I was wondering if it is possible to get the resolved scale TKE as an output variable. It seems to me that using km_opt=2 in the ‘namelist’ should give the resolved TKE as an output, but I do not find it in my netcdf output file. I found the following in the ARW description document:<o:p></o:p></p><p class=MsoNormal style='text-autospace:none'>“Optionally, turbulent kinetic energy and any number of scalars such as water vapor mixing ratio, rain/snow mixing ratio, cloud water/ice mixing ratio, and chemical species and tracers.”<o:p></o:p></p><p class=MsoNormal>Maybe this is only referring to the output obtained when using a PBL scheme?<o:p></o:p></p><p class=MsoNormal>Also is it possible to get information about the velocity perturbation as an output (e.g. u’, v’, w’ or maybe the second moment)? I believe that the U, V, W output variables are the full velocities. If I have to compute TKE and velocity fluctuation in post processing then I will have a lot of output data from the WRF run and post processing will be memory intensive.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Anders Nottrott<o:p></o:p></p></div></body></html>
