That is what this web site intends to explain. Local winds affect us everyday and have led to mass destruction of different places around the world. There are various types of winds that contribute to this. But first one needs to have the understanding of what wind is.
Wind is the air flowing horizontally with respect to the earth's surface.
Air flows from areas of high pressure to areas of low pressure. The unequal heating of the Earth's surface creates these pressure differences. In order to balance them nature uses wind. However, air cannot always flow directly from high to low pressure because the Earth rotates and there is friction. The Coriolis Effect Friction Pressure-Gradient Force Wind is generated by horizontal pressure differences.
