Because not many people know about it
By Paul Homewood
It’s time to debunk the annual tornado hoax from NOAA:

According to NOAA’s most recent annual report, the frequency of U.S. tornadoes has steadily increased since the 1950s. For the average reader, this is obviously due to global warming, which we all know makes the weather more extreme!
No report mentions that there are more tornadoes now because of better technology and reporting procedures, not because there are more occurrences. This is a guide that NOAA published a few years ago, which has now mysteriously disappeared from their website. Thanks to Wayback, we can still see it.
One of the main difficulties with tornado records is that tornadoes, or evidence of tornadoes, must have been observed. Unlike rainfall or temperature, which can be measured with fixed instruments, tornadoes are short-lived and unpredictable. If a tornado occurs in an uninhabited or uninhabited area, it should not be documented. Many significant tornadoes may not enter the historical record Tornado Hallway it was sparsely populated in the 20th century.
Much of the early work on tornado climatology in the United States was done by John Park Finley in his book Tornadoes, published in 1887. While some of Finley’s safety guidelines have been criticized as dangerous practices, the book remains a seminal work in tornado research. The University of Oklahoma has made a PDF copy of the book available at Tornado John Finley.
Today, almost the entire United States is pretty much populated, or at least covered by NOAA’s Doppler weather radar. Even if a tornado is not actually observed, modern damage assessments by National Weather Service personnel can distinguish if a tornado caused damage, and if so, how strong the tornado was. The disparity between tornado records from past and current records contributes much uncertainty to questions about the long-term behavior or patterns of tornado occurrence. Improved tornado observation practices have led to an increase in the number of weaker tornadoes, and in recent years. EF-0 tornadoes have become more common in the total number of reported tornadoes. In addition, to this day many small tornadoes can still go undocumented in places with less population or inconsistent communication facilities.
With increased National Doppler radar coverage, increased population, and greater attention to tornado reporting, the number of tornado reports has increased over the past several decades. This can create a misleading view of the increasing trend in tornado frequency. To better understand the variation and trends in the frequency of tornadoes in the United States, the total number of EF-1 and stronger, as well as strong to severe tornadoes (categories EF-3 to EF-5 on the Enhanced Fujita scale) can be analyzed. . These tornadoes would have been reported even decades before the widespread use of Doppler radar and practice led to an increase in tornado reports. The bar chart below shows there is a small trend in the frequency of stronger tornadoes over the past 55 years.

In fact, there was a sharp decline in the number of strong tornadoes through 2014, rather than the “small trend” noted by NOAA.
We now have complete data for 2023, so I can extend the two graphs above:

The picture has changed a little since 2014. There is still a little long-term trend in EF-1s and over, but the number of EF-3s remains at a lower level than before 2000. The latest data confirms NOAA’s conclusions from 2015.
There were no EF-5s last year, or so far this year. The last one was the Moore tornado in 2013. There are an average of two EF-5s per year for three years. The longest previous EF-5 absence was between 1999 and 2007.
Also, there were only two EF-4s last year. only 2005 and 2018 have less.
The evidence clearly shows that tornadoes have become less intense since reliable records began in 1970, but NOAA wants you to believe otherwise.
It is difficult to describe the NOAA report of the tornado as anything other than fraudulent.
