Lungs getting a breather from ozone

"There's been a sort of semi-permanent area of low pressure over the Great Lakes for most of the summer season, and as the wind spins around that low, we've just been getting cloudier and cooler weather than normal," said Bill Ryan, a meteorology professor at Pennsylvania State University and consultant to the EPA. "The other thing that's going on is, our ozone concentrations have fallen over the past five or six years. What we call the regional background ozone that comes into our big cities from the west with the prevailing winds has been significantly reduced."
