| 50 | !! Introduction : | |
|---|
| 51 | !! -------------- | |
|---|
| 52 | !! Every ice-covered grid cell is characterized by a series of state | |
|---|
| 53 | !! variables. To account for unresolved spatial variability in ice | |
|---|
| 54 | !! thickness, the ice cover in divided in ice thickness categories. | |
|---|
| 55 | !! | |
|---|
| 56 | !! Sea ice state variables depend on the ice thickness category | |
|---|
| 57 | !! | |
|---|
| 58 | !! Those variables are divided into two groups | |
|---|
| 59 | !! * Extensive (or global) variables. | |
|---|
| 60 | !! These are the variables that are transported by all means | |
|---|
| 61 | !! * Intensive (or equivalent) variables. | |
|---|
| 62 | !! These are the variables that are either physically more | |
|---|
| 63 | !! meaningful and/or used in ice thermodynamics | |
|---|
| 64 | !! | |
|---|
| 65 | !! Routines in limvar.F90 perform conversions | |
|---|
| 66 | !! - lim_var_glo2eqv : from global to equivalent variables | |
|---|
| 67 | !! - lim_var_eqv2glo : from equivalent to global variables | |
|---|
| 68 | !! | |
|---|
| 69 | !! For various purposes, the sea ice state variables have sometimes | |
|---|
| 70 | !! to be aggregated over all ice thickness categories. This operation | |
|---|
| 71 | !! is done in : | |
|---|
| 72 | !! - lim_var_agg | |
|---|
| 73 | !! | |
|---|
| 74 | !! in icestp.F90, the routines that compute the changes in the ice | |
|---|
| 75 | !! state variables are called | |
|---|
| 76 | !! - lim_dyn : ice dynamics | |
|---|
| 77 | !! - lim_trp : ice transport | |
|---|
| 78 | !! - lim_itd_me : mechanical redistribution (ridging and rafting) | |
|---|
| 79 | !! - lim_thd : ice halo-thermodynamics | |
|---|
| 80 | !! - lim_itd_th : thermodynamic changes in ice thickness distribution | |
|---|
| 81 | !! and creation of new ice | |
