- Dynamic or Thermal Relationship to Thermal Low
- Why is the subpolar low in the Northern Hemisphere discontinuous while the one in the Southern Hemisphere is not?
- What is the triggering mechanism for ENSO?
- Why are the westerlies a less extensive wind system in comparison to the trade winds?
- Dynamic or Thermal Relationship to Thermal High
- a The globe is much smaller at the latitudes that encompass the westerlies.
- b Cold Surface Conditions
- c Warm Surface Conditions
- d The mechanism is rather complex and not well understood at this point.
- e The low-pressure zone in the Northern Hemisphere is interrupted by the greater amount of landmass.
5 Multiple Choice Questions
- It causes air to move at a diagonal to the isolines on a barometric map; it only affects atmospheric movement below 1000 meters; and, it only causes cyclonic and anticyclonic air circulation to move in a "pinwheel"-like fashion near the surface.
- The displacement is greatest in the low latitudes and least near the poles.
- General west-to-east flow; variable wind speeds; meandering ribbon of air.
- Ascending Air
- When the winds encounter a physical barrier (like a mountain).
5 True/False Questions
Santa Ana Winds → Cold, dense air draining off of a plateau via the force of gravity.
As the pressure of a gas increases, the density ___________ and the temperature ______________. → Increases; increases
What best describes a cyclone? → Upper atmosphere convergence, descending air, surface divergence.
In regard to the Coriolis effect, which statement is not correct? Deflection only affects objects that are moving in a north-south or south-north direction; it is weaker near the Equator and stronger closer to the poles; the higher the velocity of an object's movement, the greater the deflection is; or, objects are deflected to the right of their path in the Northern Hemisphere and to the left of their path in the Southern Hemisphere? → Because temperature contrasts in the associated air streams are smaller than that in the midlatitudes.
What are teleconnections? → Upper atmosphere convergence, descending air, surface divergence.
