暴露在酷热或热浪中，既是对公共健康的威胁，也是对环境健康的威胁。由于预测全球环境变化将导致一些区域的气温进一步上升，因此必须了解热浪的时空影响，以便将风险降至最低。要了解热浪的影响，不能只看空间和时间的温度状况，还要考虑关键的热浪特征：持续时间、大小、强度、频率和影响区域。要了解热浪事件的后果，关键是要基于这些特征的累积影响来分析此类极端事件。这项研究在整个美国大陆进行，旨在绘制和分析热浪特征的这种累积影响。在空间上定义了每年5-9月期间的热浪。利用持续性分析和发展一个新的指数(综合热浪特征指数(CHCI))，我们可以确定热浪持续暴露和影响的区域。结果显示，美国各地在热浪暴露和影响热浪特征方面存在很大差异。纵观大部分分析，可以看到东西方在模式上的明显差异。总体而言，这些工作展示了不同但相同的热浪特征如何以及在哪里影响了美国。这项工作的信息可以与人口统计和健康指标相结合，以更好地确定热浪的易感性，从而为更好的管理决策提供信息。
Exposure to extreme heat, or heat waves, represents a public health threat as well as an environmental health threat. With projections for further increases in temperature in some regions, resulting from global environmental change, it is important to understand the spatiotemporal impacts of heat waves in order to minimize risk. To understand heat wave impacts, one cannot look solely at the spatial and temporal temperature regimes but much also consider key heat wave characteristics: duration, size, magnitude, frequency, and region of impact. To understand the consequences of heat wave events, it is critical to analyze such extreme events based on the cumulative impacts of these characteristics. This study, which is conducted across the whole of the continental United States, looks to map and analyze such cumulative impacts of heat wave characteristics. Heat waves were spatially defined for the period of May–September of each year. Using persistence analyses and the development of a new index (combined heat wave characteristics index (CHCI)), we can define regions of consistent heat wave exposure and impact. Results show that there are large differences across the United States in terms of heat wave exposure and impacting heat wave characteristics. Across much of the analysis, a clear east versus west difference in patterns is seen. Overall, such work shows how and where differing but covarying heat wave characteristics impact the United States. Information from this work can be combined with demographic and health metrics to better pinpoint susceptibility to heat waves—and therefore inform better management decisions.
