C Purpose: |
| 6 |
|
|
C To interpolate an arbitrary quantity from the 'dynamics' eta (pstar) |
| 7 |
|
|
C grid to the higher resolution physics grid |
| 8 |
|
|
C Algorithm: |
| 9 |
|
|
C Routine works one layer (edge to edge pressure) at a time. |
| 10 |
|
|
C Dynamics -> Physics retains the dynamics layer mean value, |
| 11 |
|
|
C weights the field either with the profile of the physics grid |
| 12 |
|
|
C wind speed (for U and V fields), or uniformly (T and Q) |
| 13 |
|
|
C |
| 14 |
|
|

| 26 |
|
|
C windphy.. [im,jm,lmphy] Magnitude of the wind on the output levels |
| 27 |
|
|
C pephy.... [im,jm,lmphy+1] Pressures at bottom edges of output levels |
| 28 |
|
|
C lmphy.... Vertical Dimension of Output |
| 29 |
|
|
C nlperdyn. [im,jm,lmdyn] Highest Physics level in each dynamics level |
| 30 |
|
|
C flg...... Flag to indicate field type (0 for T or Q, 1 for U or V) |
| 31 |
|
|
C |
| 32 |
|
|
C Output: |
| 33 |
|
|
C qphy..... [im,jm,lmphy] Quantity at output grid (physics grid) |
| 34 |
|
|
C |
| 35 |
|
|
C Notes: |
| 36 |
|
|
C 1) This algorithm assumes that the output (physics) grid levels |
| 37 |
|
|
C fit exactly into the input (dynamics) grid levels |
