Sentences with phrase «of the ablation season»

Ablation triangles are placed in a sequence from regions that first lose their snow cover to regions where snow cover perists for a significant portion of the ablation season.

Mass balance measurements are made on the same date each year in August and again in late September close to the end of the ablation season.
