61	! SUBPROGRAM: ADVE HORIZONTAL AND VERTICAL ADVECTION
62	! PRGRMMR: JANJIC ORG: W/NP22 DATE: 93-10-28
63	!
64	! ABSTRACT:
65	! ADVE CALCULATES THE CONTRIBUTION OF THE HORIZONTAL AND VERTICAL
66	! ADVECTION TO THE TENDENCIES OF TEMPERATURE AND WIND AND THEN
67	! UPDATES THOSE VARIABLES.
68	! THE JANJIC ADVECTION SCHEME FOR THE ARAKAWA E GRID IS USED
69	! FOR ALL VARIABLES INSIDE THE FIFTH ROW. AN UPSTREAM SCHEME
70	! IS USED ON ALL VARIABLES IN THE THIRD, FOURTH, AND FIFTH
71	! OUTERMOST ROWS. THE ADAMS-BASHFORTH TIME SCHEME IS USED.
72	!
73	! PROGRAM HISTORY LOG:
74	! 87-06-?? JANJIC - ORIGINATOR
75	! 95-03-25 BLACK - CONVERSION FROM 1-D TO 2-D IN HORIZONTAL
76	! 96-03-28 BLACK - ADDED EXTERNAL EDGE
77	! 98-10-30 BLACK - MODIFIED FOR DISTRIBUTED MEMORY
78	! 99-07- JANJIC - CONVERTED TO ADAMS-BASHFORTH SCHEME
79	! COMBINING HORIZONTAL AND VERTICAL ADVECTION
80	! 02-02-04 BLACK - ADDED VERTICAL CFL CHECK
81	! 02-02-05 BLACK - CONVERTED TO WRF FORMAT
82	! 02-08-29 MICHALAKES - CONDITIONAL COMPILATION OF MPI
83	! CONVERT TO GLOBAL INDEXING
84	! 02-09-06 WOLFE - MORE CONVERSION TO GLOBAL INDEXING
85	! 04-05-29 JANJIC,BLACK - CRANK-NICHOLSON VERTICAL ADVECTION
86	! 04-11-23 BLACK - THREADED

2944	! New routines added by Georg Grell to handle advection more like ARW
2945	! core. Instead of VAD2/HAD2 that advect TKE, specific humidity, and
2946	! condensed water species all in one routine, we call VAD2/HAD2_SCAL
2947	! with multidimensioned arrays to advect each variable. For purposes
2948	! here, solve_nmm.F calls this routine once for TKE, then again for
2949	! all the species held in the moist array (qv, qc, qi, qr, qs, qg),
2950	! then call again for number concentrations held in scalar array (qni).
2951	! The dummy argument lstart is the starting index of the multidimensioned
2952	! array for starting the advection since the 1st index of moist and
2953	! scalar are actually empty placeholders (and the 2nd element is vapor,
2954	! then qc, etc.) When calling with single 3D array (like TKE), just
2955	! set NUM_SCAL=1 and lstart=1. The variable to advect is called SCAL
2956	! herein.
