Supercooled Water
•Ice melts at 0°C, but water does not necessary freeze to ice at 0°C.
•Ice nuclei is needed
to help water to get frozen.
•Certain microscopic particles, such as clay, organic particles, or bacteria, have a crystalline structure similar to ice
that can allow water
molecular to attach to and to build an ice lattice.
•Without enough ice nuclei, water can exist event its temperature is below between 0°C and -40°C, which are called
“supercooled water”.
•Supercooled water can result in freezing precipitation when they come in contact with a surface that has a temperature
below 0°C.
