A tornado's rating is determined by damage, which is used to estimate the tornado's peak wind speed.
The roof load is a rating that determines how many pounds per square foot the roof will withstand. Most roofs are rated above 300 pounds per square foot or more.
Meteorologists use a scale for tornadoes called The Fujita Scale. The Fujita Scale was made by Dr. Ted Fujita. It's the strength of the tornado measured from the damage. The scale goes like this: EF-0: Winds: 65-85mph EF-1: Winds: 85-110mph EF-2: Winds: 111-135mph EF-3: Winds: 136-165mph EF-4: Winds: 166-200mph EF-5: Winds: >200mph EF stands for Enhanced Fujita and the numbers are just categories for the tornadoes (0-5)
No, EF is for Enhanced Fujita scale and F is for Fujita scale. The new scale, implemented in 2007 is more accurate, but ratings are essentially equivalent. Most tornadoes would receive the same rating on either scale.
Tornados cause mass damage. Causing homelessness, injury, and death.
The EF or Enhanced Fujita scale is primarily based on damage. Scientists analyze the damage done by a tornado to estimated what how strong its winds were at peak intensity. The tornado is given the EF rating whose wind range corresponds with the peak wind estimates of the tornado. Because of the uncertainty of these wind estimates direct win measurements are not used even when they are obtained. Here are the wind estimate ranges of the Enhanced Fujita scale levels. EF0: 65-85 mph EF1: 86-110 mph EF2: 111-135 mph EF3: 136-165 mph EF4: 166-200 mph EF5: over 200 mph
EF stands for Enhanced Fujita, which is a scale used to rate the intensity and damage caused by tornadoes. The EF scale ranges from EF0 (weakest) to EF5 (strongest), and takes into account the estimated windspeed and the extent of damage to buildings and vegetation.
Enhanced Fujita
The size of a resistor is a physical characteristic that determines its power rating.
EF stands for Enhanced Fujita, which is the name of the scale. It is adapted from the Fujita scale which was developed by Dr. Tetsuya Fujita in 1971.
The most common rating for a tornado is EF0, accounting for almost 60% of tornadoes in the U.S. The higher the rating, the less often it occurs.
There is no "category" for winds in a tornado. Tornadoes are measured by the Enhanced Fujita Scale, which simply is a rating based on the amount of damage done. It ranges from weakest EF-0, to strongest EF-5....250mph winds are "capable" of producing EF-5 damage, should it move over certain sturdy structures. However, a tornado over an open field with 250mph will not get an EF-5 rating because it has no sturdy structures for it to damage. Tornadoes are rated after the fact based on the amount of damage done. So while a 250mph wind "could" produce EF-5 damage, it's got to move over the right structures for that damage to be realized and the tornado given that rating.
USA has had the most tornados
Pensacola Tornados ended in 1995.
Pensacola Tornados was created in 1983.
The leading rating agencies give a rating when a bond is first issued, and that rating determines how high the interest rate on that bond is. A higher rating means the bond will have a lower interest rate.
Well, it's the weight rating of the trailer which actually determines this. 3000 lbs. weight rating and up, you do.
The highest rating on the Enhanced Fujita (EF) scale is EF5. Tornadoes this strong are extremely rare. Since the the scale was first put into effect in February of 2007 only ten tornadoes have been rated EF5.
