No machine is used. The intensity of a tornado is determined by a visual survey of the damage.
There is no particular instrument used for measuring tornado intensity. Ratings are based primarily on damage assessment. Occasionally doppler radar has measure wind speeds inside a tornado, but such measurements are rare.
The Fujita scale is used to determine how strong a tornado is. It is widely used for two reasons: it was the first scale to assess tornado intensity, and it breaks damage down into six easily recognizable levels.
In some cases, Doppler radar is used to measure winds inside a tornado. However, as these measurements are rare and cannot scan ground-level winds, they are not used in ratings. The intensity rating is determined based on analysis of damage.
The intensity of a tornado is usually judge based on an analysis of the damage, which is used to estimate wind speed.
Tools such as the Enhanced Fujita (EF) scale, drones, satellite imagery, and ground surveys are commonly used to assess and measure tornado damage. These tools help experts determine the intensity and path of the tornado, which in turn helps with emergency response efforts and rebuilding plans.
The Enhanced Fujita Scale (EF Scale) is a commonly used guide for tornado intensity. It categorizes tornadoes based on the damage they cause and estimates wind speeds associated with the damage.
It depends on what substance/object you are trying to determine the intensity.
The intensity of a tornado is primarily determined by the Enhanced Fujita Scale, which takes into account the damage caused by the tornado. Factors such as wind speed, path length, and width of damage are analyzed to assign a rating on the EF Scale, ranging from EF0 to EF5, with EF5 being the most intense.
Ted Fujita discovered the Fujita Scale to determine how much strength a tornado has based on the damage it produces.
In most cases the intensity of a tornado is never actually measured. Tornadoes are rated based on the severity of the damage they cause. Mobile Doppler radar can measure wind speeds in a tornado, but since such radar cannot measure ground-level winds the measurements are not used in ratings.
The Fujita scale is only for tornado intensity. Meteorologists use a different wind scale for hurricanes called the Saffir-Simpson scale.
The Fujita scale uses the damage done by tornadoes to estimate their intensity.
