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:

Abstract
AlpTherm is a tool for assessing convection for air sports, with a first
operational version dating back to 1993. I will therefore outline the
historical background and the special motivation for this applied
science.
AlpTherm3d is fully three-dimensional, using a high resolution for the
orography, and is adaptable to any region where digital terrain data
(e.g. SRTM) and initial fields (GFS, ICON-D2, or nearby soundings) are
available.
AlpTherm3d is using heuristic parameterisations for calculating the
pixelwise heating or cooling exposed to direct and diffuse irradiation
including albedo, longwave radiation, evaporation, and ground heat flux.
After each time step of 10 minutes, Lagrangian pockets of air are moving
either katabatically or anabatically, forming individual thermals when
leaving 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.
