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 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]
This work has led to the creation of the Fujita scale (F-scale) in 1971 and the TORRO scale in 1975. However, the original Fujita scale lacked the incorporation of diverse empirical damage to estimate wind speeds, such as construction quality; to address this, the Enhanced Fujita scale (EF-scale) was created in 2007, followed by the ...
In 2018, the International Fujita scale was created by the European Severe Storms Laboratory as well as other various European meteorological agencies. Unlike the other three scales (Fujita, Enhanced Fujita, and TORRO), the International Fujita scale has overlapping wind speeds within the ratings.
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 ...
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.

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. [note 1] [note 2]
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 ...
