    "abstract": "We connect an appropriate feedback loop to a model of 2D vertical eddy of\nairflow which unfolds a wide range of vorticity behavior. Computational fluid\ndynamics of the twisted roll display a class of long lifespan 3D vortices. On\nthe one hand, the infinitely stable columnar vortex simulated describes\nwaterspouts and tornadoes with extended lifetime. On the other hand, a light\nmodification of the retroaction exhibits strong similarities to tropical\ncyclones. Moreover, we investigate the outcome of the twisting process\nvertically shifted. This modelisation leads to the simulation of simultaneous\nvortices associated to this other class of 3D vortices with short lifespan. Our\nheuristic dynamical systems lay the foundations of a comprehensive modelisation\nof vortices since it joins theory and numerical simulations.",
