Abstract

Following a quick overview of the research activities in atmospheric physics being conducted by the Atmospheric Physics Group at the University of Bologna, this presentation will focus on a selection of recent topics that have yielded interesting results through the integration of observational and modelling tools.

The first topic will be the study of the structure of a supercell storm, which has been conducted using a comprehensive range of instruments, including GEO VIS-IR and LEO PMW sensors, ground-based and space-borne radar, lightning network and reanalysis. These observations were used to develop a new modeling tool based on the Large Eddy Simulation approach. The objective was to reproduce some of the well-known and lesser-known features that contribute to the unique characteristics of a supercell storm.

The second topic is also challenging because it concerns the estimation of precipitation at high latitudes, particularly over Antarctica, which is characterized by low ice content and a variety of hydrometeor shape and size. In this case, the synergy used is between disdrometer, radar, and radiative transfer modeling output, with the aim of improving the radar precipitation rate estimate after the adaptation of the relationship between snowfall rate and reflectivity.
