Dear Tom,
Another active hurricane season has ended. As you have said many times,
hurricanes are fueled by warm, moist air, so why can't they be stopped by
chilling the eye with ice?

Dear Matthew,
Dr. Chris Lansdea, Director of the National Hurricane Center's Research
Division, has written extensively on the subject of hurricane modification.
He states categorically that "... Hurricane modification by any means is an
exercise in futility and impracticality. Consider the scale of what we are
talking about. The critical region in the hurricane for energy transfer is
under or near the eye wall," an area of about 2,000 square miles. Allowing
for storm movement and uncertainty in its track, the "cool patch" expands to
31,000 square miles. That's 55 percent of the area of Illinois, and it is
simply impossible to chill such a huge area.
WGN-TV Chief Meteorologist Tom Skilling and the WGN Weather Center staff provide daily coverage of weather in the Chicago area.
