C The calculations of Moorthi and Suarez (1992, MWR) are |
| 1466 |
C contained in the CLOUD routine. |
| 1467 |
C It is probably advisable, at least initially, to treat CLOUD |
| 1468 |
C as a black box that computes the single cloud adjustments. RAS, |
| 1469 |
C on the other hand, can be tailored to each GCMs configuration |
| 1470 |
C (ie, number and placement of levels, nature of boundary layer, |
| 1471 |
C time step and frequency with which RAS is called). |
| 1472 |
C |
| 1473 |
C |
| 1474 |
C Input: |
| 1475 |
C ------ |
| 1476 |
C |
| 1477 |
C lng : The inner dimension of update and input arrays. |
| 1478 |
C |
| 1479 |
C LENC : The run: the number of soundings processes in a single call. |
| 1480 |
C RAS works on the first LENC of the lng soundings |
| 1481 |
C passed. This allows working on pieces of the world |
| 1482 |
C say for multitasking, without declaring temporary arrays |
| 1483 |
C and copying the data to and from them. This is an f77 |
| 1484 |
C version. An F90 version would have to allow more |
| 1485 |
C flexibility in the argument declarations. Obviously |
| 1486 |
C (LENC<=lng). |
| 1487 |
C |
| 1488 |
C K : Number of vertical layers (increasing downwards). |
| 1489 |
C Need not be the same as the number of layers in the |
| 1490 |
C GCM, since it is the outer dimension. The bottom layer |
| 1491 |
C (K) is the subcloud layer. |
| 1492 |
C |
| 1493 |
C IC : Detrainment level to check for presence of convection |
| 1494 |
C |
| 1495 |
C RASALF : Relaxation parameter (< 1.) for present cloud-type |
| 1496 |
C |
| 1497 |
C SETRAS : Logical parameter to control re-calculation of |
| 1498 |
C saturation specific humidity and mid level P**kappa |
| 1499 |
C |
| 1500 |
C FRAC : Fraction of the PBL (layer K) mass allowed to be used |
| 1501 |
C by a cloud-type in time DT |
| 1502 |
C |
| 1503 |
C CP : Specific heat at constant pressure |
| 1504 |
C |
| 1505 |
C ALHL : Latent Heat of condensation |
| 1506 |
C |
| 1507 |
C RKAP : R/Cp, where R is the gas constant |
| 1508 |
C |
| 1509 |
C GRAV : Acceleration due to gravity |
| 1510 |
C |
| 1511 |
C P00 : A reference pressure in hPa, useually 1000 hPa |
| 1512 |
C |
| 1513 |
C CRTMSF : Critical value of mass flux above which cloudiness at |
| 1514 |
C the detrainment layer of that cloud-type is assumed. |
| 1515 |
C Affects only cloudiness calculation. |
| 1516 |
C |
| 1517 |
C POI : 2D array of dimension (lng,K) containing potential |
| 1518 |
C temperature. Updated but not initialized by RAS. |
| 1519 |
C |
| 1520 |
C QOI : 2D array of dimension (lng,K) containing specific |
| 1521 |
C humidity. Updated but not initialized by RAS. |
| 1522 |
C |
| 1523 |
C UOI : 3D array of dimension (lng,K,NTRACER) containing tracers |
| 1524 |
C Updated but not initialized by RAS. |
| 1525 |
C |
| 1526 |
C PRS : 2D array of dimension (lng,K+1) containing pressure |
| 1527 |
C in hPa at the interfaces of K-layers from top of the |
| 1528 |
C atmosphere to the bottom. Not modified. |
| 1529 |
C |

C PRJ : 2D array of dimension (lng,K+1) containing (PRS/P00) ** |
| 1531 |
C RKAP. i.e. Exner function at layer edges. Not modified. |
| 1532 |
C |
