The change in snow grains as the snowpack becomes wet(snow temperature reaches 0 degrees C) and subsequently refreezes is known as melt-freeze metamorphism. This process usually occurs during late winter and spring when air temperatures are high, solar radiation is high, and cycles of melting and refreezing are common. Melt-freeze crust layers that exist in the freeze part of the cycle can be very strong. 5, record 1, English, - melt%2Dfreeze%20metamorphism
Record number: 1, Textual support number: 2 CONT
Melt-Freeze Metamorphism. When snow is warmed to 0°C (32°F) by rain, solar radiation or warm air, rounded grains develop which are joined into clusters by liquid water ... In the spring, when melt-freeze cycles are repeated daily, the resulting spring snow has a coarse-grained appearance. 6, record 1, English, - melt%2Dfreeze%20metamorphism

La métamorphose de fonte [...] se traduit par l'apparition d'eau liquide au sein du manteau neigeux. Elle est provoquée par une chute de pluie ou un redoux prolongé. Il se forme des agglomérats dits grains ronds («gros sel») qui rendent le manteau neigeux très instable. 3, record 1, French, - m%C3%A9tamorphose%20de%20neige%20humide

A decrease of temperature at the Earth’s surface or within the atmosphere due to a negative radiation balance, i.e. when infrared emission from a particular volume or body is greater than solar and/or infrared absorption by that volume or body. 4, record 2, English, - radiative%20cooling
Record number: 2, Textual support number: 1 CONT
Radiative cooling occurs when the sun is no longer supplying the ground and overlying air with energy derived from solar insolation (e.g., night). Instead, the surface of the Earth now begins to lose energy in the form of longwave radiation which causes the ground and air above it to cool. The clouds that result from this type of cooling take the form of surface fog. 5, record 2, English, - radiative%20cooling
Record number: 2, Textual support number: 2 CONT
radiational cooling. Although it occurs primarily at night, it happens when the earth’s surface suffers a net loss of heat due to outgoing radiation. 6, record 2, English, - radiative%20cooling

Le refroidissement par rayonnement [...] a lieu la nuit. La surface terrestre se refroidit en rayonnant dans l'infrarouge. L'air en surface se refroidit alors par contact avec le sol et atteint la température de condensation : Le nuage se forme en surface sous forme de brouillard (on parle alors de brouillard de rayonnement).

Lorsque ces neiges humides subissent un refroidissement, l'eau liquide présente gèle progressivement, créant de solides liaisons de glace entre les grains ronds avec formation d'agglomérats de plusieurs mm et parfois de croûtes de glace. La neige acquiert alors une excellente cohésion dite de regel. C'est ce que l'on peut observer fréquemment au printemps avec l'alternance des réchauffements diurnes et des refroidissements nocturnes. 1, record 5, French, - coh%C3%A9sion%20de%20regel
