49	! ABSTRACT:
50	! PFDHT CALCULATES THE PRESSURE GRADIENT FORCE, UPDATES THE
51	! VELOCITY COMPONENTS DUE TO THE EFFECT OF THE PRESSURE GRADIENT
52	! AND CORIOILS FORCES, COMPUTES THE DIVERGENCE INCLUDING THE
53	! MODIFICATION PREVENTING GRAVITY WAVE GRID SEPARATION, AND
54	! CALCULATES THE HORIZONTAL PART OF THE OMEGA-ALPHA TERM.
55	! (THE PART PROPORTIONAL TO THE ADVECTION OF MASS ALONG
56	! COORDINATE SURFACES).
