The original F or Fujita scale rates tornadoes from F0 to F5 based on the severity of damage and gives each tornado an estimated range of windspeeds based on this.
The EF or Enhanced Fuijta scale examines damage in more detail. Engineers and meteorologists look at the damage and determine the tornado's peak wind speed and use that to get the rating.
For example, if damage indicates a tornado had 120 mph winds at its strongest, it is rated EF2, with winds ranging from 111 to 135 mph
The wind estimates for the categories have been adjusted for the new scale, here is a comparison of the old and new. Keep in mind that even though the wind estimates for each category have changed the damage for those categories remains essentiall the same
F0 40-72 mph EF0 65-85 mph
F1 73-112 mph EF1 86-110 mph
F2 113-157 mph EF2 111-135 mph
F3 158-206 mph EF3 136-165 mph
F4 207-260 mph EF4 166-200 mph
F5 261-318 mph EF5 over 200 mph

What are the different types of tornadoes?
The two main types of tornadoes are supercell tornadoes, which form from rotating thunderstorms, and non-supercell tornadoes, which form from different weather patterns like landspouts or waterspouts. Additionally, tornadoes can be classified based on intensity using the Enhanced Fujita (EF) scale, which ranges from EF0 (weakest) to EF5 (strongest).
What is the difference between a F1 tornado and an EF1 tornado?
There is very little difference. In February of 2007 the Fujita or "F" scale was replaced with the Enhanced Fujita or "EF" scale. The EF scale uses more detailed analysis of damage than the original F scale so that tornadoes can be rated more accurately. The EF scale also provides different estimates of wind speeds for the degrees of damage. So EF1 damage is essentially the same as F1 damage but it may be examined in greater detail. Additionally F1 wind estimates range from 73 mph to 112 mph while EF1 wind estimates range from 86 mph to 110 mph.
May a F-3 tornado blow up a house?
An EF-3 tornado can cause significant damage to a house, including tearing off roof materials and exterior walls. However, the complete destruction of a house would typically require a higher intensity tornado, such as an EF-4 or EF-5.
What are common tornado ratings?
There are six ratings of tornadoes ranging from EF0 at the weakest to EF5 at the strongest. About 90 percent of tornadoes are rated EF0 or EF1. The higher the rating, the less often it occurs. Other countries use similar ratings from F0 to F5, as the U.S. did until 2007. The same principle applies here as well.
136 degrees F difference between -127 degrees F?
To find the difference between -127 degrees Fahrenheit and 136 degrees Fahrenheit, you would subtract -127 from 136. This gives a difference of 263 degrees Fahrenheit.
What is tornado scale called?
Tornadoes are rated on the Enhanced Fujita (EF) scale. It is an upgraded version of the Fujita (F) scale.
What are the key differences between the Canon EF 50mm f/1.8 II and the Canon EF 50mm f/1.8 STM lenses?
The key differences between the Canon EF 50mm f/1.8 II and the Canon EF 50mm f/1.8 STM lenses are in their autofocus systems. The EF 50mm f/1.8 II has a traditional micro motor for autofocus, while the EF 50mm f/1.8 STM has a newer Stepping Motor (STM) for smoother and quieter autofocus performance.
In F or EF rating's of a tornado. what's the E or F mean or stand for?
The F stands for Fujita - the name of the scale used to indicate the strength of tornadoes. The E - stands for enhanced.
What are the different types of tornadoes?
The two main types of tornadoes are supercell tornadoes, which form from rotating thunderstorms, and non-supercell tornadoes, which form from different weather patterns like landspouts or waterspouts. Additionally, tornadoes can be classified based on intensity using the Enhanced Fujita (EF) scale, which ranges from EF0 (weakest) to EF5 (strongest).
What does ef mean with a tornado terms?
EF stands for the Enhanced Fujita scale. it is a scale derived from the Fujita or F scale put into use in the United States in 2007. It rates tornadoes into six categories based on the severity of the damage they inflict. The weakest tornadoes are rated EF0 while the strongest are rated EF5.
What are the best EF-M lenses that are compatible with the EF mount?
The best EF-M lenses compatible with the EF mount are the Canon EF-M 22mm f/2 STM, Canon EF-M 32mm f/1.4 STM, and Canon EF-M 11-22mm f/4-5.6 IS STM.
What are the main differences between the Canon EF 17-55mm f/2.8 and the Canon EF 24-70mm f/2.8 lenses?
The main differences between the Canon EF 17-55mm f/2.8 and the Canon EF 24-70mm f/2.8 lenses are their focal length ranges and sizes. The EF 17-55mm has a wider angle of view, making it better for capturing landscapes and wide shots, while the EF 24-70mm has a longer focal length range, making it more versatile for different types of photography. Additionally, the EF 17-55mm is smaller and lighter, making it more portable, while the EF 24-70mm is larger and heavier.
What are the differences between the Canon EF 70-200mm f/2.8L IS USM and the Canon EF 70-200mm f/2.8L IS II USM lenses?
The main differences between the Canon EF 70-200mm f/2.8L IS USM and the Canon EF 70-200mm f/2.8L IS II USM lenses are improved image stabilization and optical performance in the II version. The II version also has better build quality and weather sealing.
Why was the Fujita scale changed to the EF scale And what exactly does EF stand for?
EF stands for Enhanced Fujita. It was changed from the original Fujita or "F" scale in order to provide more accurate ratings and to correct wind speeds. The original Fujita scale's damage descriptions were too generalized and it overestimated the winds of strong tornadoes.
What is the difference between -13 f and 30 f?
The difference is 43o F
What are the differences between the Canon EF 50mm f/1.8 STM and the Canon EF 50mm f/1.8 II lenses?
The Canon EF 50mm f/1.8 STM lens has a newer design with smoother and quieter autofocus, while the Canon EF 50mm f/1.8 II lens has an older autofocus system that is noisier. The STM lens also has better image quality and build quality compared to the II lens.
What are the differences between the Canon EF 70-200mm f/2.8L IS lens and the non-IS version?
The main difference between the Canon EF 70-200mm f/2.8L IS lens and the non-IS version is the presence of image stabilization (IS) in the IS version. Image stabilization helps reduce camera shake and allows for sharper images when shooting handheld at slower shutter speeds. The IS version is typically more expensive and heavier than the non-IS version.
