3 !-------------------------------------------------------------------------------
4 ! Authors: P. Le Van , Fr. Hourdin.
5 !-------------------------------------------------------------------------------
6 ! Purpose: Compute mass flux at s levels.
7 IMPLICIT NONE
8 include "dimensions.h"
9 include "paramet.h"
10 include "comgeom.h"
11 !===============================================================================
12 ! Arguments:
13 REAL, INTENT(IN) :: massebx(ip1jmp1,llm)
14 REAL, INTENT(IN) :: masseby(ip1jm ,llm)
15 REAL, INTENT(IN) :: vcont (ip1jm ,llm)
16 REAL, INTENT(IN) :: ucont (ip1jmp1,llm)
17 REAL, INTENT(OUT) :: pbaru (ip1jmp1,llm)
18 REAL, INTENT(OUT) :: pbarv (ip1jm ,llm)
19 !===============================================================================
20 ! Method used: A 2 equations system is solved.
21 ! * 1st one describes divergence computation at pole point nr. i (i=1 to im):
22 ! (0.5*(pbaru(i)-pbaru(i-1))-pbarv(i))/aire(i) = - SUM(pbarv(n))/aire pole
23 ! * 2nd one specifies that mean mass flux at pole is equal to 0:
24 ! SUM(pbaru(n)*local_area(n))=0
25 ! This way, we determine additive constant common to pbary elements representing
26 ! pbaru(0,j,l) in divergence computation equation for point i=1. (i=1 to im)
27 !===============================================================================
28 ! Local variables:
29 REAL :: sairen, saireun, ctn, ctn0, apbarun(iip1)
30 REAL :: saires, saireus, cts, cts0, apbarus(iip1)
31 INTEGER :: l, i
