When an area of low pressure is created with strong winds that spiral towards the center, a tropical cyclone is being formed. The spiral arrangement of thunderstorms produces heavy rain.

In zones where air ascends, the air is less dense than its surroundings and this creates a center of low pressure. Winds blow from areas of high pressure to areas of low pressure, and so the surface winds would tend to blow toward a low pressure center. In zones where air descends back to the surface, the air is more dense than its surroundings and this creates a center of high atmospheric pressure. Since winds blow from areas ofhigh pressureto areas oflow pressure, winds spiral outward away from the high pressure. The Coriolis Effect deflects air toward the right in the northern hemisphere and creates a general clockwise rotation around the high pressure center. In the southern hemisphere the effect is just the opposite, and winds circulate in a counterclockwise rotation about the high pressure center. Such winds circulating around a high pressure center are calledanticyclonic windsand around a low pressure area they are calledcyclonic winds.

Winds actually move from areas with higher pressure levels to areas with lower pressure levels, horizontally. Winds actually move from areas with higher pressure levels to areas with lower pressure levels, horizontally.
Winds in a tornado spiral inward and upward.
In the Northern Hemisphere winds spiral to the right; while in the southern hemisphere winds spiral to the left.
Tornadoes generally don't have a spiral shape. But the winds in and near a tornado always move in a spiral pattern.

anticlones
A tornado does not have a spiral shape or appearance (except in some cases where helical subvortices form), but the winds in and near a tornado move in a spiral fashion.

Winds move toward the center of a hurricane because of the low pressure generated by the upward motion of the air inside it.
