For a droplet of supercooled water to change to ice, it must "learn" to rearrange its molecules into a crystalline structure using a seed particle called an ice nucleus. This serves as a catalyst for the water to crystallize.
Icing weather basics: basics--yes. Same ol' stuff--no. Safely flying in winter's ice requires a lot more than knowing rime vs. clear, and trace vs. moderate. Here's some real depth you can use

The crystal growth radiates outward from this center, which is known as an ice nucleus. The dust particle's likely composition is thought to be a form of clay called kaolinite.

The same aerosol suite (aerosol size distribution, aerosol mass, aerosol composition, CCN) and precipitation sampling systems used in previous CalWater 1 efforts were used in the early start campaign Additionally, aerosol filter collections were made for biological and ice nucleating particle analyses extending across the entire mixed-phase cloud temperature regime, and the first field linkage of the CFDC with an ATOFMS to measure the compositions of aerodynamically separated ice crystals [activated ice nucleus (IN)] from the CFDC [using a pumped counterflow virtual impactor (PCVI)].

In the case of PL, snowflakes that don't melt quite all the way are liquid drops with a potentially active ice nucleus in it.
