The 2021 Nobel Prize was awarded in part to Syukuro Manabe and Klaus Hasselman for the physical modelling of Earth’s climate. In this talk I will discuss the 1964 paper of Manabe and Strickler on “Thermal Equilibrium of the Atmosphere with a Convective Adjustment” but I will try to put it into a modern context and overview present understanding of physics of climate change.  I will begin with observations. The concept of Earth Energy Imbalance (EEI) will be introduced and its measurements including GRACE satellite mission and ARGO floats will be discussed.  Next, I will move to the theoretical aspects of the climate change problem. I will begin with a description of Global Circulation Models, 4D Var data assimilation, weather reanalysis. Next, I will touch on physics of 1-dimensional stick models which are used to parameterize physical processes in Global Climate Models. I will finalize with comments on climate research and observational challenges including k-scale modeling and future climate observational systems.

This is an online event.
