Across North America, hailstorms are responsible for over $10 billion dollars in annual property damage. The increase in the impact of hailstorms has outpaced advances in detection, forecasting, and mitigation. The National Science Foundation, the National Center for Atmospheric Research and the Insurance Institute for Business & Home Safety are organizing the first North American Workshop on Hail and Hailstorms. The workshop will bring together public and private stakeholders to discuss the current state of the science regarding all facets of this peril and provide a look to the future. The workshop will be held at the NCAR Center Green 1 (CG1) campus, 3080 Center Green Drive, Boulder, Colorado.


The workshop will focus on the following topics:

  • Convection & hail in a changing climate
  • Hail climatology & risk
  • Hail damage, losses, and mitigation
  • Hail detection & forecasting
  • Microphysics and dynamics of hailstorms

The workshop will contain a blend of invited speakers, expert panel discussions, traditional symposia and poster sessions related to the topics listed above over the course of three full days.


The workshop registration fee is $150, due before July 1, 2018. Late registration is $250. Registration
