[Wrf-users] SST update versus SST used in initial conditions

[Elena Maria Pison San Pedro]

Hi Andrea,

 

Thanks for your answer, however even if I don't include SST info via WPS
in the met_files, only using sst_update (daily SST from
polar.ncep.noaa.gov) I  can see that there is initial conditions created
containing this SST info(wrflow_input*). The results are also different
from using or not SST_udate (as explained in the ARW_Users's guide-
"Using sst_update option").

 

So my question is more on what is the difference in updating through
wrflow_input or using the SST info through metfiles? 

 

A million of thanks!

 

Elena

WPS (your second line) makes the file containing the SSTs that WRF reads
in when sst_update=1 (your first line).
Hope this helps,

Hi,

 

I would like to know which is the difference if there is any between:

-        updating daily SST information into the model via sst_update =1
in namelist.input and

-       Introducing SST information via WPS with the "prefix = 'SST' and
fg_name = 'FILE' " in namelist.wps?

 

Thanks a lot in advance!

 

Kindly regards,

Elena
