Climate forcing of physical and electrical properties of snow covered sea ice

第一年(FYI)海冰上的积雪是海洋冰冻圈的关键组成部分，因为由于其相对较小的导热系数，它控制着冰的积累和消融速度。在春夏过渡期间，雪起到隔离海冰与大气变暖的作用，最终调节冬季海冰厚度和夏季融化行为，并在很大程度上决定其机械强度，最终控制海冰夏季解体潜力。例如，如果海冰在冬季生长，积雪较薄，则冰层厚度将被最小化。因此，这种薄薄的积雪更有可能在春天更早地融化，从而使融化的水淹没冰面，降低反射率，吸收更多的太阳辐射，导致更早的海冰消融。

The snow cover on first-year (FYI) sea ice is a critical component of the marine cryosphere because it controls ice accretion and ablation rates due to its relatively small thermal conductivity. The snow acts to insulate the sea ice from the warming atmosphere during the spring to summer transition and ultimately regulates winter sea ice thickness and summer melt behavior, and largely determines its mechanical strength which ultimately controls sea ice summer break-up potential.. For example, if the sea ice grows in winter with a thin snow cover, the ice thickness will be minimized. This thin snow cover is then more likely to melt earlier in spring, thereby flooding the ice surface with melt water, lowering the reflectivity and absorbing more solar radiation, leading to earlier sea ice ablation.
