[1218]	1058	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.

[1218]	1062	!! --> If ocean stress was really received:
[888]	1063	!!
[1218]	1064	!! - transform the received ocean stress vector from the received
	1065	!! referential and grid into an atmosphere-ocean stress in
	1066	!! the (i,j) ocean referencial and at the ocean velocity point.
	1067	!! The received stress are :
	1068	!! - defined by 3 components (if cartesian coordinate)
	1069	!! or by 2 components (if spherical)
	1070	!! - oriented along geographical coordinate (if eastward-northward)
	1071	!! or along the local grid coordinate (if local grid)
	1072	!! - given at U- and V-point, resp. if received on 2 grids
	1073	!! or at T-point if received on 1 grid
	1074	!! Therefore and if necessary, they are successively
	1075	!! processed in order to obtain them
	1076	!! first as 2 components on the sphere
	1077	!! second as 2 components oriented along the local grid

[1218]	1595	!! emp_ice = sublimation - solid precipitation as liquid
	1596	!! precipitation are re-routed directly to the ocean and
[6722]	1597	!! calving directly enter the ocean (runoffs are read but included in trasbc.F90)
	1598	!! * solid precipitation (sprecip), used to add to qns_tot
[1218]	1599	!! the heat lost associated to melting solid precipitation
	1600	!! over the ocean fraction.
[6722]	1601	!! * heat content of rain, snow and evap can also be provided,
	1602	!! otherwise heat flux associated with these mass flux are
	1603	!! guessed (qemp_oce, qemp_ice)
[1218]	1604	!!
[6722]	1605	!! - the fluxes have been separated from the stress as
	1606	!! (a) they are updated at each ice time step compare to
	1607	!! an update at each coupled time step for the stress, and
	1608	!! (b) the conservative computation of the fluxes over the
	1609	!! sea-ice area requires the knowledge of the ice fraction
	1610	!! after the ice advection and before the ice thermodynamics,
	1611	!! so that the stress is updated before the ice dynamics
