  1. Describe the relationship between wind direction and surface current direction for the following currents in the North Pacific ocean basin:
    1. North Pacific (NP) current
    2. North equatorial (NE) current
    3. Kuroshio (K) current
    4. California (Cal) current
  2. Describe the general pattern or relationship between wind direction and surface current direction. How does this pattern change between the northern and southern hemispheres?
  3. Explain why the five oceanic highs shown in Fig. 3.13 are located in their current position. Explain you answer in terms of their latitudes and circulation cells.
  4. Why are the directions of outflowing wind from high pressure systems different in Earth’s two hemispheres?
  5. Where do you think the low-pressure centers are on Fig. 3.13? Explain your reasoning.
  6. Describe the directions of the currents that flow offshore of the east coast and the west coast of the United States. How do you think these currents affect the climates along these coasts?
  7. If you were to be cast away from a sinking ship in a raft without any paddles off the northwestern coast of Africa, where do you think you would land? List the names of the currents traveled on your voyage (using Fig. 3.14).
  8. How do you think ocean currents affect the paths of hurricanes? Explain your reasoning.
