U.S. severe convective storms have grown to represent a 10-billion-dollar annual peril for the insurance industry, and their accurate prediction remains a challenging task. In addition, we now live in a world where these extremes are changing in frequency and location. For example, recent research has shown an upward trend for tornadoes in the Mid-South, and a decreasing trend in the notorious "Tornado Alley" of the Great Plains. Changes in the climate, along with changes in the human-built environment, are drastically shifting the landscape of risk associated with natural hazards.
