Remember how the deadly tornado took a jog to the southeast resulting in the deaths of professional meterologists?

There is now a way of tracking the frequency and CHANGE in tornado patterns. This is an interesting way to approach and I am grateful this is a focus now, BUT, the REASON for that jog is related to 'oscillation' within the troposphere itself.

This is an excellent tool. Pure genius.

“Not surprisingly, (click here) the lion’s share of storms travel in a northeastern direction along with the prevailing winds (and carry F5 storms at double the rate as the other quadrants),” Nelson wrote on the blog. “I was interested in seeing just how great a proportion actually do. Beyond that, I was interested in seeing regional trends where historic storms have bucked that NE trend and traveled some other direction.”

Nelson said he got the idea from New York-based meteorologist Robert Staskowski who wrote about the  ”[carving] up the country into tornado warning zones.” These maps, Nelson told io9, are part of his effort to do just that — create tornado warning zones that have more educated input on the twister’s direction.
