We describe the life cycle of a tornado, its genesis and explain how to recognize a mesocyclonic tornado from a non-mesocyclonic one. Prevention and detection systems such as Doppler radars are also discussed in the report. In a second part, we follow an inertial particle’s trajectory through the velocity field of a Burgers’ vortex model, where gravity, inertia and Stokes drag are applied. Thanks to the equations of motion’s adimensionnalization and the introduction of adimensionnal numbers (Stokes, Froude, Reynolds), we analyze the different equilibrium points and scenarios of particle’s motion for defined values of Stokes, Froude and Reynolds
