Numerical modelling of planetary processes
The laboratory on Numerical Modeling of Planetary Processes at the Institute of Geosciences and Earth Resources deals with the study of some of the main geological, geomorphological, fluid dynamical and climatic processes of the Earth System and of other planets or satellites.
The aim of the laboratory is to understand, through computer simulations and the analysis and interpretation of both observational data and modelling results, some of the processes that determine the dynamics at the surface (ocean, atmosphere, continental surfaces) and in the interior of rocky planets, their climate and paleoclimate. Particular attention is devoted to the interactions between geosphere and biosphere in the Earth System and to the analysis of the conditions that can allow the presence of life on rocky planets (or satellites).
The approach is based on the use of deterministic conceptual models, empirical data-driven models and global climate models. The sustainability of the laboratory is based on funding from national and international research projects.
Laboratory activities are based on the development, implementation and use of deterministic numerical models, both conceptual and complex, and on the use of community models. Currently, we use ESTM models (evolutions of EBM), box models for soil-vegetation-atmosphere interaction, simplified models of ecosystems, models for turbulent rotating convection, quasi-geostrophic turbulence models, the JULES model, the EMIC PLASIM model and the coastal Delft3D model. Data-based, empirical models are developed and used to estimate and predict the response of specific systems (fires, glaciers, ecosystems) to climate variability.
For numerical simulation using conceptual models, we use the workstations and the multi-processor servers available at CNR. The heaviest simulations are currently carried out at CINECA.

The laboratory is based on the development, implementation and use of deterministic numerical models, both conceptual and complex. Currently, ESTM models (evolution of an EBM), box models for soil-vegetation-atmosphere interaction, simplified models of lake ecosystems, the JULES model and the EMIC PLASIM model are used.
Data-based, empirical models are also developed and used to estimate and predict the response of specific systems (fires, glaciers, ecosystems) to climate variability.
Currently, the activities of the laboratory are devoted to the following research topics:
Planetary fluid dynamics
- Turbulent rotating convection, in water and in fluids with high Prandtl number, as a conceptual basis for the simulation of the convective dynamics in planetary atmospheres and oceans, in oceans covered by a thick ice layer (Ganymede, Europa) and in the mantle of rocky planets.
- Vortex dynamics in planetary atmospheres and oceans, with particular reference to the dynamics of the atmospheres of gaseous planets (Jupiter).
- Estimates of the habitability of rocky planets using simplified climate models (EBM, ESTM, EMIC).
- Dynamics of aeolian ripples and megaripples in sandy desert regions of Earth and Mars.
- Empirical and deterministic modeling of the response of Alpine glaciers to climate change.
- Coastal processes and modelling of coastal erosion.
Geosphere-biosphere-climate interactions in the Earth System
- Dynamics of soil-vegetation-atmosphere interactions in the "Critical Zone" in extreme environments, with special focus on mountain regions and the Arctic tundra.
- Dynamics of mountain lake ecosystems and interactions between lake ecosystems, environment and climate.
- Empirical modeling of the relationships between climate, vegetation and fires through "data-based" models for the estimation and prediction of the burned area.
