The climate of the Atlantic Ocean and adjacent land areas is influenced by the temperatures of the surface waters and water currents as well as the winds blowing across the waters. Because of the ocean’s great capacity for retaining heat, maritime climates are more moderate and have fewer tendencies toward extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from the water temperatures. The oceans are the major source of the atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest climatic zones stretch across the Atlantic north of the equator. The coldest zones are in the high latitudes, with the coldest regions corresponding to the areas covered by sea ice. Ocean currents contribute to climatic control by transporting warm and cold waters to other regions. Adjacent land areas are affected by the winds that are cooled or warmed when blowing over these currents. The Gulf Stream and its northern extension towards Europe, the North Atlantic Drift, for example, warms the atmosphere of the British Isles and north-western Europe, and the cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks area) and the north-western coast of Africa. In general, winds tend to transport moisture and warm or cool air over land areas.
Atlantic Ocean History
• In 1858, the first transatlantic telegraph cable was laid by Cyrus Field.
• In 1919, the American NC-4 became the first airplane to cross the Atlantic (though it made a couple of landings on islands along the way).
• Later in 1919, a British airplane piloted by Alcock and Brown made the first non-stop transatlantic flight from Newfoundland to Ireland.
• In 1921, the British were the first to cross the North Atlantic in an airship.
• In 1922, the Portuguese were the first to cross the South Atlantic in an airship.
• The first transatlantic telephone call was made on January 7, 1927.
• In 1927, Charles Lindbergh made the first solo non-stop transatlantic flight in an airplane (between New York City and Paris).
• After rowing for 81 days and 2,962 miles, on December 3, 1999, Tori Murden became the first woman to cross the Atlantic Ocean by rowboat alone when she reached Guadeloupe from the Canary Islands.
