The planet rotates around the sun. During the winter (at each pole) the sun is unable to reach the ozone layer just past the pole. Ozone requires this energy too maintain it's existence. Because this energy is not present, ozone will decay into oxygen. Similar issues cause ozone levels in cities lowers at night. When the polar winter is over, the hole disappears quickly. There are two holes, one near each pole and they last in total about twice as long as the winter at each pole.
