"Stochastic models, an effective tool for simulating atmospheric
dispersion and mixing"

Thursday 3 June 2021 - h15:00 (UTC+2)  - Zoom

This series of lectures is a new joint initiative between the Earth
System Physics group at ICTP and the Atmospherics Physics group at the
University of Trento, and this talk is hosted by Trento.

Abstract
Turbulence in the atmosphere is typically described as random and
unpredictable and requires statistical approaches. In this spirit many
processes driven by turbulence can be successfully and efficiently
modelled using stochastic approaches. Similarly, but in a wider sense,
sub-grid scale dispersion and mixing processes that are not explicitly
resolved by atmospheric flow simulations can be often modelled by using
stochastic approaches for the considered spatial and temporal scales. I
will discuss the formulation and application of simple stochastic models
for the simulation of processes related to atmospheric dispersion of
gases and particles, with spatial scales ranging from few meters (from
an emitting local scalar source) to global.


Bio
Massimo Cassiani was awarded a PhD in Environmental Sciences from
University of Urbino, Italy, in 2002, where he afterward spent some
years as a teacher and researcher. He moved to Duke University (Durham,
NC, USA) in 2005 and to NILU (Norwegian Institute of Air research,
Kjeller, Norway) in 2008. At NILU he also joined the team of scientists
developing the widely used Lagrangian stochastic model FLEXPART. His
research interests deal with turbulence and dispersion in the atmosphere
with application to air pollution and ecological modelling,
boundary-layer meteorology and land-atmosphere interaction. He has
experience in the development of mathematical models but he is also
interested in experimental field measurements of turbulence and
turbulent dispersion. He is currently a member of the editorial board of
the journal Boundary-Layer Meteorology
