Question
1) Select the three forces that have the largest impact on the direction of the wind.
2) In which region are you likely to experience the most seasonal climate variability?
3) Which of the following statements is false?
4) Within an Ekman spiral in the Northern Hemisphere, which of the following is true?
5) Which of the following is not one of the main drivers for surface ocean currents?
6) Select all statements that correctly describe ocean gyres.
7) Which of the following correctly describes El Nino?
8) Upwelling leads to nutrients at the surface of the Ocean and in some cases, an increase in the fish population. Knowing this, when would be the best time to fish in the eastern Pacific Ocean?
9) When is Australia more likely to experience a drought?
10) Why did you answer the previous question as El Nino or La Nina?
a) GravityExplanation / Answer
1)
Coriolis, Pressure gradient force and Friction
2)
In the Falkland Islands off the southern coast of Argentina
3)
Precipitation is enhanced wherever circulation promotes subsidence
4)
In the ocean under a wind-induced surface stress, the direction of currents turns clockwise and the speed decreases with depth. The resulting effect is a net movement of water at an angle of 90 to the left of the wind direction.
5)
Ocean Instability
6)
Transport heat poleward, Circulate clockwise in the northern hemisphere and counterclockwise in the southern hemisphere
7)
During El Nino, the Pacific Ocean becomes unusually warm, the easterly trade winds strengthen, resulting in more upwelling in the eastern Pacific.
8)
During La Nina
9)
During El Nino
10)
During ENSO years convective, low pressure regions shift towards Australia and away from the central pacific.Related Questions
