Description :
Records of extremely damaging storms in the United States during the years 1949-2006 were assessed to define their temporal distribution. A change in climate due to global warming may lead to more weather extremes, including storms. The aim of this study was to learn if the frequency of highly damaging storms had increased. The number of storms at both loss levels has increased dramatically since 1990, and storm-related losses also increased. Much of the increased loss and greater storminess was due to several recent hurricanes. The AA. speculate about the cause/s of changes in storms and losses : storm measurements and data collection have improved over time; natural variations in climate or a shift in climate due to global warming; society more vulnerable to storm damages.
