ferrel synonyms, ferrel pronunciation, ferrel translation, English dictionary definition of ferrel. In this cell the surface wind would flow from a southerly direction in the northern hemisphere. The mid-latitude circulation cell is the Ferrel cell. ferrule top to bottom: household paintbrush, round paintbrush, and cosmetic brush n. 1. Define ferrel. The Ferrel cell has opposite motion to the other two cells because it is equalizing the uneven temperatures between the equator and the poles. Local or regional atmospheric disturbance characterized by strong winds often accompanied by precipitation. Ferrel cell - A mid-latitude atmospheric circulation cell for weather named by Ferrel in the 19th century. The Ferrel cell is the average motion of air in the mid-latitudes.occurs at higher latitudes (between 30 degrees and 60 degrees N and 30 degrees and 60 degrees S. In the Ferrel cell, air flows poleward and eastward near the surface and equatorward and westward at higher altitudes; this movement is the reverse of the airflow in the Hadley cell . The Ferrel cell moves in the opposite direction to the two other cells (Hadley cell and Polar cell) and acts rather like a gear. Boundary between the polar cell and the Ferrel cell in each hemisphere. Together, the Hadley, Ferrel, and polar cells comprise the three-cell model shown in the diagram. The Ferrel cell moves in the opposite direction to the two other cells (Hadley cell and Polar cell) and acts rather like a gear. Thermally Direct Cells (Hadley and Polar Cells) Both cells have their rising branches over warm temperature zones and sinking braches over the cold temperature zone. Liquid or solid water that falls from the air and reaches the surface as rain, hail, or snowfall. See more. The Ferrel cells are indirect cells, driven by the direct cells to the north and south of them. Both cells directly convert thermal energy to kinetic energy. The Ferrell cell is between 30oN and 50o to 60oN. precipitation. It might be thought of as an eddy created by the Hadley and polar cells. This cell shares its southern, descending side with the Hadley cell to its south. Thermally Indirect Cell (Ferrel Cell) This cell rises over cold temperature zone and sinks over warm temperature zone. The Ferrel cell, theorized by William Ferrel (1817–1891), is, therefore, a secondary circulation feature, whose existence depends upon the Hadley and polar cells on either side of it. In this cell the surface wind would flow from a southerly direction in the northern hemisphere. Once over the poles, the air sinks, forming the polar highs. At the surface, these winds are called westerlies and the cell is known as the Ferrel cell. This type of cell in the tropics is called the Hadley Cell. Polar cell - Air rises, diverges, and travels toward the poles. Between them, these cells transport warm air away from the equator and cool air toward the equator. In the mid-latitudes, the circulation is that of dipping cold air that comes from the poles and the mounting warm air that blows from the subtropical high. Feral definition, existing in a natural state, as animals or plants; not domesticated or cultivated; wild. Its northern rising limb is shared with the Polar cell located between 50 degrees N to 60 degrees N and the North Pole, where cold air descends. storm. In this cell the air flows poleward and eastward near the surface and equatorward and westward at higher levels.
