What is wind anyway?

Wind is air in natural motion as that moving horizontally at any velocity along the earth's surface; It can also be defined as a storm, or a stream of air. Wind blows from areas of high to low pressure. The pressure gradient and the Corriolis effect determine which direction the winds blows. The pressure gradient is the force of air moving from high to low. It is greater if the difference in air pressure is greater. The corriolis effect is an apparent force due to the earths rotation. It causes wind in the northern hemisphere to be deflected to the right. The stronger the winds the stronger the deflection will be.
