Accretion is a term used when an ice crystal or snowflake in the atmosphere hits a supercooled liquid droplet, which then freeze wholly or partially together. A common example of this is graupel.

It is also used to describe the accumulation of ice on objects such as power lines and lift lines by a similar process. This type of ice is usually described by the term rime.
