| Term: | Refreezing |
| Definition: |
The freezing of meltwater generated at the glacier surface, or of rain, that percolates to some depth at which the temperature is below the freezing point. Refreezing below the summer surface represents internal accumulation. Percolating water may also refreeze at the base of snow overlying impermeable glacier ice, in which case it is called superimposed ice. See zone. The release of latent heat heats the layer within which the water freezes. IHPGlacierMassBalance
