NP Campfire: “Scaling and multifractals : from historical perspectives to recent developments”

Scaling law behaviours are ubiquitous in geosciences both from a theoretical and practical point of view. They are required to better understand, analyse and simulate the underlying processes, which yields the observed variability of geophysical fields over wide ranges of spatio-temporal scales.
A group of scientists within the Nonlinear Processes in Geosciences (NP) Division of the European Geosciences Union (EGU) is launching in the campfire framework a series of webinars on “Scaling and multifractals: from historical perspectives to recent developments.”

The aim of the campfire is to hear first-hand from internationally recognized experts of the field their personal perspectives on scaling and multifractals. They will share their thoughts on the historical background of the field as well as its recent developments and future goals. This unique opportunity, targeted to both early career scientists and established researchers, aims at fostering discussions within the research community to push it toward pursuing past achievements.

To register, send an email to with subject subscribe egu_np_campfire_multifractals.
Registration is free but mandatory. Link to connect will be sent shortly before the webinar.

Tommaso Alberti (INAF-IAPS, Italy)
Yongxiang Huang (Xiamen University, China)

I am a researcher at the Institute for Space Astrophysics and Planetology, an Institute within INAF (National Institute for Astrophysics), in Rome, Italy. My work focuses on nonlinear dynamical system approaches and data analysis in geosciences with particular interests in solar wind – magnetosphere – ionosphere interactions and coupling, space and near-Earth plasma turbulence, and Earth’s climate dynamics. I am the Early Career Scientists Representative for the Nonlinear Processes in Geosciences (NP) Division.
