| active site |
A site on an ice nucleus that forms ice at a lower supersaturation or a smaller supercooling than elsewhere, resulting from a local impurity or defect giving a region of local strain and deformation in the atomic arrangement of the nucleus, matching it more closely to the arrangement of molecules in ice, and a lower energy requirement for nucleation.
