Wind Systems and Ocean Temperature Distribution
Question
Consider the following statements:
- 1.
In the tropical zone, the western sections of the oceans are warmer than the eastern sections owing to the influence of trade winds.
- 2.
In the temperate zone, westerlies make the eastern sections of oceans warmer than the western sections.
Options
1 only
2 only
Both 1 and 2
Neither 1 nor 2
Explanation
Both statements are correct. In tropical zones, easterly trade winds push warm surface waters westward, making western ocean sections warmer and causing upwelling of cold water along eastern sections. Conversely, in temperate zones, the prevailing westerlies pile up warm surface waters toward the eastern edges of ocean basins, elevating coastal water temperatures along western continental margins. > Planetary wind patterns fundamentally dictate global marine isotherms by transporting warm surface waters across ocean basins. Answer: (c).
