To understand rainfall dynamics, the characterization of convective and stratiform dominance needs a careful investigation. However, it remains a grey area to date. In this paper, the authors have attempted to differentiate between convective and stratiform events based on vertical profiles of a few upper-air meteorological elements, namely, cloud liquid water (CLW), precipitation water (PW), and latent heat (LH). The parameters have been obtained from the data product 2A12 of the Tropical Microwave Imager (TMI) onboard the Tropical Rainfall Measuring satellite (TRMM). The paper presents the demarcation technique between convective and stratiform dominance on surface rainfall without ambiguity
