How are tornadoes classified?
Here is the Fujita (F) Scale:F-0 40-72 mph, Light damage, chimney damage, tree branches brokenF-1 73-112 mph, Moderate damage, mobile homes pushed off foundation or flipped overF-2 113-157 mph, Considerable damage, mobile homes demolished, trees uprootedF-3 158-205 mph, Severe damage, roofs and walls torn down, trains overturned, cars thrown aroundF-4 207-260 mph, Devastating damage, well-constructed walls leveledF-5 261-318 mph, Violent damage, homes lifted off foundation and carried considerable distances, autos thrown as far as 100 meters.
How big is an F0 tornado?
There is no particular size, as tornado ratings are based on the severity of the damage caused, not the size of the tornado. That said, F0 tornadoes are typically small. Most are less than 100 yards wide.
Why does the size of a tornado not determine the damage of a tornado?
The damage severity in a tornado is determined primarily by wind speed. For example, a tornado with peak winds of 100 mph, even if it is very large, is not going to obliterate well built houses, thought it will cause severe roof damage. By contrast, even a relatively small tornado with peak winds of 250 mph can completely destroy just about any structure.
How high can the wind speed go for an elephant trunk tornado?
Contrary to popular belief, the size and shape of a tornado is not a very good indicator of intensity. In 1995 an elephant trunk tornado struck the outskirts of Pampa, Texas. Using video analysis, tornado expert Thomas Grazulis estimated the wind speed to be approximately 300 miles per hour (480 km/h).
On celsius scale water boils at what temperature?
100 degrees (at sea level).
Is there a f6 on the fujita scale?
actually there is an F6 on the fujita scale but there arent any recorded. It would be impossible to tell whether or not it is an F6. Look at this list.The Fujita ScaleFrom this websitehttp://www.tornadoproject.com/fscale/fscale.htmF-Scale Number Intensity Phrase Wind Speed Type of Damage Done F0 Gale tornado 40-72 mph Some damage to chimneys; breaks branches off trees; pushes over shallow-rooted trees; damages sign boards. F1 Moderate tornado 73-112 mph The lower limit is the beginning of hurricane wind speed; peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos pushed off the roads; attached garages may be destroyed. F2 Significant tornado 113-157 mph Considerable damage. Roofs torn off frame houses; mobile homes demolished; boxcars pushed over; large trees snapped or uprooted; light object missiles generated. F3 Severe tornado 158-206 mph Roof and some walls torn off well constructed houses; trains overturned; most trees in fores uprooted F4 Devastating tornado 207-260 mph Well-constructed houses leveled; structures with weak foundations blown off some distance; cars thrown and large missiles generated. F5 Incredible tornado 261-318 mph Strong frame houses lifted off foundations and carried considerable distances to disintegrate; automobile sized missiles fly through the air in excess of 100 meters; trees debarked; steel re-inforced concrete structures badly damaged. F6 Inconceivable tornado 319-379 mph These winds are very unlikely. The small area of damage they might produce would probably not be recognizable along with the mess produced by F4 and F5 wind that would surround the F6 winds. Missiles, such as cars and refrigerators would do serious secondary damage that could not be directly identified as F6 damage. If this level is ever achieved, evidence for it might only be found in some manner of ground swirl pattern, for it may never be identifiable through engineering studies
Why Celsius scale is also called centigrade scale?
The Celsius scale is also known as the centigrade scale because it is divided into 100 equal intervals (centi- meaning 100). This scale was originally developed with 0 representing the freezing point of water and 100 representing the boiling point of water at sea level.
Water boils at a temperature of what degrees on the Celsius scale?
The Celsius scale is in fact based on water, it freezes at 0 degrees and boils at 100 degrees Celsius at 760 mm Hg pressure.
What is a tornado rated at with winds of 100 mph?
A tornado with estimated winds of 100 mph would be rated EF1.
What is the greatest wind speed of a F1 hurricane?
There is no such thing as an F1 hurricane. F1 is a rating on the Fujita scale, which is used for tornadoes, not hurricanes. Hurricanes are rated on the Saffir-Simpson scale, which ranges from category 1 to category 5. The maximum wind speed for an F1 tornado is 112 mph (180 km/h). The maximum wind speed for a category 1 hurricane is 95 mph (153 km/h).
How big is a typical tornado?
A typical tornado is about 50 to 100 yards wide.
Which temperature scale measures water boiling at 100 degrees?
Fahrenheit: 212 °F is the boiling point of water.Celsius: 100 °C is the boiling point of water.But, as water (at sea level) begins to boil at the temperatures shown above, the scale used is only relevant to which scale we want to use at the time!When the two scales are shown side by side for comparison, the boiling point is shown at the same level.
