01:10:00 Yann Seity: @Jeanette : Thanks for this interesting talk ! You showed a comparison with LES@100m. Which model is used for the LES simulation ? 01:49:00 Gareth: Slides not updating online (for me anyway) 02:47:49 Matthias Raschendorfer, Naumburg: Peter, what did you change with regard to saturation adjustment despite the SPPT issue, are you maybe turning to a sub-grid scale adjustment? 02:53:30 Thomas Rieutord: Do you use some kind of EDA from ERA5 to initialize the reforecast? How do you deal with the difference of resolution between ERA5 and the current config (still for reforecast)? 03:27:52 Oliver Fuhrer : Hi Nils, thanks for a great presentation! With a number of DTs based on different models / model components running in different HPC centres, data governance (beyond ECMWFs traditional scope) will become increasingly important. Can you talk a bit more about the specific approach DestinE is taking here? 03:33:11 Oliver Fuhrer : Thanks! 03:35:36 Yann Seity: @Dimitri, Sorry, I had pb with my microphone. Hope I managed to fix it for next talks. 03:58:20 Matthias Raschendorfer, Naumburg: Sylvie, how have synoptic standard levels at 2m and 10m level been defined within an urban area (e.g. within the street canyons above the pavement, or along surfaces covering all surfaces including the buildings at a given distance)? 04:29:10 Matthias Raschendorfer, Naumburg: Humphrey, even at grid-scales of about 100m, the effective horizontal numerical resolution, which is at least 5 times less, cannot resolve individual buildings. So how do you represent the large roughness layer of a city extending up to a height of, say, 40m in model? Is this layer vertically resolved (meaning, what is the depth of the lowermost atmospheric model levels compared to the depth of this roughness layer)? 04:41:45 Balazs Szintai (OMSZ): we reconvene at 14:15 CEST 06:36:01 Alan Hally: Thanks Alejandro, how did you decide upon the subset of parameters to perturb in your random microphysical perturbations? Some initial sensitivity analysis or discussion with physics experts? 06:51:48 Stéphane Vannitsem: Any question for Aline? 07:08:40 Stéphane Vannitsem: Any question for Balazs? 08:16:45 Lech Łobocki: What about the inclination of the terrain on turbulence? Is it neglected, or treated in some way? 08:23:00 Bazile: Do you use SLHD on tke and tpe with the 3d terms? 08:23:21 Matthias Raschendorfer, Naumburg: Petra, there are actually similarities with our approach introducing 3D effects into TURBDIFF. However, doesn’t your approach of applying the horizontal length scale of the numerical grid to TKE violate the constraint of isotropy applied for turbulence closure? In our approach, such a (large) horizontal length scale is applied to particular non-turbulent horizontal circulations. 09:21:37 Lech Łobocki: There is no Dynamics section at the Google Drive
