Department of Homeland Security Hurricane Modification Workshop Report

In view of these realities, the Department of Homeland Security (DHS) with the organizational assistance of the National Oceanic and Atmospheric Administration (NOAA)/Global Systems Division of the Earth Systems Research Laboratory sponsored a workshop on hurricane modification at the David Skaggs Research Center in Boulder, Colorado February 6-7, 2008. This action is consistent with the Homeland Security Act of 2002, the Department of Homeland Security (DHS) mission to respond to threats and hazards to the nation and the Science and Technology Directorate (S&T) goal to accelerate delivery of enhanced technological capabilities to meet requirements and fill capability gaps to support DHS agencies in accomplishing their mission. The focus of the workshop was to:

  • Identify viable hurricane modification hypothesis that warrant further study
  • Understand hurricane physical processes including their initial development, mechanics, life cycle, instabilities and responses to outside dynamics and forces
  • Understand DHS specific concerns regarding hurricane threats to life and property caused by wind, rain and storm surge
  • Define potential DHS-specific hurricane modification factors, requirements and risks (i.e. pre-development modification, track changes, intensity change)
  • Address projected effort/cost/viability/time-lines for hurricane modification implementation
  • Recommend a path forward 
  • Limited scale field tests:
    • Salt Seeding Tests
    • Carbon Black Aerosol (CBA)
    • Upper Ocean Cooling
    • Ion Generators
    • Seeding
    • Monolayer Films
