“…Previous studies have acknowledged that nonconvective wind events harm as many individuals as winds associated with severe thunderstorms or hurricanes (Mortimer and Kane 2004;Lacke et al 2007;Ashley and Black 2008;Schmidlin 2009;Knox et al 2011a). Therefore, the need exists to further examine the public's perception of current wind-specific products and their willingness to react to these alerts.…”

Weather products generated by the National Weather Service (NWS) are crucial for communicating information about weather events. However, it is unclear if the public understands those that exclusively involve wind terminology or the risk posed by nonconvective wind events. To further investigate these questions, we surveyed 373 members of the public from Georgia and Virginia who regularly obtain weather information from two weather blogs in each of the states. Participants completed an online survey designed to evaluate their familiarity with NWS wind products (high wind warning and wind advisory), perceived wind speed thresholds associated with these products, willingness to change plans based on these products, and finally, "weather salience"-the importance participants place on weather information.It was found that our participants scored higher on the weather salience measure compared to previous studies that examined the general public. In both states, these weather-attentive individuals defined high wind warnings (57.5%) and wind advisories (31.8%) in terms of impacts to their daily lives. Respondents also reported that they would be more likely to alter their plans for a high wind watch compared to a wind advisory, providing evidence of a spectrum of understanding about the NWS wind products. Although various NWS initiatives are currently experimenting with the watch/warning/advisory system and impact-based messaging, this study identifies the need to continue and expand this line of research to include all weather hazards (those convective and nonconvective in nature).

“…These results support the hypothesis of Ashley and Black (2008) and highlight the need for further research into all types of windstorm casualties. Recently, research has begun to uncover the factors-climatological, meteorological, and societal-that lead to potentially deadly nontornadic windstorms (e.g., Ashley and Mote 2005;Lacke et al 2007); however, a sustained and enhanced focus on these windstorms in the meteorological and hazard communities is necessary for future mitigation success. Mass casualty events due to aviation accidents may skew overall results toward these specific, nonterrestrial events; thus, these fatality events are excluded from the subsequent analysis and are discussed in Sect.…”

A database was compiled for the period 1977-2007 to assess the threat to life in the conterminous United States from nontornadic convective wind events. This study reveals the number of fatalities from these wind storms, their causes, and their unique spatial distributions. Nontornadic convective wind fatalities occur most frequently outdoors, in vehicles including aircraft, or while boating. Fatalities are most common in the Great Lakes and Northeast, with fewer fatalities observed in the central United States despite the climatological peak in severe thunderstorms in this region. Differences in fatality locations between tornadoes and nontornadic convective wind events highlight the unique combination of physical and social vulnerabilities involved in these deaths. Understanding these vulnerabilities is important to future reduction of nontornadic convective wind fatalities.

“…Although less familiar than their convective counterparts (i.e. thunderstorms, tornadoes, tropical cyclones) in many parts of the world, these wind events occur in a number of regions globally in the mid‐latitudes, including: the East Coast of North America (Ashley and Black 2008), the Great Lakes region of the USA and Canada (Figure 1; Lacke et al. 2007; Niziol and Paone 2000), the northern Great Plains of the USA (Kapela et al.…”

Non‐convective high winds are a damaging and potentially life‐threatening weather phenomenon that occurs in the absence of thunderstorms, tornadoes and tropical cyclones. The vast majority of non‐convective high wind events develop in association with extratropical cyclones in mid‐latitude regions. Interest in non‐convective high winds is growing due to their societal impact, gaps in the scientific understanding of the triggering mechanisms for these events, and possible future changes in their frequency and intensity caused by climate change. In this article, non‐convective high winds are examined first in terms of their historical and cultural significance and climatological characteristics. Then, four possible mechanisms for the development of non‐convective high winds in extratropical cyclones are discussed and critiqued: topography; the isallobaric wind; tropopause folds associated with stratospheric intrusions and dry slots; and sting jets associated with marine frontal cyclones. Evidence for past and future trends in non‐convective high wind event frequency and intensity is also briefly examined. New avenues for future work in this emerging area of research are suggested that unite applied and basic research as well as climatological and case‐study perspectives.
