Question

Is gravity effect to the air

Answer 1

One of the forces acting on a parcel of air is gravity. It pulls the air downwards and produces a density distribution in such a way that heavier air is below the lighter air. In a high pressure area, cold and heavy air sinks from a higher level and continues its journey as a horizontal wind(which we usually refer to as wind) towards a low pressure area where it rises and completes the wind circulation (like Hadley cell).So, gravity affects the wind also to some extent.
