With further melting, refreezing, and increased weight from newer snowfall above, the snow reaches a granular recrystallized stage intermediate between flakes and ice known as firn.
随着进一步的融化、再结冰,以及上方新的降雪增加的重量,这些雪变成再次结晶阶段的颗粒状中间物,介于小薄片与冰块之间,被称作万年雪。
Snow and ice emit microwaves, but the signal is different for wet, melting snow than for dry.
雪和冰都放射微波,但潮湿、融化的雪放射的微波信号与未融化的雪不同。
The rate of melting in the Arctic isn't just a function of temperature change; local weather conditions, snow cover and ocean currents can also influence ice loss.
北极冰的融化速度加快只是气温变化的一种后果;当地的天气状况,冰雪覆盖程度和洋流都影响着冰的消融。
