Ablation (meteorology)
In meteorology, ablation is the melting and sublimation of snow and ice , often used primarily for the loss of mass in glaciers .
The ablation gradient is used to describe the extent to which a glacier loses mass with increasing altitude. The ablation gradient in m water column per 100 m height difference indicates the amount by which the annual melting decreases with 100 m increase in height.
The amount of melted water (of a glacier) in grams per cubic centimeter or in cm of water column is called the ablation volume . The ablation volume during the day is related to that at night as 23:18.
The ablation period is the period within a year in which the melting of snow and ice can take place.
The so-called penitentiary ice or penitentiary snow can be used as an example of a characteristic form of ablation . It is a snow surface, which consists of a field of pointed pillars that point in the direction of the strongest solar radiation.
