Answer:
Ferrel Cell.
Step-by-step explanation:
Ferrel cell is the circulating air that occurs between 30° and 60° or S of the equator. From 30° latitude to 60° latitude, a new cell is present which is known as the Ferrel Cell. This Ferrel cell produces prevailing westerly winds at the surface on these latitudes. Ferrel cell is a model for the wind circulation of mid-latitude segment of Earth which was proposed by William Ferrel in 1856.
