The head of The Tornado Project has been very busy indeed. Bravo on your work good sir!

On the 22nd March, meteorologist Thomas Grazulis posted four rather interesting graphs relating to data regarding March Tornadoes from 1875 – 2019 on his Twitter account.

With quotes from Grazulis relating to them, find the four graphs he produced below – please note find original tweets at the bottom of the article. 

Tornado deaths in March outbreaks – 1875 – 2019

“Death totals are down since the 1950, especially this day in 1952. Reason – fewer violent tornadoes? Fewer major outbreaks? Forecasting and warnings? Pacific Ocean patterns? Problem understanding many variables.”

Very significant [Tornado] outbreaks in March – 1875 – 2019

“The number of “very significant” outbreaks has not changed much. Definition that gives clearest picture across 150 years: at least two F3-5 tornadoes, and 50+ miles of upper EF2 to F5 path miles. Subjective? oh yes, but the best I can come up with.”

Path length in March [Tornado] outbreaks – 1875 – 2019

“Recent “very significant” total path miles are a little less, but maybe they just are not as violent. No way of telling! There have been quiet periods in the past. Current low number of March events is not unique. Last big one was in 2012.”

Killer Tornadoes in March “outbreaks” – 1875 – 2019

“The number of killer tornadoes in outbreaks has become very variable, as have deaths. Bad luck play a big part now, as it did this year. Below are all 69 March outbreaks. There have been about 630 “outbreaks” for all months since documentation started in 1873″

Grazulis also produced a table – on Twitter (CLEVER!) – regarding to killer Tornadoes since March 1873. Find his table in the tweets below..
