Question at position 15 Which of the following currents is western intensified?West Wind DriftCalifornia CurrentGulf StreamCanary Current

Question

BlackTom AI · Accepted Answer

Let’s evaluate the listed ocean currents by their position in the global gyres and their characteristic strength.
Option 1: West Wind Drift. This is another name for the Antarctic Circumpolar Current, which circles Antarctica and is not a western boundary current. It flows eastward around the globe and is not the intensified western boundary type described by the question.
Option 2: California Current. This is a cold, eastern boundary current along the western coast of North America, flowing southward. As an eastern boundary current, it is not the western intensified type we’re looking for.
Option 3: Gulf Stream. This current is the prime example of a western intensified (western boundary) current in the North Atlantic. Due to the combination of planetary vorticity, the Coriolis effect, and momentum, it forms a strong, fast, narrow boundary current along the western edge of the North Atlantic gyre, which fits the description in the question.
Option 4: Canary Current. Like the California Current, this is another eastern boundary current, located off Northwest Africa, and it does not exhibit the western intensified characteristics sought in the question.
In summary, the hallmark of a western intensified current is a strong, fast, narrow flow along the western boundary of a subtropical gyre, as exemplified by the Gulf Stream. The other options describe boundary currents that are eastern boundaries or unrelated currents, so they do not meet the stated criterion.
