Description

  1. 798 (limthd_dif.F90)

$Id: limthd_dif.F90 2528 2010-12-27 17:33:53Z rblod $

The convention is that the latent heat flux should never be positive.

The latent heat flux is updated following the surface temperature computation in limthd_dif.F90:
qla_ice_1d (ji) = qla_ice_1d (ji) + &

dqla_ice_1d(ji) * ( t_su_b(ji) - ztsuold(ji) )

To ensure the negativity of the latent heat flux, this should instead read:

qla_ice_1d (ji) = MAX( 0.e0, qla_ice_1d (ji) + dqla_ice_1d(ji) * ( t_su_b(ji) - ztsuold(ji) ) )
