[MITgcm-support] Weird cooling with simple EXF setup

[Yilang Xu]

Hi all, 

 

My last email did not get through the pipeline after 1hour, so sorry if a repeated message shows up later. 

 

I am testing EXF package, and am using the default EXF_OPTIONS.h file. In my data.exf, I have the following input, 

Air temperature 10 degC all over the domain, with “exf_offset_atemp  = 273.15” added;

Humidity 0.0001 all over the domain;

Vwind ramps from 0 to 20m/s within certain area; 

For uwindfile, precipfile, lwdownfile, swdownfile, runoffFile, I have input files with value 0 all over the domain. 

 

The ocean is initialized with 5 degC in data. During the runs, the ocean keeps cooling, with strong positive hflux and lwflux in STDOUT.0000. I checked exf_atemp in STDOUT, it is 283.15. So I am not sure why the ocean is getting colder even the air is warmer. 

 

My data.exf and STDOUT files are uploaded through Google drive.

Appreciate it if anyone would help with this problem. 

 

Thanks,

Yilang
