Per la serie di seminari in meteorologia ambientale dell’Università di Trento, giovedì 23 maggio 2024 alle ore 14:30, Bruno Neininger, di MetAir, terrà un seminario dal titolo: AlpTherm3d: A heuristic Lagrangian downscaling algorithm for assessing convection over complex terrain. Il seminario si terrà in presenza nell’aula 1P (primo piano) del DICAM – Università di Trento, in via Masiano 77, e sarà possibile seguirlo in streaming su Zoom attraverso il seguente link: https://unitn.zoom.us/j/84003106761 Meeting ID: 840 0310 6761 Passcode: 183780 AbstractAlpTherm is a tool for assessing convection for air sports, with a firstoperational version dating back to 1993. I will therefore outline thehistorical background and the special motivation for this appliedscience.AlpTherm3d is fully three-dimensional, using a high resolution for theorography, and is adaptable to any region where digital terrain data(e.g. SRTM) and initial fields (GFS, ICON-D2, or nearby soundings) areavailable.AlpTherm3d is using heuristic parameterisations for calculating thepixelwise heating or cooling exposed to direct and diffuse irradiationincluding albedo, longwave radiation, evaporation, and ground heat flux.After each time step of 10 minutes, Lagrangian pockets of air are movingeither katabatically or anabatically, forming individual thermals whenleaving the surface. As a last step, the mass balance is re-established.All these non-standard procedures will be discussed during the seminar,with an example for Trentino.Bio2019-now: Finishing and continuing a few activities, such as AlpTherm3d2006-2017: Teaching and research at the Zurich University of AppliedSciences https://www.zhaw.ch/en/engineering/ in aviation meteorology andenvironmental science1990-2019: Airborne research in the same field plus GHG withwww.metair.ch [1]1981-1995: Assistant and Postdoc in several research projects onmesoscale meteorology (e.g. ALPEX and MAP) and atmospheric chemistry,with an emphasis on photosmog.1974-2000: Active glider pilot and instructor, mainly in the AlpsMaster (1980) and PhD (1988) at the Laboratory for Atmospheric Physicsat ETH, after studying Physics.
