IAP Scientists Conduct Intensive Sounding Measurements of Shallow Cumulus Clouds[Mar 21, 2017]

An intensive radiosonde experiment was performed in the summer of 2014, and the findings published in Advances in Atmospheric Sciences constitute the first report of Shallow cumulus (SCu) observations over this region. Their investigations showed that the cloud base height was far in excess of that over ocean areas and the Southern Great Plains of the United States. Further analysis indicated that the formation and maintenance of SCu was in response to wind shear, subsidence, surface forcing and development of the boundary layer.

Soil Microbes Decrease Allelopathic Effects of Invasive Plants by Degrading Allelochemicals[Mar 21, 2017]

Researchers from Group of Plant Physiological Ecology with Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences conducted a study to evaluate the effects of soil microbes on the allelopathic effects of Ageratina adenophora, a noxious invasive perennial weed and established in SW China. The researchers first conducted a competition experiment using soils collected from six invaded and six non-invaded sites. They used activated carbon to diminish the allelopathic effects of the invasive species.

Scientists Made Progress in the Research of Nonlinear Optical Frequency Conversion Technology[Mar 20, 2017]

Recently, the research group led by ZHU Jianqiang and LIU De'an from Key Laboratory of High Power Laser and Physics, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, made significant progress in the field of nonlinear optical frequency conversion technology. A new class of phase matching methods, termed "voltage tunable phase matching", is proposed and experimentally verified.
