givre opaque

rime ice

sciences naturelles et appliquées - iate.europa.eu

Les petits grêlons, les basses températures et les faibles concentrations en liquide donnent de la glace opaque à bulles (appelée givre opaque) renfermant de petits cristaux de glace et ayant une densité faible.

Small hailstones, low temperatures and low liquid concentrations lead to bubbly, opaque ice (called rime ice), with small ice crystals and low density.
