Dear all,
I am currently involved in more research projects, where we would need 3D information on orographic GWD at least on daily basis. Right now we are using accelogw output from CMAM, but it would be desirable to have similar data from other models with different GW parametrizations..
E.g. some models participating at CCMI community simulations have 3D GWD on monthly basis. Possible to find daily 3D GWD data anywhere?
Thanks in advance,
Petr.
Hi Petr,
if you are not particularly constrained to the CCMi scenarios there are some current and future projects where you may be able to obtain daily orographic GW diagnostics. There will be DynVarMIP within CMIP6:
Gerber, E. P. and Manzini, E.: The Dynamics and Variability Model Intercomparison Project (DynVarMIP) for CMIP6: assessing the stratosphere–troposphere system, Geosci. Model Dev., 9, 3413-3425, doi:10.5194/gmd-9-3413-2016, 2016
which will be releasing data from participating models over the next couple of years. Currently, the only other possible option (outside of approaching individual modelling groups) is with the SPARC-QBOi project:
http://www.sparc-climate.org/activities/quasi-biennial-oscillation/
Daily 3D data might be a little hard to come by, but participating groups may still have logged these data..
ciao,
Scott.
Dear Petr,
Recently Andrey Koval arranged a new orographic GWD paremeterization. See, for instance, the reference
Gavrilov N.M., Koval A.V., Pogoreltsev A.I., and Savenkova E.N. Simulating influences of QBO phases and orographic gravity wave forcing on planetary waves in the middle atmosphere. Earth, Planets and Space (2015) 67:86, DOI 10.1186/s40623-015-0259-2.
I think that you can find this paper at Research Gate. Or you can contact him directly - I called him. His e-mail: [email protected] or koval.spbu@gmail. com
Regards, Alex
Hi Scott, thanks for summarizing the options for me! I will try to approach some of the QBOi participating groups.
Dear Alex, thank you for pointing up the paper. I also have the possibility to use MUAM, but we use it for theoretical experiments rather than for multi-year climate simulations.
Best regards,
Petr.
