Aerodynamics is a sub-discipline of fluid dynamics which deals with the movement of air around a solid object. E.g. interaction of aeroplane wings with air, study of motion of air around the object is called flow field, which helps in calculating various forces and moments on the exposed object. The other aspect of aerodynamic is internal aerodynamic which deals with the flow through passages in solid objects e.g. Study of air flow through jet engine or through an air conditioning pipe. Meteorology is a branch of the atmospheric sciences which includes atmospheric chemistry and atmospheric physics
