[MITgcm-devel] depressed Eta and sIceLoad

[Martin Losch]

I have to go home now, but here is my preliminary conclusion about  
advection of snow and flooding:
flooding will take care of any extra snow, however, if there is too  
much snow production, the snow will be converted into ice which melts  
eventually and makes the surface extremely fresh (if there is too  
much snow). Although I can fight a symptom with this flooding, it  
just moves the problem elsewhere. so in my case there is too much  
snow and I can't find the reason why. My precipitation can reach 50cm/ 
y in the critical areas, which can mean  1.5m/y of snow according to  
growth.F (if FICE>0, which is probably not the case all year round),  
which is about consistent with my observation of up to 100m in  
100years. For some reason the snow does not melt. I would be grateful  
for any ideas.
