Summary

Observations of cloud droplet spectra in various kinds of clouds have shown that the microstructure of clouds very largely determines the efficiency of the coalescence process in forming rain. They have also suggested that the observed differences in microstructure must be primarily explained by differences in the spectra of cloud nuclei in different air masses. This hypothesis has now been confirmed by simultaneous observations of the spectra of cloud nuclei and cloud droplets.
