Summer ozone loss over central United States

Based on weather radar observations and an atmospheric model, researchers find that approximately 2,000 summer storms above the US Great Plains inject water vapor into the stratosphere, where temperatures were cooler than previously measured, and a model predicts that the probability of converting inorganic chlorine to its free radical form increases at these temperatures, likely initiating a process of ozone loss from the protective ozone layer. - Read at PNAS
