Formation of water droplets is also critical. Like ice formation, the transition of water vapor to the liquid phase (condensation) can be mediated by catalysts. These catalysts are called "Cloud Condensation Nuclei" (CCN). Although the properties of CCN are rather different from those of ice nuclei (IN) (CCN are often soluble materials whereas IN are insoluble), micro-organisms can be CCN as well as IN. The ...
