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.The article

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
