在b. Other options for long simulations (new in Version 3.1):中关于sst_skin的描述只有下面一样注释
...

应该是两个试验：
a. sst_update = 1             sst_skin=0
b. sst_update = 1             sst_skin=1

你好～我把io_form_auxinput4 = 2
auxinput4_inname = “wrflowinp_d<domain>”
auxinput4_interval = 360, 360, 360,
加入到namelist。wps中运行.／geogrid.exe就出错阿～～

谢谢你的回复～～正在摸索中

不知兄台  台风模拟到哪一步了 我也在做类似的，我做完 SST升级 ，3D ，现在也在做 OML ，不过 OML 稍微碰到点问题？？

SST not changing with Ocean Mixed Layer Model on

Postby gns5000 &#187; Thu Feb 23, 2012 11:42 am
Hello,

I am currently running WRF with omlcall=1, oml_hml0 = 10, and oml_gamma = 1 (very stratified ocean state). With sst_update=0 (constant SST from the Real-Time Global High-Res product), I run WRF and SST doesn't change throughout the run. However, ocean mixed layer depth and ocean mixed layer temperature change accordingly to how the ocean mixed layer model should run. 2-m temperature changes accordingly as well.

I also run WRF with sst_update=1 with the ocean mixed layer model turned on and produce the same results with SST not changing.

Is the SST actually changing in the model but not being output correctly? The model results seem to show this (e.g. winds change) but SST seems to stay constant. I feel like anyone who turns on this ocean mixed layer model would love to see the SST change accordingly.

Thanks for your help,
Greg

Solution to above problem (provided by wrfhelp): TSK is the model skin temp, and over the ocean, it is the model SST.

It seems that "SST" is updated only according to what is provided in the boundary conditions, but "TSK" is what the model produces as output for skin temperature.
