current. Usually the current is caused by the movement of electrons.
cyclone: A system of winds moving in a spiral pattern toward a central low-pressure zone is called a cyclone. Air moves at high speed toward the center of the low pressure. The rotation of the Earth pushes the high-speed winds sideways. The result is a storm with winds spiraling around the center. In the northern hemisphere, the winds blow in a counterclockwise direction. In the southern hemisphere the winds blow in a clockwise direction. Cyclones move across the surface with the wind currents.
