Tommaso Alberti

I am a postdoctoral 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 time series 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.

The newly elected NP Division President François Schmitt.

Today’s NP Interviews hosts the newly elected NP Division President François Schmitt. François has a PhD degree from Université Pierre et Marie Curie in Paris (1993), in atmospheric turbulence, and an Habilitation degree from the same university (2001). He has stayed in Belgium during 6 years as a post-doc, working in meteorology and in fluid mechanics. He is CNRS researcher in Wimereux (Nor ...[Read More]

NPG Paper of the Month: “On fluctuating momentum-exchange in idealised models of air-sea interaction”
Probability density function of the energy (normalized so that the average is unity for each variable) lost by the atmosphere and gained by the ocean at t=300 and averaging time τ=0, atmosphere full-line, ocean dashed-line, and for averaging time τ=100, atmosphere dotted-line, ocean dashed-dotted-line. All are clearly non-Gaussian. (Source: A. Wirth, On fluctuating momentum exchange in idealised models of air–sea interaction, Nonlin.

This month the NPG Paper of the Month award is achieved by Achim Wirth for his paper “On fluctuating momentum-exchange in idealised models of air-sea interaction” (https://www.nonlin-processes-geophys.net/26/457/2019/). Achim tells us about the importance of the results achieved with this paper for investigating the energy coupling between the ocean and the atmosphere. Achim obtained his PhD at th ...[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]

Today’s NP Interviews hosts the Lewis Fry Richardson Medallist Shaun Lovejoy. Shaun has degrees in physics from Cambridge and McGill University; he has been a McGill professor since 1985. For four decades, he has developed fractal, scaling ideas in the geosciences, contributing to advances in cascade processes, multifractals, anisotropic scale invariance, space-time multifractal modeling as well a ...[Read More]
