Introduction : | !! -------------- | !! Every ice-covered grid cell is characterized by a series of state | !! variables. To account for unresolved spatial variability in ice | !! thickness, the ice cover in divided in ice thickness categories. | !! | !! Sea ice state variables depend on the ice thickness category | !! | !! Those variables are divided into two groups | !! * Extensive (or global) variables. | !! These are the variables that are transported by all means | !! * Intensive (or equivalent) variables. | !! These are the variables that are either physically more | !! meaningful and/or used in ice thermodynamics | !! | !! Routines in limvar.F90 perform conversions | !! - lim_var_glo2eqv : from global to equivalent variables | !! - lim_var_eqv2glo : from equivalent to global variables | !! | !! For various purposes, the sea ice state variables have sometimes | !! to be aggregated over all ice thickness categories. This operation | !! is done in : | !! - lim_var_agg | !! | !! in icestp.F90, the routines that compute the changes in the ice | !! state variables are called | !! - lim_dyn : ice dynamics | !! - lim_trp : ice transport | !! - lim_itd_me : mechanical redistribution (ridging and rafting) | !! - lim_thd : ice halo-thermodynamics | !! - lim_itd_th : thermodynamic changes in ice thickness distribution | !! and creation of new ice | !! | !!
