Short summary

We simulated the glacier evolutions in Bhutanese Himalaya during the LIA using OGGM. At the regional scale, four compelling glacial substages were reported, and a positive correlation between the number of glacial substages and the glacier slope was found. Based on the surface mass balance analysis, the study also indicated that the regional glacier advances are dominated by the reduction of summer ablation.
