\nThe collision-coalescence process is a mechanism of rain formation that is most effective in warm clouds, i.e., clouds where the temperature is above freezing (0\u00b0C) throughout. In these clouds, larger cloud droplets fall and collide with smaller droplets, merging with them (coalescing). As they collect more droplets, they grow larger until they become heavy enough to fall as raindrops. This process does not require ice crystals.

\nThe collision-coalescence process is the primary mechanism for precipitation in warm clouds (not extending beyond the freezing level).
\n<\/section>\n
\nClouds that extend beyond the freezing level often involve the ice crystal process (Bergeron-Findeisen process), where supercooled water droplets evaporate and deposit water vapor onto ice crystals, which then grow and fall as snow or melt into rain. Cirrocumulus clouds are high-altitude ice clouds.
