TORRO claims it differs from the Fujita scale in that it is "purely" a wind speed scale, whereas the Fujita scale relies on damage for classification, but in practice, damage is utilised almost exclusively in both systems to infer intensity. That is because such a proxy for intensity is usually all that is available, although users of both ...
The TORRO scale, created by the Tornado and Storm Research Organization (TORRO), was developed in 1974 and published a year later. The TORRO scale has 12 levels, which cover a broader range with tighter graduations. It ranges from a T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes.
The tornado earned an F0 on the fujita, T1 on the torro scale, and IF0+ on the IF scale [3] IF1: January 30 2021 Turkey Hatay Province: Vakıflı A Restaurant area sustained moderate damage. Garage roof torn off, roofs damaged & a pine tree were snapped. The tornado earned an F1 rating on the fujita scale, and an IF1 rating on the IF scale. [3 ...
Aerial photography and isoline surveys by Fujita showed that entire rows of brick homes were swept away and sustained F5 damage. Wind-rowing of debris occurred in nearby fields and very intense damage was reported to steel-reinforced schools. This tornado was originally rated F6 by Fujita but was later downgraded to F5.

The Fujita scale was adopted in most areas outside of the United Kingdom. [citation needed] On February 1, 2007, the Fujita scale was decommissioned, and the Enhanced Fujita Scale was introduced in the United States. [7] The new scale more accurately matches wind speeds to the severity of damage caused by the tornado. [8]
The Enhanced Fujita scale is used predominantly in North America. Most of Europe, on the other hand, uses the TORRO tornado intensity scale (or T-Scale), which ranks tornado intensity between T0 and T11; F4/EF4 tornadoes are approximately equivalent to T8 to T9 on the T-Scale. Tornadoes rated IF4 on the International Fujita scale are also ...
These scales – the Fujita scale, the Enhanced Fujita scale, the International Fujita scale, and the TORRO tornado intensity scale – attempt to estimate the intensity of a tornado by classifying the damage caused to natural features and man-made structures in the tornado's path. Tornadoes are among the most violent known meteorological ...
The Enhanced Fujita Scale takes into account the quality of construction and standardizes different kinds of structures. The wind speeds on the original scale were deemed by meteorologists and engineers as being too high, and engineering studies indicated that slower winds than initially estimated cause the respective degrees of damage.
