Short summary
A thermodynamic parcel analysis of several high-resolution soundings from Pune, India, investigating pre-monsoon and monsoon conditions, is carried out in this study. A simple theoretical approach for cloud base height estimation is illustrated. Results illustrate the role of surface forcing in contrasting conditions of the pre-monsoon and monsoon. Large eddy simulations, observational data, and theoretical explanation are presented.
