We are pleased to introduce WUWT’s newest addition, the WUWT Tornado Reference Page. We would like to dedicate this page to Dana Nuccitelli, of Skeptical Science infamy, who single-handedly managed to get Keith Kloor, Roger Pielke Jr., William Connolley, Thomas Fuller, Harold Brooks and countless others, all on the same side of a debate. At least most of us can agree that disparaging good scientists with unsupported assertions about “misleading the American public”, is not helpful to any side or anyone within this debate, unless of course you are a paid mudslinger.
Anyways, the WUWT Tornado Reference Page offers a combination of Current Convective Watches, Storm/Tornado Reports, 1 and 2 Day Outlooks and Historical Data on the Strength, Frequency and Location of tornadoes in the United States. The United States “experiences approximately 75 percent of the world’s known tornadoes”, however there weren’t graphs or graphics identified for the approximately 25% of global tornadoes that occur outside the U.S. If you are aware of any Global tornado graphs graphics, or have suggestions for additional U.S. content, please post them in comments.
Below are a few observations from the new WUWT Tornado Reference Page:
U.S. Inflation Adjusted Annual Tornado Trend and Percentile Ranks show that the current tornado count of 790 for 2013 is 154 tornadoes below the historical minimum of 944, 497 tornadoes below the 50th percentile of 1287 and 1089 tornadoes below the historical maximum 1879:
Tornado counts are Inflation Adjusted “because the increase in tornado reports over the last 54 years is almost entirely due to secular trends such as population increase, increased tornado awareness, and more robust and advanced reporting networks.” NOAA – Storm Prediction Center However, for reference, the following are non-Inflation Adjusted Preliminary U.S. Annual Tornado Trend From National Weather Services Local Storm Reports. Currently the Preliminary U.S. Tornado Count for 2013 year to date is 934, which is 544 tornadoes below the 2005 – 2012 average of 1478 and 134 tornadoes below the 2012 low of 1068 tornadoes.
When looking over a longer time frame U.S. EF1-EF5 Tornadoes;
U.S. Strong to Violent EF3-EF5 Tornadoes;
and Normalized US Tornado Damage;
“tornadoes have not increased in frequency, intensity or normalized damage since 1950, and there is some evidence to suggest that they have actually declined.” as Roger Pielke, Jr. noted in his recent testimony at a congressional Sub-Committee hearing on “A FACTUAL LOOK AT THE RELATIONSHIP OF CLIMATE AND WEATHER”. You can either believe the data, your own eyes and Roger, or you can believe Dana Nuccitelli and his claim that unamed “Tornado experts say @RogerPielkeJr and Richard Muller are misleading the American public”…

Please note that WUWT cannot vouch for the accuracy of the data within the Reference Pages, as WUWT is simply an aggregator. All of the data is linked from third party sources. If you have doubts about the accuracy of any of the graphs on the WUWT Reference Pages, or have any suggested additions or improvements to any of the pages, please let us know in comments below.
