MPAS-A predicted precipitation is underestimated

[Ming Chen]

Hi Boštjan,

Unfortunately we don't run regional MPAS over central Europe or other regions nearby.

When you compare MPAS with WRF, please note that you should keep as identical as possible the physics and dynamics options as well as other important factors like grid size, vertical levels, etc. Any differences may lead to differences in the final simulations.

Thanks for all the help so far. I have an additional question when repeating the example of 21.8.2025. The precipitation intensity is much better with the GFS reanalysis data. However, a comparison with the WRF results of that day shows that the precipitation moved over Slovenia significantly faster than the MPAS-A model results show. In general, the simulations look like the air masses are moving relatively slowly over central Europe. From a feeling, I would say that it looks like the initial conditions are well taken into account in the simulation, and the boundary conditions have less influence. Is it possible to get some MPAS model results for central Europe somewhere that I could compare my results with?

Regards, Boštjan

Hello,


thank you for answer, I have just one more question. Are there some results online over some other regions?
I could test my region and settings there.

Regards,
Boštjan

We run global MPAS simulations at the resolution of 3.75km. Please see details here.

Note that this is global run and the results could be different to regional simulations. Hope this is helpful for you.
