What describes the movement of wind?
What describes the movement of wind? Movement of air caused by temperature or pressure differences is wind. Consequently, air blows anticlockwise around a low pressure centre (depression) and clockwise around a high pressure centre (anticyclone) in the northern hemisphere (see Figure 3.1). Which set of conditions describes a low pressure system? Explanation: A low pressure […]
