| Zusammenfassung |
| Mount Everest region influenced by monsoon-dominated climate system is characterized by
dense distribution of debris-covered glaciers. Very low number of papers has addressed on the
interdisciplinary linkage of hydro-meteorological process and the glacier dynamics in high
elevation areas. Here we present the glacier changes from 1958 to 2011 and the
meteorological observations from 1992 to 2011 with the aim of understanding coupled
climate-glacier dynamics using satellite imagery, historical maps and insitu field
measurements. We developed reconstructed single series for temperature and precipitation
through the monthly quantile mapping and expectation maximization techniques from
the insitu observations in different automatic weather stations located in the Mt.
Everest region. Multi-temporal satellite products and topographic maps were used
for glacier terminus, surface and snowline altitude (SLA) analysis from 1958 to
2011. We observed the continuous shrinkage of glaciers since 1958 to 2011 with
accelerated rate in the recent years. The average terminus retreatment of analyzed 29
glaciers was about 372±37 m (7.0 m a-1) in 1958 to 2011 with retreat rate of
6.1±1.9 m a-1 in 1958-75 and nearly its double in 2008-11. The glacier surface
area had loss of 14.3±5.9 % (0.27 % a-1) from 396.2 km2 to 339.5 km2 in 53
years with the loss by 0.12 %a-1 in 1958-75 to 0.70 % a-1 in recent years. The
