subroutine	CALMCVG (Q1D, U1D, V1D, QCNVG)

Detailed Description

Subroutine that computes moisture convergence.

 Given specific humidity, Q, and the U-V wind components
 This routine evaluates the vector operation, 
                  DEL DOT (Q*VEC)
 where,
    DEL is the vector gradient operator,
    DOT is the standard dot product operator, and
    VEC is the vector wind.
 Minus one times the resulting scalar field is the 
 moisture convergence which is returned by this routine.

Parameters

[in]	Q1D	- Specific humidity at P-points (kg/kg).
[in]	U1D	- U wind component (m/s) at P-points.
[in]	V1D	- V wind component (m/s) at P-points.
[out]	QCNVG	- Moisture convergence (1/s) at P-points.
