Tornadoes can be detected by Doppler radar, but eyewitness reports are important, too.
A tornado's rating is determined by damage, which is used to estimate the tornado's peak wind speed.
how big are tornadoes
The loudness and sometimes the pitch of the musical instrument.
'Sonar". And determines depth. The ocean floor topography can be mapped by 'sonar scanning'.
A thermometer can measure body Temperature. A bolometer measures heat radiation. A calorimeter determines quantities of heat.

A variable that could influence the accuracy of an instrument is the reference standard that was used to calibrate the instrument.
the answer is you have to use the right instrument on somthing to get the right answer
The presence of silicon and oxygen.
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.
Presence or absence of the Y chromosome
Tornadoes are usually detected using Doppler radar.
A thermometer - body Temperature bolometer - an instrument that measures heat radiation calorimeter - a measuring instrument that determines quantities of heat
a multimeter?
The presence of a Y chromosome.
