Lull in Severe WeatherDecember 6th, 2012 at 9:31 pm by Jonathan Conder under Weather
Either people are heeding the warnings from the National Weather Service when it comes to tornadoes, or mother nature is taking a break. Above is a graph showing the maximum number of days between tornado fatalities in the United States, from Greg Carbin of the Storm Prediction Center.
This is not the longest stretch, this was 197 days, ending on February 28th, 1987 and yes, fatal tornadoes can happen any time of the year, even in February.
Actually, the 2012 severe weather season started out very strong, but turned anemic very quickly. Check out this chart:
This is a plot of the 2011 and 2012 tornado seasons compared to average. Notice that 2011 ended with almost 400 tornadoes above average and 2012 will likely end the year with almost 400 tornadoes below average.
That being said, if global warming or climate change is causing more violent storms, where are they?
