Vertical Motion
Vertical Pressure GradientA pressure gradient is a change in pressure over a distance, directed toward increasing values. We must remember that pressure changes dramatically with height, forming a pressure gradient directed toward higher values (down). This in turn produces a very strong pressure gradient force directed upward.This pressure gradient is about four orders of magnitude larger in magnitude than the horizontal PGF. However, it is also balanced by a strong force -- gravity. Confused? Have a question?
