C The calculations of Moorthi and Suarez (1992, MWR) are |
| 1367 |
C contained in the CLOUD routine. |
| 1368 |
C It is probably advisable, at least initially, to treat CLOUD |
| 1369 |
C as a black box that computes the single cloud adjustments. RAS, |
| 1370 |
C on the other hand, can be tailored to each GCMs configuration |
| 1371 |
C (ie, number and placement of levels, nature of boundary layer, |
| 1372 |
C time step and frequency with which RAS is called). |
| 1373 |
C |
| 1374 |
C |
| 1375 |
C Input: |
| 1376 |
C ------ |
| 1377 |
C |
| 1378 |
C LEN : The inner dimension of update and input arrays. |
| 1379 |
C |
| 1380 |
C LENC : The run: the number of soundings processes in a single call. |
| 1381 |
C RAS works on the first LENC of the LEN soundings |
| 1382 |
C passed. This allows working on pieces of the world |
| 1383 |
C say for multitasking, without declaring temporary arrays |
| 1384 |
C and copying the data to and from them. This is an f77 |
| 1385 |
C version. An F90 version would have to allow more |
| 1386 |
C flexibility in the argument declarations. Obviously |
| 1387 |
C (LENC<=LEN). |
| 1388 |
C |
| 1389 |
C K : Number of vertical layers (increasing downwards). |
| 1390 |
C Need not be the same as the number of layers in the |
| 1391 |
C GCM, since it is the outer dimension. The bottom layer |
| 1392 |
C (K) is the subcloud layer. |
| 1393 |
C |
| 1394 |
C IC : Detrainment level to check for presence of convection |
| 1395 |
C |
| 1396 |
C RASALF : Relaxation parameter (< 1.) for present cloud-type |
| 1397 |
C |
| 1398 |
C SETRAS : Logical parameter to control re-calculation of |
| 1399 |
C saturation specific humidity and mid level P**kappa |
| 1400 |
C |
| 1401 |
C FRAC : Fraction of the PBL (layer K) mass allowed to be used |
| 1402 |
C by a cloud-type in time DT |
| 1403 |
C |
| 1404 |
C CP : Specific heat at constant pressure |
| 1405 |
C |
| 1406 |
C ALHL : Latent Heat of condensation |
| 1407 |
C |
| 1408 |
C RKAP : R/Cp, where R is the gas constant |
| 1409 |
C |
| 1410 |
C GRAV : Acceleration due to gravity |
| 1411 |
C |
| 1412 |
C P00 : A reference pressure in hPa, useually 1000 hPa |
| 1413 |
C |
| 1414 |
C CRTMSF : Critical value of mass flux above which cloudiness at |
| 1415 |
C the detrainment layer of that cloud-type is assumed. |
| 1416 |
C Affects only cloudiness calculation. |
| 1417 |

C Updated but not initialized by RAS. |
| 1426 |
C |
| 1427 |
C PRS : 2D array of dimension (LEN,K+1) containing pressure |
| 1428 |
C in hPa at the interfaces of K-layers from top of the |
| 1429 |
C atmosphere to the bottom. Not modified. |
