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.

Environmental Meteorology Seminar – D. MacTaggart

Per la serie di seminari in meteorologia ambientale dell’Università di Trento, giovedì 16 maggio 2024 alle ore 14:30, David MacTaggart, dell’Università di Glasgow, terrà un seminario dal titolo: Modelling turbulence – from terrestrial to space weather.

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
Turbulence remains one of the fundamental problems of classical physics.
It has been much studied in the context of the atmosphere and the
oceans, but its importance also extends into space. In particular, we
cannot ignore the effects of turbulence on space weather, which has
important consequences for space travel, artificial satellites and
transport and communication systems on the Earth. Despite the
differences in environments, there are many similarities between
turbulence modelling in the atmosphere and in space weather. In this
talk, I will give a brief introduction to some modelling approaches,
highlighting their pros and cons. I will also present an example of such
modelling from an application related to space weather.

Bio
Dr MacTaggart is a senior lecturer in applied mathematics at the
University of Glasgow, Scotland. His main research interests lie in
magnetohydrodynamics, with applications to solar physics and space
weather (https://www.maths.gla.ac.uk/~dmactaggart/)

Numerical Modelling of Weather and Climate

Tra il 27 giugno e il 15 luglio si terrà a Trento il corso “Numerical Modelling of Weather and Climate“, offerto nell’ambito dell’honors program “Modelling & Simulation” e della scuola di dottorato del Dipartimento di Ingegneria Civile, Ambientale e Meccanica dell’Università di Trento.

Il corso fornisce un’introduzione alla modellistica meteorologica, climatica e della dispersione in atmosfera partendo dalle leggi fisiche fondamentali, con successivi approfondimenti ed esercitazioni nelle tre diverse applicazioni.

Il programma del corso, di 54 ore complessive, si trova sul sito dell’Università o si può scaricare a questo link. Per avere informazioni sull’accesso al corso è necessario inviare una mail all’indirizzo dicamphd@unitn.it.
