暴雨特征信息的时空尺度及重现期的探讨

Study on the temporal and spatial scales and recurrence period of characteristic information of rainstorm

郑州“2021.7.20”暴雨发生后,暴雨特征信息描述成为网络热点,各种观点引起公众诸多误解。从暴雨特征信息的空间尺度、时间尺度、极端暴雨重现期等方面梳理信息传播中的网络乱象;从暴雨特征时空要素的规范性、暴雨原始监测数据与特征信息的共享程度、暴雨重现期的科学性等角度探讨乱象发生的原因。主要结论包括:及时、规范、精准的信息发布是应对不实信息传播的最好方式;水利、气象、应急等部门应当正视暴雨特征信息传播中存在的问题,夯实工作基础,优化协作机制,及时发布权威信息。

After the occurrence of"2021.7.20"rainstorm in Zhengzhou,the description of rainstorm character-istic information becomes the focus of the network,and all kinds of views that cause public misunderstand-ings fill the network.This paper collects the chaotic information spreaded on the Internet from three aspects:the spatial scale,the temporal scale and the recurrence period of extreme rainstorm,discusses the causes of the chaos from the aspects of the standardization of temporal and spatial elements of rainstorm characteristics,the sharing degree of rainstorm original monitoring data and characteristic information,and the science of rain-storm recurrence period.The main conclusions include:Information distribution should be timely,standard-ized and accurate,which is the best way to deal with the dissemination of false information.Some depart-ments,such as water resources,meteorology and emergency management,should correctly analyze the prob-lems existing in the dissemination of rainstorm characteristic information,consolidate the work foundation,op-timize the cooperation mechanism and publish authoritative information in time.
