The Coriolis Effect
deflection of a moving object, caused by the
moving frame of reference on the spinning
Earth. How does this apply to the
atmosphere? As air warms, expands, and rises at
the equator, it moves toward the pole, but
instead of traveling in a straight path, the air
is deflected eastward. In the N. Hemisphere air
turns to the right. In the S. Hemisphere air
turns to the left.

Atmospheric Circulation Cells
Large circuits of air are called an atmospheric
circulation cells. Three cells exist in each
hemisphere. They Are Hadley cells are tropical
cells found on each side of the equator. Ferrel
cells are found at the mid-latitudes. Polar
cells are found near the poles.

Wind Patterns
Cell Circulation Drives Wind Patterns The
doldrums are calm equatorial areas where two
Hadley cells converge. The horse latitudes are
areas between Hadley and Ferrel cells. There is
little surface wind in this area. The trade
winds are surface winds of Hadley cells. The
westerlies are surface winds of Ferrel cells.

Differential Heating
Monsoons are seasonal patterns of wind
circulation. Characterized by dry winters and wet
summers. Sea breeze is cool air from over the
water moving toward land. Sea breezes occur after
sunrise. Land breezes occur after sunset when
air cooled by the land blows toward the water.

Effect of Air Movement on Water

• Friction between moving air and water causes
  WAVES
• Ocean Currents are caused by the prevailing
  winds, and tend to show circular patterns due to
  Coriolis affect spin clockwise in N. Hemisphere,
  counterclockwise in S. Hemisphere
