Consider the following statements regarding the global distribution of major ocean gyres: 1. Subtropical ocean gyres rotate in a clockwise direction in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere. 2. The western boundary currents of these gyres are typically narrower, deeper, and faster than their eastern boundary counterparts. Which of the statements given above is/are correct?

💡 Solution & Explanation

Both statements accurately describe ocean gyre dynamics. Coriolis deflection causes subtropical gyres to circulate clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere. Western boundary currents such as the Gulf Stream and Kuroshio Current are intensified due to the Earth's rotation gradient, making them swift and deep compared to broader, slower eastern boundary currents like the California or Canary currents. Western intensification is a fundamental principle of physical oceanography.
