Air sinks at around 30°, forming high-pressure systems and deserts over land. Air then either returns to the equator or moves further northward. Within North American latitudes, the Ferrel cell slowly pushes air upward, forming low-pressure systems, many of which are named after their place of origin, such as the Alberta Clipper and Colorado low. At the North Pole, air subsides within the Polar cell, with the Yukon or Siberian high-pressure systems dominating.
