WebWinds come in all directions and speeds. They are measured by their directions and speeds. Depending on the cause of the winds, they can blow in many directions. Some … WebWinds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Because of Earth’s spin and the Coriolis effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator.
