What is the rating scale for tornadoes?

Answer 1

Tornadoes are rated from F0 to F5 on the Fuijta scale (EF0 to EF5 as of 2007 in the U.S.). These ratings are based on damage.

F0, light damage: minor roof damage, gutters knocked down, tree limbs broken, shallow rooted trees toppled.

F1, moderate damage: roofs of frame homes badly stripped of material, trailers severely damage and overturned, windows broken.

F2, significant damage: Roofs torn from frame houses, mobile homes completely destroyed, cars lifted.

F3, severe damage: roofs and walls torn from well built houses, cars thrown, most trees uprooted.

F4, devastating damage: well built houses leveled, trees stripped of bark, poorly anchored buildings moved off foundations.

F5, incredible damage: well built houses swept away, foundations wiped clean.

Answer 2

If you mean its rating on the Fujita (F) scale or Enhanced Fujita (EF) scale, these rating refer to the intensity of the tornado. The Fujita Scale was used to rate tornadoes in the United States based on damage from F0 (weakest) to F5 (strongest). This scale was replaced in 2007 by the enhanced Fujita scale, which uses damage-derived wind speed estimates to rate tornadoes from EF0 to EF5. An EF0 tornado has estimated winds of 65-85 mph and causes "minor" damage such as peeling shingles, breaking tree limbs and uprooting some trees. An EF1 tornado has estimated winds of 86-110 mph and causes "moderate" damage such as badly damaged roofs, broken windows, and overturned trailers. An EF2 tornado has estimated winds of 111-135 mph and causes "significant" damage such as tearing roofs from houses, snapping large trees, and demolishing trailer homes. An EF3 tornado has estimated winds of 136-165 mph and causes "severe" damage such as collapsing walls of most houses, lifting trees, and leveling weak structures. An EF4 tornado has estimated winds of 166-200 mph and causes devastating damage such as the complete leveling of well built houses, the debarking of trees, and stripping asphalt from roads. An EF5 tornado has estimated winds over 200 mph and causes total devastation, wiping well built houses clean off their foundations, and leaving virtually nothing intact.

Most like you are referring to the six levels on the Fujita scale, now the Enhanced Fujita scale in the U.S. These are not so much different kinds of tornado as they are levels of intensity. The categories are listed below, along with estimated wind ranges and typical damage.

EF0: 65-85 mph, light damage. Shingles and siding peeled from houses. Tree limbs broken with some weak trees toppled.

EF1: 86-110 mph, moderate damage. House roofs severely damaged, windows broken. Mobile homes overturned and/or partially destroyed.

EF2: 111-135 mph, significant damage. Roofs torn from well-built homes. Mobile homes completely destroyed. Large trees snapped.

EF3: 136-165 mph, severe damage. most exterior and possibly some interior walls collapsed in well built homes. Most trees uprooted.

EF4: 166-200 mph, devastating damage. Well-built houses completely leveled. Trees debarked. Large objects become projectiles.

EF5: over 200 mph, incredible damage. Well-built houses wiped clean off foundations. Reinforced concrete structures severely damaged. Asphalt torn from roads.

Answer 4

There are not six distinct types of tornado, however, there are six intensity levels. In the United States and Canada, tornadoes are rated on the Enhanced Fujita scale, which is used to rate tornadoes based on the severity of the damage they cause. ratings run from EF0 to EF5. Some other countries use the similar, but older Fujita scale (F0 to F5). Ratings on these two scales are essentially equivalent, though the Enhanced scale is more in-depth and has different wind-speed estimates for a given damage level.

Here are the ratings with estimated wind speeds and typical damage.

• EF0 (65-85 mph): Shingles and siding peeled from some structures. Signs damaged. Tree limbs broken and some weak trees toppled. Very weak, light structures may collapse.
• EF1 (86-110 mph): Roofs of houses severely damaged. Poorly secured roofs may be removed. Some barns and outbuildings collapse. Windows are broken.
• EF2 (111-135 mph): Roofs are torn from well-built houses, but most walls remain standing. Trailer homes and barns are completely demolished. Large trees are snapped. Small cars lifted off the ground.
• EF3 (136-165 mph): Roofs and walls are torn from well-built houses. Weaker structures are completely destroyed. Extensive deforestation may occur.
• EF4 (166-200 mph): Well-built houses are completely leveled. Less well-built houses may be blown away. Trees are stripped of bark. Asphalt may be peeled from some roads.
• EF5 (over 200 mph): Well-built houses are wiped clean off their foundations. Steel reinforced masonry buildings are destroyed. Severe ground scouring may occur.

Answer 5

Tornadoes do not get names as hurricanes do. Instead they are usually referred to by the places they hit. For example, the tornado that devastated Joplin, Missouri in 2011 is known as the Joplin tornado.

Answer 6

The different ratings of tornadoes are F0, F1, F2, F3, F4, & F5 on the Fujita scale. One the EF Enhanced Fujita scale tornadoes, are rated - EF0, EF1, EF2, EF3, EF4, & EF5.

Answer 7

Tornadoes are rated on the Enhanced Fujita Scale. It runs from EF0 at the weakest to EF5 at the strongest. Tornadoes are assigned a rating based on wind speed estimates derived from damage.
