Scientists have made a breakthrough in man's desire to control the forces of nature – unveiling plans to weaken hurricanes and steer them off course, to prevent tragedies such as Hurricane Katrina.The damage done to New Orleans in 2005 has spurred two rival teams of climate experts, in America and Israel, to redouble their efforts to enable people to play God with the weather. Under one scheme, aircraft would drop soot into the near-freezing cloud at the top of a hurricane, causing it to warm up and so reduce wind speeds. Computer simulations of the forces at work in the most violent storms have shown that even small changes can affect their paths – enabling them to be diverted from major cities.But the hurricane modifiers are fighting more than the weather. Lawyers warn that diverting a hurricane from one city to save life and property could result in multi-billion dollar lawsuits from towns that bear the brunt instead. Hurricane Katrina caused about $41 billion in damage to New Orleans.Hurricanes form when air warmed over the ocean rises to meet the cool upper atmosphere. The heat turns to kinetic energy, producing a spiral of wind and rain. The greater the temperature differences between top and bottom, and the narrower the eye of the hurricane, the faster it blows.Moshe Alamaro, of the Massachusetts Institute of Technology (MIT), told The Sunday Telegraph of his plans to "paint" the tops of hurricanes black by scattering carbon particles-either soot or black particles from the manufacture of tyres-from aircraft flying above the storms. The particles would absorb heat from the sun, leading to changes in the airflows within the storm. Satellites could also heat the cloud tops by beaming microwaves from space....To read more go to:
