During the scorching summer months an afternoon rainstorm can be a common and refreshing sight.

But for residents in the southeastern United States, a new NASA study has found, these storms are more intense during the work week than on the weekends. This trend, scientists believe, is driven by pollution that also increases during the work week, from sources like traffic, businesses and factories.

Scientists have long suspected a link between work week pollution and rainfall, but, after analyzing rainfall and pollution data, the connection was clear.

As this new video from NASA shows, it seems that we may be having a greater impact on the weather than we ever knew.
