Tornadoes don't "know" anything. They are not alive and cannot think or feel.
They are a physical phenomenon governed by thermodynamics and fluid dynamics. Certain atmospheric conditions including instability, the presence of a front or other storm system, and strong wind shear create an environment in which tornadoes are likely.

Tornadoes come in all seasons but are most common in spring and summer.

Tornadoes come from the energy released in a thunderstorm. As powerful as they are, tornadoes account for only a tiny fraction of the energy in a thunderstorm.
Tornadoes are not named. There are too many of them for any sort of naming system.
