The most well-known current is the Gulf Stream current. The Gulf Stream flows from the Gulf of Mexico, p Florida and cuba and makes its way across the Atlantic ocean to Europe. It is 100 200 kilometers wide. As the Gulf Stream flows into the North Atlantic Ocean, cools and evaporates. Due it to temperature changes between the water and air, cyclones or hurricanes form. Since the Gulf Stream flows more quickly than other currents, ships use it to sail from west to east. The advantage of using the Gulf Stream for sailing was discovered back in the 16th century. Spanish explorers sailing home to Europe followed the Gulf Stream because the currents were very fast.
