The IAMAS-CNC Early Career Scientists Nobel Prize Online Interpretation Workshop

1.Overview The 2021 Nobel Prize for Physics was awarded to three scientists for their contribution to the physical understanding of complex systems(The Nobel Committee for Physics,2021).Two of the laureates,Dr.Syukuro MANABE and Dr.Klaus HASSELMANN,are climate scientists.This is the first time a climate scientist has won a Nobel Prize for physics and is thus a great encouragement to the entire climate science community,especially young scientists.Because the two winners'groundbreaking contributions that led to their award were achieved decades ago,young people may not be very familiar with these works.Therefore,to help young scientists better understand the scientific merit of the fundamental works and to inspire them in their future research careers,on 20 October 2021,the young scientist working group of The China National Committee of the International Association of Meteorology and Atmospheric Sciences(IAMAS-CNC)organized an online Nobel Prize interpretation workshop.Over 400 participants attended the online workshop,and more than 120000 parti-cipants watched the replay.     

Numerical Modeling on Suspended Sediment Transportation in the Hangzhou Bay

In this paper the characteristics of tidal flow and seasonal variation of seidment content in theHangzhou Bay and their affecting factors are studied.Field investigations and data analysis indicate thatthe sediment movement is mainly influenced by the Yangtze estuary and the sediment of the Yangtze estua-ry is induced by wind wave and tidal flow.Owing to the variation of dynamic conditions,the instanta-neous sediment content is controlled by tidal flow,wind wave,depth of water and tidal range synthetically.A sediment content relationship formula is established with related factors.A non-equilibrium2-dimensional numerical model of suspended sediment transportation is set up,and the finite element meth-od is applied.The computation results of the model is in accordance with field data.     

螺旋藻多糖对CD3AK细胞增殖能力的影响

研究了螺旋藻多糖（ＰＳ）对ＣＤ３ＭｃＡｂ激活的杀伤细胞（ＣＤ３ＭｃＡｂ Ａｃｔｉｖａｔｅｄ Ｋｉｌｌｅｒ Ｃｅｌｌｓ,ＣＤ３ＡＫ Ｃｅｌｌｓ）增殖能力的影响。结果表明,当ＰＳ浓度为２．５μｇ·ｍｌ＾－１培养体系条件下,对ＣＤ３ＡＫ细胞具有明显的刺激细胞增殖作用（Ｐ〈０．０２）;对培养长达２３ｄ的ＣＤ３ＡＫ细胞杀伤肿瘤细胞（Ｋ５６２细胞）的活性仍维持在较高的水平（４６．５％￣５０％）。提示ＰＳ对辐射

东南极格罗夫山地区夏季的天气特征

利用中国南极科学考察队 1 998年 1 2月至 1 999年 1月在东南极格罗夫山地区地质考察期间所获得的天气资料 ,对该地区的温度、雪面温度、风速、风向等天气要素进行了分析。结果表明 :夏季格罗夫地区温度日变化和盛行风向与中山站相类似 ,但温度日较差和强风频率比中山站大。当受来自北方暖湿气流影响时 ,常出现降雪天气 ;在东风气流控制下 ,天气以晴为主     

华北克拉通北缘柴胡栏子金矿富甲烷流体包裹体的发现及地质意义

柴胡栏子金矿位于华北克拉通北缘赤峰-朝阳金矿集区西段,是区内典型的石英脉型为主的金矿床,也是赤峰-朝阳地区首次发现的含大量单相甲烷包裹体群的金矿床.矿体呈脉状产于太古宙建平群大营子组下岩段含石墨绢云母片岩切层断裂中,金主要产出在蚀变含石墨绢云母片岩和石英脉中.根据野外观察和包裹体测温结果,将柴胡栏子金矿流体成矿过程划分...     

锆石氧逸度对义敦岛弧南段中甸矿集区斑岩型矿床差异性成矿控制因素的指示

中甸铜钼多金属矿集区位于义敦岛弧南段,区内绝大多数矿床与晚三叠世和晚白垩世岩浆活动有关,目前两期斑岩锆石氧逸度及差异性成矿研究薄弱.对4个斑岩体5类岩石的锆石开展LA-ICPMS微量元素分析,数据经筛选检验后进行了氧逸度估算.氧逸度结果由高到低为:地苏嘎铜矿晚三叠世石英闪长玢岩(Ce4+/Ce3+比值为515)、休瓦促...
