Modify idealised tropical cyclone cases

[yli.ouc]

Dear all,

I'm trying to run some idealised tropical cyclone cases within the coupled COAWST model, which only supports 'real' cases. I can try the em_tropical_cyclone case and modify the initial conditions via changing dyn_em/module_initialize_tropical_cyclone.F, but I have no idea how to do so for a 'real' case. I guess I need some 'idealised' GFS files to create wrfinput and wrfbdy. I have found a tutorial on HWRF's website (Idealized Run | dtcenter.org). However, HWRF uses different input files to specify the initial vortex (sound.d, storm.center, etc.). Is there any way to generate the GFS file for WRF?

Thank you.
Y

HI,
HWRF is based on WRF0-NMM dynamic core and it is quite different to WRF-ARW core.
I am not quote familiar with the COAST model, and I dimly know it is WRF coupled with ocean model. Please let me know if I am wrong.

Suppose COAWST is WRF coupled with ocean model, then to run the ideal WRF case, I guess you need to turn off the coupling and simply run it as standard WRF. Hopefully the WRF structure in COAWST is not changed. Otherwise I am suspicious that you must modify the codes.

Hope this is helpful for you. I also suggest you contact COAWST people to get more information.

Hi Ming,

Thanks for the reply. I'll try the ideal wrf first.

Best regards,
