Ice scale numbers for source terms in w3srcemd.F90

[chezh583]

Hi, I found ice scale numbers for source terms in WW3/model/src/w3srcemd.F90 might be incorrect, the codes (line921-924) are below:

ICESCALELN = MAX(0.,MIN(1.,1.-ICE*ICESCALES(1)))
ICESCALEIN = MAX(0.,MIN(1.,1.-ICE*ICESCALES(2)))
ICESCALENL = MAX(0.,MIN(1.,1.-ICE*ICESCALES(3)))
ICESCALEDS = MAX(0.,MIN(1.,1.-ICE*ICESCALES(4)))
# the default value for ICESCALES is 1

It is clear that wind source and dissipation term is scaled by (1-c), because models assume they work on open water part. However, the nonlinear term is also scaled by (1-c) here in the code, which is different from the user manual saying that it is unchanged (or scaled by 1).

Solved. Some say the scaling for Snl is (1-c), and some say the scaling for Snl is 1. In WW3, the default setting is (1-c)
