WX18

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 second survey in the annual series (see Silva et al., 2017 for information on WX17). WX18 was fielded July 6-11, 2018 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, which was designed to establish baseline measures of the extent to which U.S. adults receive, understand, and respond to severe weather forecasts and warnings, WX18 was designed to continue and, in some cases, refine the measurement of these concepts. Additionally, WX18 measured public trust in the National Weather Service (NWS), extreme weather and climate risk perceptions, risk literacy, interpretations of probabilistic language, and response efficacy.

强天气与社会调查（Severe Weather and Society Survey, WX）由俄克拉荷马大学风险与危机管理中心（Center for Risk and Crisis Management, CRCM）设计并实施。本调查为年度系列调查的第二期（关于WX17的详细信息可参见Silva等人2017年的研究）。WX18于2018年7月6日至11日开展，采用在线问卷形式，共回收3000名18岁及以上美国成年人的有效问卷；受访者招募自匹配美国人口普查统计人口特征的互联网招募面板。
WX17旨在建立美国成年人接收、理解并响应强天气预报与预警程度的基线测量指标，WX18则延续了这一研究方向，并在部分维度上优化了上述概念的测量方式。此外，WX18还测量了公众对国家气象局（National Weather Service, NWS）的信任度、极端天气与气候风险感知、风险素养、对概率性表述的解读能力以及响应效能。
