ackground - Now that you have been introduced to global circulation cells through animation (attached as a file to this assignment) and your instructor'sFig_5_2_wwm, you can begin to use these circulation cells to explain surface wind flow on Earth. You can also use them to begin to understand why Earth's climatic zones are positioned where they are. A key to this understanding lies in what pressure is present (at sea level) at the zones where the circulation cells meet.
Your Task:
1) Determine what pressure - high or low - exists at sea level at these latitudes:
90 N, 60 N, 30 N, 0 , 30 S, 60 S, and 90 S.
2) Describe where the horse latitudes are, what the pressure and wind conditions are there, and why they have this strange name.
For full credit, you must show your work and/or explain your thinking.
Explanation / Answer
1) Since the equator is warmer than poles and warm air has less pressure, the pressure at the equator is less. But at the poles, the cooler air forms higher pressure.
Equatorial low at 0, Sub polar low 60N&60S, subtropical high 30N&30S, polar high 90N&90S
2) Horse latitudes are subtropical 30N and 30S.
Condition is: high pressure and no winds. Dry, clear, fair weather.
When spanish sailing vessels transported horses to the US and the West Indies, when they reached the place their ships would become becalmed and their supplies are over, when they could not afford to water their horses, they used to throw them overboard. Thats why the name came.
