Hailstorms have grown more destructive in recent years, causing up to $10 billion per year in damage. The reasons range from larger homes being built, to more homes being built in vulnerable places, to the rising costs of roofing materials, according to a recent Washington Post article.
The first North American Workshop on Hail and Hailstorms is happening this week (August 14- 16) in Boulder, Colorado. The group will discuss the rising costs of hail damage, and 200 experts from the fields of meteorology, engineering, economics and insurance are attending. These experts will work together to better detect hail; the microphysics and dynamics of hailstorms; the cost of damage and how to mitigate it; and the likely effects of a changing climate on hailstorms.
