Stormy weather throughout the central part of the United States recently has had many reporters and meteorologists ask the question, "Why? Why so many powerful storms day after day in the same general area?"

To be sure, it has been a perfect storm of storms: a southwest to northeast jet stream riding over the top of southerly and southeasterly winds blowing out from an early-season heat wave across the Deep South. There is a natural knee-jerk reaction to lay blame on something. Climate change/global warning is often offered as a reason for the extreme weather, and there may well be a relationship between the storms and increased heat and humidity.

However, the main reason for the stormy weather is the shape of the wind fields. It is premature to stack too much blame for one weather event, even one lasting several days, on greenhouse gasses. Extreme weather is not new, even if it has been increasing in recent decades.
