Talk:TORRO scale

About the Torro Class paragraph

It seems biased towards the UK when most tornadoes occur in the US. Is the Torro Scale used more commonly in the UK than other places? —Preceding unsigned comment added by JasontheFuzz (talk • contribs) 12:53, 29 April 2008 (UTC)

Confusing assertions
The closing paragraph of this article is confusing at best, and erroneous at worst.

To whit : ''winds in a tight rotating circulation, such as a tornado, are generally 1.5 times more destructive than straight line winds of the same speed. For instance, a 300 mile per hour wind in a tight circulation will produce about the same amount of damage as a 450 mile per hour straight line wind.''

The problem is that the second sentence in this paragraph is mathematically at odds with the first.

Since the destructive index of a wind is known to increase with the square of it's velocity, i.e., it follows the the same laws of kinetic energy as any moving object, we would predict that increasing a straight line wind from 300 to 450 mph would make it 2.25 times as destructive, not 1.5. And increasing the speed of any wind by the square root of 1.5 (a value of approximately 1.225) would be sufficient to increase it's destructiveness 1.5 times.

 * Although vortical winds do have more of an effect on surfaces such as structures and vegetation, the effect is chaotic and cannot be generically quantified as asserted in the article. It's unsourced as one would expect.  It's also not really necessary to be added, and if it is mentioned, it's placement below the article is not the place for it.  Given these reasons, the assertion has been removed.  Evolauxia (talk) 17:15, 9 October 2008 (UTC)

T11
What is the T11 effects like? 'Incredible phenomena will occur'? A T11 tornado is a tornado with winds in excess of 290mph. So essentially, think of a particularly powerful F5/EF5 tornado. Storms such as the Hackleburg Tornado of 2011 may serve as an example of a T11 tornado and that storm leveled large factories and tore concrete from the foundations of buildings.

I have added several tags to this article; please address these
This article contradicts the article on the Enhanced Fujita Scale that says that 5 countries use it (The U.S., Canada, France, China, and Mongolia). This article says only two countries (The United States and Canada) use the scale. I have added a “needs update” tag and a “contradicts another article” tag for that reason. Please address this article and/or the EF scale article. I am fixing to add a “citation needed” tag to the claim that China and Mongolia use the EF scale in the EF scale article. 108.147.10.49 (talk) 19:42, 11 December 2023 (UTC)
