Which major ocean current is a warm, swift western boundary current of the North Atlantic subtropical gyre that significantly moderates the climate of northwestern Europe?

💡 Solution & Explanation

The Gulf Stream is a powerful warm western boundary current originating in the Gulf of Mexico, flowing up the eastern coast of North America before crossing the Atlantic towards Europe as the North Atlantic Drift. The California and Canary currents are cold eastern boundary currents flowing equatorward along continental margins. Ocean current systems play a dominant role in heat energy transport across latitude zones.
