Tommaso Alberti

I am a researcher at the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Rome, Italy. My research has an inter-disciplinary character and it mainly focuses on the understanding of processes occurring in geosciences, space sciences, and complex systems at different spatio-temporal scales. My investigations revolve around several key areas as weather and climate extremes with impacts on aviation turbulence, airports closures due to the adverse weather conditions, Acqua Alta events in Venice, flooding events after huge storms; turbulence and dissipation in both fluids and plasmas; and tipping points to develop statistical methods for identifying transition thresholds in complex systems at bifurcation points at different spatio-temporal scales with application to climate and paleoclimate, turbulence, and epidemiology.

#shareEGU20: Networking event of the NP Division

The current COVID-19 situation has profoundly changed our daily lifes and has also affected our way to perform and share research. In today’s world a lot of efforts have been made to minimize the impact of working from home and exchange thoughts with colleagues, and also the usual annual General Assembly of the European Geosciences Union (EGU) has been moved online. Thus, the largest online ...[Read More]

NP Division at the General Assembly 2020

Each year the European Geosciences Union organizes the largest European geosciences event which is the EGU General Assembly. It usually attracts over than 15000 scientists from all over the world, including both established researchers and early career scientists, who contribute to more than a half of the participants. It consists of several sessions (usually more than 500), covering a wide spectr ...[Read More]

NPG Paper of the Month: “Unravelling the spatial diversity of Indian precipitation teleconnections via a non-linear multi-scale approach”

Schematic map of spatial diversity of Indian precipitation teleconnections at different time scales. (a) ENSO, (b) IOD, (c) NAO, (d PDO, and (e) AMO. Colors are consistent with the Indian community shown in the right figure. Presence of color in community segment indicates significant synchronization between teleconnection and Indian precipitation. Every single segment of circle shows the temporal scale. Cardinal direction has been projected in the background of each circle.

Today’s we launch one of our promised activities: the NPG Paper of the Month. This month the award is achieved by Jürgen Kurths and co-authors for their paper “Unravelling the spatial diversity of Indian precipitation teleconnections via a non-linear multi-scale approach” (https://www.nonlin-processes-geophys.net/26/251/2019/). Ankit Agarwal, one of the authors of the manuscript, tells ...[Read More]
