Day 151: 2010 Tornado Deficit

Day 151

VORTEX II was once again forced to call a down day because the atmosphere just wasn’t willing to cooperate. Fortunately for the crew, tomorrow appears to hold more promise for thunderstorms in their general area.

So, with all these down days recently, I wondered how the 2010 tornado season has compared to the tornado seasons of years past. I’ve previously mentioned that 2010 has been a below normal year for tornadoes through the first three months of the year. Now that another (almost) 2 months have passed, and VORTEX II has begun, where do things stand now?

In the image above (which I’ve described previously here), the average over the last five years is marked in grey, and actual events for this year are plotted in red. As you can see, we are still nearly 200 tornadoes below the average over the last five years. This is not a good sign for the VORTEX II crew. Here’s to hoping the next few days and weeks are better for researchers.
