Valerio Lembo

Research Activity


I am interested in various aspects of climate dynamics, mainly those affected by and affecting energy budgets and transports, and the interaction between heat and momentum. I develop methods to diagnose the thermodynamics and the general circulation of the atmosphere, as a way to contribute bringing the basic principles of physics into the climate modeling debate. I use methods from statistical mechanics and dynamical systems theory to explore the response of the climate system to external forcings, the role of internal variability and long-term predictability.
