WX20

The Severe Weather and Society Survey (WX) was designed and administered by the Center for Risk and Crisis Management (CRCM) at the University of Oklahoma. This is the fourth survey in the annual series (see Silva et al. 2017, Silva et al. 2018, and Krocak et al. 2019 for information on WX17, WX18, and WX19). WX20 was fielded June 10 – July 19, 2020 using an online questionnaire that was completed by 3,000 U.S. adults (age 18+) that were recruited from an Internet panel that matches the characteristics of the U.S. population as estimated in the U.S. Census. Following WX17, WX18, and WX19, which were designed to establish baseline measures of the extent to which U.S. adults receive, understand, and respond to severe weather forecasts and warnings, WX20 was designed to continue and, in some cases, refine the measurement of these concepts. Additionally, WX20 measured public trust in the National Weather Service (NWS), extreme weather and climate risk perceptions, risk literacy, interpretations of probabilistic language, and perceptions the accuracy of weather information.极端天气与社会调查（WX）由俄克拉荷马大学风险与危机管理中心（CRCM）设计并实施。本调查为该年度系列调查的第四期，关于WX17、WX18及WX19的详细信息可参阅Silva等人2017年、2018年以及Krocak等人2019年的相关研究。WX20于2020年6月10日至7月19日通过线上问卷开展调研，共回收3000名18岁及以上美国成年人的有效问卷；受访者招募自与美国人口普查所估算的全美人口特征匹配的互联网样本库。此前的WX17、WX18及WX19旨在建立美国成年人接收、理解极端天气预报与预警的情况及其应对行为的基线测度，WX20则延续了这一研究方向，并在部分维度上优化了相关概念的测量方式。此外，WX20还调研了公众对美国国家气象局（NWS）的信任度、极端天气与气候风险认知、风险素养、概率性语言解读能力，以及对气象信息准确性的主观判断。
