The Indian summer monsoon is a dramatic multiscale, multiphysics event that has a profound impact on the food security of more than a billion people. Predictions for the monsoon rainfall using present-day general circulation models are often wide of the mark, with serious consequences for the economy of the countries of the Indian subcontinent. An understanding of the basic dynamical features of the monsoon system is an important open problem.
In this talk, I will try to review "my" current understanding (to be distinguished from "our" current understanding) of the salient features of the dynamics of the monsoon. I will also present some of the past attempts at modelling some features of the monsoon using simple models. In particular, I will discuss the PDE models related to the work of Gill (doi:10.1002/qj.49710644905) and ODE models related to the work of Zickfeld et al. (doi:10.1029/2005GL022771). This is an ongoing work in collaboration with Raj Saha, Rama Govindarajan, Vishal Vasan, SajiniAnand, Vijay Prakash.
