Hi Michael,My personal experience is that it is still far from being stable. I tested it to simulate Hurricane Katrina using 3 km horizontal resolution plus 23 vertical layer (nested under 27 km case that covers almost entire Atlantic) but it crashes after couple of days even if i decrease the time step to very small numbers. It also creates some patchy output in the high resolution (at least in my version) case without any clue why. So, for non-hydrostatic applications i think you need to wait little bit more or you could choose any other model such as WRF, COSMO etc.Regards,--ufukFrom: "Michael Notaro" <mnotaro@wisc.edu>

As far as I can tell, these papers all use the hydrostatic version of the model,
not the non-hydrostatic, convection-resolving version.

Are there any publications applying the non-hydrostatic version of RegCM4?
Or could anyone share their experience using the non-hydrostatic version,
in terms of its performance and potential challenges?
Thanks, Michael
