The strongest and most damaging tornadoes from within supercells. This is one of the primary reasons why researchers strive to understand them better. They want to be able to predict them (e.g. left figure) more accurately.

Computer models can now produce the general behavior of tornadoes like the one above on the right. Weightless tracer particles are used to define the tornado's flow. However, determining which supercells will produce tornadoes remains a challenging task that is still under investigation.
