An unusual six-sided version of this phenomenon can be found at Saturn's North Pole. Chevron patterns on Jupiter within these things indicate the presence of gravity inertia waves. This phenomenon oscillates from a northern to a southern position depending on the modes of the PMA. Undulations within these phenomenon are called Rossby waves, and the southern branch of one of these entities is responsible for "pineapple express" events. During a cold winter, the nocturnal types of these phenomena can form, which partly are responsible for ozone depletion in Antarctica. These phenomena are usually found in the troposphere and generally move from east to west; two examples of them are the polar "ones" within the upper air westerlies, and the subtropical, or mid-latitude ones. For 10 points, name these movements of wind that are found in the upper atmosphere.
