One analysis generally found no evidence of significant changes in wind speed <br />distribution. Othertrends in severe storms, including the numbers of hurricanes and the intensity and <br />frequency of tornadoes, hail, and damaging thunderstorm winds are uncertain. Since the impact of <br />more frequent or intense storms can be largerthan the impact of average temperature, climate <br />scientists are actively researching the connections between climate change and severe storms <br />(National Climate Assessment Development Advisory Committee, 2013). <br />Vulnerability <br />Vulnerability to injury from all kinds of windstorms decreases with adequate warnings, warning time, <br />and sheltering in a reinforced structure. Vulnerability to structures depends upon construction of the <br />building and infrastructure. Residents of mobile homes are more vulnerable to fatality or injury from <br />windstorms because mobile homes are not able to withstand high winds as well as other structural <br />Page 147 <br />
