在美国，龙卷风和其他严重的雷暴现象每年造成的财产损失往往与飓风一样多，而且往往造成更多的死亡（见http：//www.nws.noaa.gov/om/hazstats.shtml）。2008年，截至12月中旬，共有2176份龙卷风初步报告，截至9月有1600份“实际计数”（删除重复报告），是过去半个世纪的最高总数（图1）。大众媒体对这些事件进行了广泛报道，专家们也被大量的解释请求所淹没，包括与人为全球变暖的可能联系。虽然最近的研究已经深入了解了全球变暖与龙卷风和严重雷暴强迫之间的联系，但这些关系大多尚未探索，主要是因为观测和数值模拟龙卷风的挑战。
Tornadoes and other severe thunderstorm phenomena frequently cause as much annual property damage in the United States as do hurricanes, and often cause more fatalities (see http://www.nws.noaa.gov/om/hazstats.shtml). In 2008, there were 2176 preliminary tornado reports logged through mid-December, with 1600 “actual counts” (duplicate reports removed) through September, the highest total in the past half century (Figure 1). The mass media have covered these events extensively, and experts have been deluged with requests for explanations, including possible links to anthropogenic global warming. Although recent research has yielded insight into the connections between global warming and tornado and severe thunderstorm forcing, these relationships remain mostly unexplored, largely because of the challenges in observing and numerically simulating tornadoes.
