43	! SUBPROGRAM: PFDHT DIVERGENCE/HORIZONTAL OMEGA-ALPHA
44	! PRGRMMR: JANJIC ORG: W/NP22 DATE: 93-10-28
45	!
46	! ABSTRACT:
47	! PFDHT CALCULATES THE PRESSURE GRADIENT FORCE, UPDATES THE
48	! VELOCITY COMPONENTS DUE TO THE EFFECT OF THE PRESSURE GRADIENT
49	! AND CORIOILS FORCES, COMPUTES THE DIVERGENCE INCLUDING THE
50	! MODIFICATION PREVENTING GRAVITY WAVE GRID SEPARATION, AND
51	! CALCULATES THE HORIZONTAL PART OF THE OMEGA-ALPHA TERM.
52	! (THE PART PROPORTIONAL TO THE ADVECTION OF MASS ALONG
53	! COORDINATE SURFACES).
54	!
55	! PROGRAM HISTORY LOG:
56	! 87-06-?? JANJIC - ORIGINATOR
57	! 95-03-25 BLACK - CONVERSION FROM 1-D TO 2-D IN HORIZONTAL
58	! 96-03-29 BLACK - ADDED EXTERNAL EDGE
59	! 98-10-30 BLACK - MODIFIED FOR DISTRIBUTED MEMORY
60	! 02-02-01 BLACK - REWRITTEN FOR WRF CODING STANDARDS
61	! 04-02-17 JANJIC - REMOVED UPDATE OF TEMPERATURE
