▪ air current
      persistent wind that blows westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone (ITCZ). It is stronger and more consistent over the oceans than over land and often produces partly cloudy sky conditions, characterized by shallow cumulus clouds, or clear skies that make trade-wind islands popular tourist resorts. Its average speed is about 5 to 6 metres per second (11 to 13 miles per hour) but can increase to speeds of 13 metres per second (30 miles per hour) or more. The trade winds were named by the crews of sailing ships that depended on the winds during westward ocean crossings.
