Hi Teresa,<br>
<br>
WRF-NMM is in operational use in our service for two years, now<br>
I am doing some tests of nesting different domains and have exactly <br>
the same problem with shifting fields when plot nested domain. Part <br>
of namelist defining domains looks like this:<br>
<br>
max_dom = 2,<br>
e_we = 260, 140,<br>
e_sn = 450, 290,<br>
<br>
dx = 0.078536,<br>
dy = 0.075285,<br>
<br>
i_parent_start = 1,150,<br>
j_parent_start = 1,120,<br>
<br>
And plot of 2m temperature for nested domain is:<br>
<br>
<img alt="" src="cid:part1.02090109.06050404@meteo.yu" height="600"
width="800"><br>
<br>
Changing in the projection and boundaries doesn't solve the problem.<br>
Central latitude and longitude is defined only in namelist.wps, wrfout<br>
files contain information about central latitude for parent domain only<br>
<br>
:CEN_LAT = 48.f ;<br>
:CEN_LON = 8.f ;<br>
<br>
but GRIB file that copygb creates has information of center
latitude<br>
which is good, even fields are slightly rotated to the west.<br>
<br>
GRID NUMBER = 255<br>
IGDS= 0 255 203 139
289 40008 12165 136 43296
17345 26 25 64 0
0 0 0 0<br>
<br>
Did you solve this problem? Can you, please, explain me what you did?<br>
<br>
Thank you in advance.<br>
