorm warning information. As for the method of issuing early warning, the village broadcasting and electronic display, and network communication channels need to be strengthened. Although the rainstorm warning information was released in time, the update process was not effectively communicated, and the information update period was long, it could not meet the public's demand for real-time attention to heavy rain. As far as the content of the warning information is concerned, false alarm effects of the rainstorm warning exist. According to the results, it is concluded that lead time can be extended by adding the update of warning information, and the probability of rainfall could be introduced to rainstorm warning information. These guide the design of rainstorm warning and promote understanding how the public responds to the warning.
