icing

From Glossary of Meteorology
  1. In general, any deposit or coating of ice on an object, caused by the impingement and freezing of liquid (usually supercooled) hydrometeors; to be distinguished from hoarfrost in that the latter results from the deposition of water vapor.

The two basic types of icing are rime and glaze.
See aircraft icing, carburetor icing.

  1. [Also known as flood icing, flooding ice, aufeis (German), naled (Russian).] A mass or sheet of ice formed during the winter by successive freezing of sheets of water that may seep from the ground, from a river, or from a spring.
