Tornadoes take on a spiral shape because the winds in them spin and move upward. This is because tornadoes originate from the rotating updraft of a supercell thunderstorm. The updraft gets this rotation from wind shear.

Why tornado is spiral in shape why do cyclones not have a spiral shape?
The opposite is true. Cyclones ave a spiral shape while tornadoes generally do not. In both a tornado and a cyclone, air spirals in toward a center of low pressure. A cyclone, however, is many times larger than a tornado. Therefore, variations in moisture and air temperature a few miles to a few hundred miles across can be contained within it. These variations give rise to variations in cloud cover, which get twisted into a spiral shape. Tornadoes, which rarely exceed a mile in diameter, are too small to contain such large-scale variations.
