Current Global Wind 12-12-2014 morning session. Description: The Global Current Wind image shows current wind in kilometers per hour around the world, color contoured every 5 knots. Actual winds are given at selected cities. Wind direction is determined by the direction from which it originates. For example, a northerly wind blows from the north to the south. Wind is the flow of air that occurs as it is heated by the sun and thus rises. Cool air then occupies the area from which the hot air has moved, creating what could loosely be termed a convection current. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the geographic regions in which they occur, or their effect.
