"More than 25 years later, despite the dubious results of past research and other concerns raised by critics, the Department of Homeland Security is attempting to establish a hurricane modification program of its own, but NOAA appears unwilling to provide the critical support the DHS program requires.
...The goals of the workshop were to understand and evaluate new approaches for modifying hurricanes, which DHS regards as a threat to national security following the death and destruction wrought by hurricanes Katrina and Rita in 2005, and to decide how best to move forward.
Despite NOAA's hosting of the workshop, NOAA has rebuffed subsequent efforts by DHS to involve NOAA in its hurricane modification research, according to high-level sources within NOAA's Office of Oceanic and Atmospheric Research.
...So far, the lack of interest from NOAA, the government agency responsible for issuing official forecasts of hurricanes through its National Hurricane Center, has not stopped DHS from developing a plan for hurricane modification research and testing. William Laska, program manager for DHS's Advanced Research Projects Agency (HSARPA), which is spearheading the department's hurricane modification efforts, outlined a suggested road ahead at an April American Meteorological Society meeting on weather modification.
The plan envisions three research tasks beginning toward the end of 2010 and ending in early 2016: Evaluation of storm modification approaches via computer model simulations, development of concepts for potential field experiments, and full-scale testing of one or two of the most viable concepts. Total cost to carry out the plan was estimated at $64.1 million."
