Mid-latitude westerlies as a driver of glacier variability in monsoonal High Asia

09.12.2013
New publication by TU Berlin climatologists details previously unknown connection

Climatologists at TU Berlin discovered a previously unknown connection between glacier variability and temperate zones. In their new publication, Dr. Thomas Mölg, Fabien Maussion and Prof. Dr. Dieter Scherer show that westerlies in Europe play a part in influencing the Asian glaciers on the Tibetan Plateau. Their findings have just been published in “Nature Climate Change“.

Glaciers in High Asia store large amounts of water and are affected by climate change. Efforts to determine decadal-scale glacier change are there-fore increasing, predicated on the concept that glaciers outside the northwest of the mountain system are controlled by the tropical monsoon. Here we show that the mass balance of Zhadang Glacier on the southern Tibetan Plateau, 2001-2011, was driven by midlatitude climate as well, on the basis of high-altitude measurements and combined atmospheric-glacier modelling.

Results reveal that precipitation conditions in May-June largely determine the annual mass-balance, but they are shaped by both the intensity of Indian summer monsoon onset and mid-latitude dynamics. In particular, large-scale westerly waves control the tropospheric flow strength over the Tibetan Plateau remotely.

This strength alone explains 73% of interannual mass-balance variability of Zhadang Glacier, and affects May-June precipitation and summer air temperatures in many parts of High Asia’s zone of monsoon influence. Thus, mid-latitude climate should be considered as a possible driver of past and future glacier changes in this zone.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
