areas) they are called extratropical cyclones or hurricanes, in the western Pacific they are

These complex cells are in the mid-latitudes of both the hemispheres. Some air descending in these
latitudes moves poleward around the 30 latitude mark. It then joins the air from the air returning from
the north at high altitudes. These atmospheric cells are called Ferrel cells. Information can be found in
the section The Atmosphere Moves in Response to Uneven Solar Heating and Earth's Rotation.
