Eva: Energy and mass balance modelling for glaciers on the
Tibetan Plateau; Aachen, Techn. Hochsch., Diss., 2014},
abstract = {The Tibetan Plateau is the source region of five of the
largest Asian rivers. The large amount of ice, snow and
permafrost on the plateau and its surrounding mountain
ranges and the stored water therein is important in
sustaining seasonal water availability. According to the
overall trend of increasing air temperatures on the Tibetan
Plateau and its adjacent areas since several decades, most
glaciers are retreating. The regional patterns of glacier
change are contrasting, influenced by local factors and the
spatial and temporal heterogeneity of climate and climate
variability. The individual feedback mechanisms between
atmosphere and glacier, and the role of the various
components of the glacier surface energy and mass balance in
the melt process for different climate regions on the
Tibetan Plateau have not yet been analysed in detail. This
thesis deals with the modelling of glacier surface energy
and mass balances on the Tibetan Plateau. Four glaciers and
one ice cap on the plateau and its surrounding mountain
ranges form the regional study sites: Zhadang glacier (south
eastern Tibetan Plateau), Purogangri ice cap (central
plateau), Naimona’nyi glacier (western Himalayas), Halji
glacier (western Himalayas) and Muztag Ata glacier (eastern
Pamirs). The study sites have a maximum distance of
approximately equal 1700 km from each other and are located
in different climate regions. As it is the case for most
remote regions of the world, data availability from in-situ
observations is insufficient for more complex,
physically-based glacier energy and mass balance models.
Hence, we use the in-situ measurement data from the
intensive observation period at Zhadang glacier to evaluate
the surface energy and mass balance model performance in
detail. For decadal model simulations high resolution
atmospheric model data from the High Asia Reanalysis is
applied. The model scheme couples the atmospheric energy
balance to a subsurface multi-layer snow module in order to
analyse the atmosphere-cryosphere interactions. For Zhadang
glacier the different model components are thoroughly
validated using different methods and data sources. The
installed complex monitoring system including a time-lapse
camera system at Zhadang glacier is the first of its kind on
the Tibetan Plateau. It provides an excellent data base for
model evaluation and provides new opportunities for further
analysis. The developed surface energy and mass balance
model is applied to the five study sites. From every
regional study we obtain a 10-year time series of
glacier-wide surface energy and mass balance components. At
each study site model results are compared to either in-situ
meteorological or glaciological data or remote sensing
analyses which provide evidence for further constraints
regarding the tuning parameters of the modelling chain. This
is the largest and most detailed homogeneous glaciological
data set from the Tibetan Plateau so far regarding the
modelling of surface energy and mass balance. The thesis
contributes to a further and detailed understanding of the
role of the various energy and mass balance components for
glacier change in the different climate regions of the
Tibetan Plateau. It serves to increase knowledge on the
various driving mechanisms for the energy and mass balance
components. The findings are crucial for estimating future
glacier evolution. It forms the basis for further analysis
and research on glacier related water availability on the
Tibetan Plateau.},
