The El Ni?o-Southern Oscillation cycle simulated by the climate system model of Chinese Academy of Sciences

On the basis of more than 200-year control run, the performance of the climate system model of Chinese Academy of Sciences （CAS-ESM-C） in simulating the E1 Nifio-Southern Oscillation （ENSO） cycle is evalu- ated, including the onset, development and decay of the ENSO. It is shown that, the model can reasonably simulate the annual cycle and interannual variability of sea surface temperature （SST） in the tropical Pacif- ic, as well as the seasonal phase-locking of the ENSO. The model also captures two prerequisites for the E1 Nino onset, i.e., a westerly anomaly and a warm SST anomaly in the equatorial western Pacific. Owing to too strong forcing from an extratropical meridional wind, however, the westerly anomaly in this region is largely overestimated. Moreover, the simulated thermocline is much shallower with a weaker slope. As a result, the warm SST anomaly from the western Pacific propagates eastward more quickly, leading to a faster develop- ment of an E1 Nino. During the decay stage, owing to a stronger E1Nino in the model, the secondary Gill-type response of the tropical atmosphere to the eastern Pacific warming is much stronger, thereby resulting in a persistent easterly anomaly in the western Pacific. Meanwhile, a cold anomaly in the warm pool appears as a result of a lifted thermocline via Ekman pumping. Finally, an E1 Nino decays into a La Nina through their interactions. In addition, the shorter period and larger amplitude of the ENSO in the model can be attribut- ed to a shallower thermocline in the equatorial Pacific, which speeds up the zonal redistribution of a heat content in the upper ocean.

Developing institutional repositories network:Taking IR Grid at Chinese Academy of Sciences as an example

This paper introduces the current practice of building a network of institutional repositories(IRs) at Chinese Academy of Sciences(CAS), which is named CAS IR Grid.National Science Library(NSL) of CAS plays a leading role in the construction, promotion and implementation of CAS IR Grid. It aims to promote each institute of CAS to build IR of its own, and finally form the IR network of CAS institutes. NSL's experience is introduced in coordinating and supporting institutes' building of their respective IRs and promoting IR services by adopting collaborative and progressive development strategies. Achievements made during the development of CAS IR Grid are described and challenges for its future development are discussed. The authors aim to provide best practices for developing a network of institutional repositories in research institute settings, which can serve as a practical reference to other institutions engaged in the similar task.

Significant Breakthrough in Industrial Test of the "Methanol to Olefins" Process Developed by Dalian Institute of Chemical Physics,Chinese Academy of Sciences

A process of ＂Methanol or Dimethylether to Olefins＂ developed by Dalian Institute of Chemical Physics （DICP）, designated as the DMTO process, has attained great success in industrial scaling up testing. DICP, by collaborating with the Xinxing Coal Chemical Co., Ltd. of Shaanxi Province and the Luoyang Petrochemical Engineering Co. of the SINOPEC Group, operated successfully a 50t（methanol）/d unit for the conversion of methanol to lower olefins, with a methanol conversion of close to 100%, and a selectivity to lower olefins（ethylene, propylene and butylenes） of higher than 90%. On 23rd August, the industrial test project has passed a state appraisal. The experts of the Appraisal Group, headed by Prof. YUAN Qingtang, academician of Chinese Academy of Engineering, drew the conclusions that the DMTO process, by utilizing a proprietary SAPO-34 catalyst system and a recycling fluidized bed reaction system for the production of lower olefins from methanol, is the first unit in the world having a capacity of producing nearly ten thousand tons lower olefins per year. The technological level of the industrial test is at a leading position internationally. This accomplishment will provide a sound base for the subsequent commercialization of the DMTO process.

Yunnan snub-nosed monkey research of the Kunming Institute of Zoology, Chinese Academy of Sciences

At the beginning of 2016, I returned to the Baima Snow Mountain with a CC＇I-V film crew. As the birth place of the Yunnan snub-nosed monkey, Baima Snow Mountain in northwest Yunnan belongs to the transition zone between the Qinghai-Tibet and Yunnan-Guizhou plateaus, and is regarded as the most magnificent of the Yunling Mountains. Revisiting my old haunt, I cannot help but recall the international snub-nosed monkey research launched by the Kunming Institute of Zoology （KIZ） so many years ago.
