Energy of the Ocean: The Coriolis Effect
Hello! Today we watched a video about The Coriolis Effect. Afterwards, we have to go on a website and answer questions. Here is the website below. I'll see you later. Peace!

The Coriolis Effect Defined: What in the World is it?- Warm Air Rises and Cold Air Falls- Why?
What is the general pattern of wind currents on the globe?
>The general pattern of wind currents on the globe is that surface temperatures are higher at the equator (than the poles). Air heats in the tropics, expands, becomes less dense, and then rises to the poles. In the poles the air cools, contracts by spreading into space, sinks to the surface, and comes back to the tropics.
What is a convection current?
>A convention current is when air flows around an area and back to the source. The warm air becomes less dense and rises, whereas the cold air becomes denser and falls.
Global circulation is driven by which two processes?
>Global circulation is driven by uneven solar heating and the rotation of the earth.
Notes:
Density - Temperature and water vapor have a great influence air density. Humid air is less dense than cold air.
Pressure - Near the Earth's surface, air molecules are packed tightly together. As they rise, they become less dense, expands, and becomes cool. Cooler air masses hold less water than warm air. As they fall, they become compressed and heat up.
Putting it all Together- Define and Explain:
Hadley Cells - This is when air rises at the equator, loses moisture by rainfall caused by expanding and cooling. When it has traveled 30 degrees north and 30 degrees south in latitude, the air becomes dense enough so it falls to the surface. The Coriolis Effect deflects this surface air to the right, with the air blowing across the surface creating the Easterly trades.
Ferrel Cells - These mid-circulation cells form a loop between 30 and 50-60 degree latitude. Air is driven by uneven heating and persuaded by the Coriolis Effect. The surface wind is deflected to the right forming the Westerly Winds.
Polar Cells - Air that is cold at the poles that is being blown towards the equator at the surface and turns to the west. When each hemisphere is between 50-60 degrees latitude, and then it has taken enough heat and moisture to ascend. Then the air turns to poleward to a complete full circuit called the Polar Cells.
Horse Latitudes - This area of high atmospheric pressure with little surface wind (the subtropical high). Which are some dry bands centered around the 30 degree mark Hadley and Ferrel cells as intersection mark.
Doldrums - A special term created by the sailors for the calm equatorial areas where two Hadley surface winds converge.
