The role of warm clouds in monsoon rainfall and the onset of the warm-rain process are investigated using quality-controlled, high-resolution cloud-sensitive radar measurements consisting of 1.8 million profiles during July–August 2015. Radar reflectivity profile can infer the vertical structure of clouds in identifying warm clouds. In the cloud droplet-to-raindrop transition, an intense spike in the spectral width (SW) indicates turbulence which triggers the growth of cloud droplets through the collision-coalescence process to form the raindrops. This study provides a multi-observation-based perspective on the macro- and micro-physical characteristics of monsoon warm clouds and the onset of warm rain for verification with theory /DNS and a better representation in the models.
