WXS21

This report describes the results of a first of its kind, nationwide survey of Spanish speakers on severe weather in the United States. The 2021 Severe Weather and Society Spanish Survey (WXS) was designed and administered by Institute for Public Policy Research and Analysis (IPPRA) at the University of Oklahoma. While it is the first time IPPRA has conducted this survey, the English equivalent is an annual series (see Silva et al. 2017, Silva et al. 2018, Silva et al. 2019, Krocak et al. 2020, and Krocak et al. 2021 for information on WX17, WX18, WX19, WX20, and WX21 respectively). WXS was fielded June 9 – June 17, 2021, using an online questionnaire that was completed by 1,032 U.S. adults (age 18+) that were recruited from an Internet panel. In order to complete the survey, respondents had to indicate that they speak Spanish well or very well. In addition to asking respondents many of the same questions as the WX surveys, the WXS survey also asked respondents a number of experimental questions to test the way risk and probability are communicated to Spanish speakers. Like the WX surveys, the WXS measured public trust in the National Weather Service (NWS), extreme weather and climate risk perceptions, risk literacy, interpretations of probabilistic language, and interpretation of longer-range severe weather forecasts (like those from the NOAA Storm Prediction Center). This report presents an overview of methodology of the survey data collection and a reproduction of the survey instrument with means and frequencies for the questions that elicited numeric responses. The University of Oklahoma provided funding for all data collection. NOAA’s Weather Program Office through the U.S. Weather Research Program provided funding for survey design and data analysis

本报告呈现了全美范围内针对美国西班牙语使用者开展的首例极端天气主题调查成果。2021年极端天气与社会西班牙语调查（WXS）由俄克拉荷马大学公共政策研究与分析研究所（Institute for Public Policy Research and Analysis，IPPRA）设计并执行。尽管这是IPPRA首次开展此类调查，但其英语对应版本为年度系列调查（相关调查信息分别参见Silva等人2017、2018、2019年及Krocak等人2020、2021年的研究，对应WX17、WX18、WX19、WX20及WX21调查）。WXS的实施周期为2021年6月9日至6月17日，采用在线问卷形式，共回收1032名年龄18岁及以上的美国成年受访者的有效问卷，受访者招募自互联网样本面板。受访者需表明自身西班牙语水平良好或极佳，方可完成本次调查。除沿用WX系列调查的多数问题外，WXS还增设了若干实验性问题，用于测试针对西班牙语使用者的风险与概率沟通方式。与WX系列调查一致，WXS同样测量了公众对美国国家气象局（National Weather Service，NWS）的信任度、极端天气与气候风险感知、风险素养、概率语言解读能力，以及长期极端天气预报（如美国国家海洋和大气管理局风暴预测中心发布的预报）的解读能力。本报告概述了调查数据收集的方法论，并附上了调查工具的复现内容，同时给出了所有数值类问题的均值与频数分布。本次数据收集的全部经费由俄克拉荷马大学提供，调查设计与数据分析的经费则由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）天气项目办公室通过美国天气研究计划提供。
