  1. Modeling fog in complex topography with tBM Olivier Liechti, Winterthur, Switzerland

  2. Outline • findings of the 1d model intercomparison • present status of tBM • preliminary results • outlook

  3. 1-d MIC • increase of the vertical resolution • introduce kinetic energy into the vertical mixing • apply tBM to complex topography • coupling of tBM to NWP model • verification

  4. Paris CDG Lindenberg Complex topography (dz=10m)

  5. Frankfurt a.M. Munich FJS Complex topography (dz=10m)

  6. Zurich airport Uster Complex topography (dz=10m)

  7. tBM real-time visualization

  8. Real-time visualization of tBM case studies nocturnal cooling dew deposition formation of fog dissipation of fog Preliminary results

  9. use of the radiation scheme for stratiform clouds (cloud top cooling) use of vertical profiles from NWP add wind to the vertical mixing scheme 2-d version of tBM for drainage flows tuning of tBM with observations verification with observations Outlook
