This approach provides a more realistic representation of collision–coalescence that occurs between ice and cloud particles of various sizes. The binned approach allows the application of specific collection …
WebOct 7, 2024 · A majority of previous cloud models applied one-dimensional bin microphysics to calculate droplet growth after activation. This treatment neglects the solute effect, which underestimates the condensational growth of the giant seeding particles and consequently alters the subsequent collection process between the giant droplets and the ...
