European exploration
Map depicting the European exploration of the New World in the 15th and 16th centuries, including the voyages made by Christopher Columbus, John Cabot, Alonso de Ojeda and Amerigo Vespucci, Pedro Álvares Cabral, Ferdinand Magellan and Juan Sebastián del Cano, Giovanni da Verrazzano, Jacques Cartier, Sir Francis Drake, and others. The lines of demarcation represent an early division between the territory of Spain (to the west) and Portugal (to the east).
Christopher Columbus utilized the natural clockwise circulation patterns of the North Atlantic to navigate his return to Europe. While he relied on the northeast trade winds to facilitate his westward crossing to the Caribbean, he utilized the Atlantic westerlies for his return journey.12
These prevailing westerly winds, combined with the influence of the Gulf Stream and the North Atlantic Current, provided the necessary conditions to carry his ships back toward the European coast. This successful return demonstrated that ships could navigate the Atlantic by taking advantage of these prevailing wind and current systems, a practice that became a foundational pattern for subsequent European exploration and colonization of the Americas.1342
