1. Do you understand the relationship between air pressure and wind?
2. Can you identify the various forces that affect the magnitude and direction of the wind?
3. Can you explain the rotation of large-scale weather systems?
4. Do you understand the relationship between station pressure
and sea level corrected pressure?
1. Why does air pressure decrease with height more rapidly when the air is cold?
2. What force initially sets air in motion?
3. Would you expect to observe a geostropic wind above the equator? Why or why not?
4. If the clouds above you are moving north to south, is the center of a low pressure system with respect to where you are standing east or west of your position?
5. Why are surface winds that blow over the ocean closer to being geostropic than those that blow over the land?
6. A station 300 meters above sea level reports a station pressure of 994 millibars. What would be the sea level correction for this station assuming standard conditions. Would the reading be greater or less if the observation were made on a hot summer day?
7. Explain how the wind aloft can be very strong when the PGF
and the Coriolis force balance each other out.
