A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Historically, wind roses were predecessors of the compass rose, as there was no differentiation between a cardinal direction and the wind which blew from such a direction.
Wind is described by its direction and speed. Wind direction is the direction from which the wind blows. It is usually expressed in terms of the point of compass. Air moving from east to west is called easterly wind. Wind speed is the speed of the air flow.ind direction is the direction from which the wind blows.
