Yes. The intensity of a tornado is estimated on the Enhanced Fujita scale. On this scale, engineers and meteorologists analyze damage and estimate the wind speed. The highest wind speed estimate is then used to assign a rating, ranging from EF0 for the weakest tornadoes to EF5 for the strongest.
yes
No, there is not
There is no way of knowing when the next tornado will be.
If a tornado passes near or over a barometer, it will measure a very rapid drop in pressure. How much the pressure drops depends on the strength of the tornado and how close the center of it comes tot he barometer.
The Fujita and Enhanced Fujita scales assesses damage caused by a tornado to assign a rating.
The are various instruments that scientists have deployed. Most tornado probes carry barometers to measure the pressure inside a tornado. Some have held a variety of anemometers to measure wind speed. A few have had cameras.
There is no such thing as an ice tornado.There is no way of stopping a tornado.
No, it is possible to measure the strength of a tornado, though direct measurements are rare. Most tornadoes have their strength estimated based on the severity of the damage they cause. Occasionally, though mobile Doppler can obtain wind measurements from a tornado. One tornado on May 24, 2011 was rated EF5 after such a radar indicated winds in excess of 210 mph.
The intensity of a tornado is usually judge based on an analysis of the damage, which is used to estimate wind speed.
There is no way of knowing when the next tornado will be in any given place.
