Abstract

A review on those ice cliffs, which are mostly associated with dry calving events, is presented. The focus is on the persistent, rarely-calving ice cliffs on the plateau glaciers of Kibo, the main peak of the Kilimanjaro massif, Tanzania. Modelling solar irradiance, in conjunction with on-site measurements, revealed that direct insolation is the reason for (1) the predominant zonal alignment of the ice cliffs and (2) their bimodal annual recession. The former peculiarity occurs because near the equator steep north- and south-facing slopes receive only little solar energy, which prevents strong ablation. The bimodal recession pattern is caused by the particular annual path of the sun in the tropics
