Ok, for all the global warming naysayers – apparently we are truly changing our environment and its not happening over tens of thousand of years but right here on “hump day” in da middle of the week.

Nov. 26, 2008 — As if getting through “hump day” could get any tougher, new research shows that the middle of the week is the worst time for lightning.

There are 10-20 percent more strikes on Wednesdays and Thursdays than there are on the weekends. The weekly spike in dangerous weather appears to occur in the summer in the southeastern part of the United States as a result of air pollution.

Lightening strikes and the Diesel fuel coorelation

“The one thing that seems to change most during the week is heavy truck traffic,” Thomas Bell of NASA’s Goddard Space Fight Center in Maryland said. “It starts rising on Monday, then peaks around Wednesday or Thursday. We don’t know why that would be, but it’s a pretty dramatic pattern.”

In previous research, Bell found that summer precipitation in the southeastern United States follows a similar pattern. He suspects that microscopic particles spewed from trucks’ diesel engines act as seeds for forming water droplets in clouds. With more seeds in the air more droplets form, but they are smaller.

Rising bubbles of warm air can easily loft small droplets high into the atmosphere, forming huge, towering thunderheads. And if the droplets get high enough, they freeze.
