Tornadoes swirl because the storms that produce them rotate. Vertical wind shear is a condition in which there is a difference in wind speed and direction at different altitudes. If there is the right setup of wind shear, it can create horizontally rolling air currents. These currents can then be turned vertical by a thunderstorm updraft, inducing rotation within the storm. Under the right conditions, a portion of this rotation can tighten and intensify, producing a tornado.
