To examine how initial droplet distribution parameters, specifically mean mass and standard deviation, systematically govern the growth of cloud droplets by collection.
Evaluated the mathematical progression of cloud droplet growth by collision and coalescence starting from single initial size distributions.
Tracked spectral spreading, the emergence time and location of a second distribution peak, and the intermediate minimum between distribution maxima.
The rate of initial distribution broadening correlates systematically with the mean mass and standard deviation of the starting distribution.
The timing and spectral placement of the secondary droplet maximum, as well as the magnitude of the intermediate minimum, are directly dependent on initial distribution statistics.

Implication

Microphysical modeling reveals that cloud droplet spread and bimodal peak formation depend directly on initial mean mass and variance, indicating predictable early stages of rain development.
