1. Overview The upper troposphere-lower stratosphere （UTlS） of the Asian summer monsoon （ASM） region is characterized by a continental-scale anticyclonic circulation, which is dynami- cally active and coupled to monsoonal convection. The monsoon anticyclone exhibits anomalous chemical and aerosol characteristics, linked to the outflow of deep convection and the large-scale circulation, and strongly influences the global UTlS composition during boreal summer.

应用2013年8月SWOP（sounding water vapour,ozone,and particle）观测计划在拉萨获得的臭氧和水汽廓线资料,分析臭氧和水汽的相关关系,发现近一半的观测资料在上对流层–下平流层区域出现异常。应用Cla MS（the Chemical lagrangian Model of the Stratosphere Model）轨迹模式,计算探空廓线的20天后向轨迹来分析相关异常。模拟结果表明发生在西太平洋的3个热带气旋（Jebi、Utor和Trami）可以输送边界层低臭氧浓度空气到夏季亚洲季风（ASM）反气旋对流层上部,进而对臭氧和水汽产生影响。边界层空气通过台风强垂直输送作用到达对流层顶附近后,进入到ASM反气旋内部拉萨测站通过两条输送路径,一是快速直接水平输送,二是沿着反气旋运动一周的缓慢长距离输送。同时,ASM反气旋和热带气旋的空间相对位置关系决定了空气块的输送路径。近一个月的观测数据表明,台风的影响作用主要发生在拉萨测站上空14.5–17 km/365–370 K高度附近。

雷公藤乡甙(GTW)在雄性大鼠及男子均可致不育而无明显毒副作用,从雷公藤提得的新化合物T_4在雄大鼠也有明确的抗生育作用,至于它们是否会产生遗传学后果,是人们关注而迄未报道的问题。本文进行了GTW对大鼠及人某些重要遗传学指标的影响,包括大鼠显性致死突变、胎肝淋巴细胞染色体畸变与微核率、以及人外周淋巴细胞染色体畸变率、姐妹染色单体互换(SCE)率、微核率、细胞分裂指数的研究,也观察了T_4对大鼠外周淋巴细胞微核率的影响。结果表明,从上述指标来看,抗生育剂量的GTW及T_4未见导致明显的遗传学影响。

A high-resolution dual-band terahertz(THz) radiometer was designed to measure vertical distributions of chemical elements in the middle atmosphere of the Tibetan Plateau. A forward simulation, which always should be conducted firstly for the development of a matching retrieval algorithm, has not been done before. We use two radiative transfer models, ARTS and AM, to simulate the water vapor, ozone and carbon monoxide spectra on the plateau based on the spectral design of the THz radiometer. The emission line characteristics of the three gases in this spectral band are identified. Reasons for the differences in the spectral simulations between the two models are analyzed for individual gases. The impact of several different spectral parameter settings on the simulations are evaluated through a series of sensitivity experiments. This study suggests that the ARTS is more suitable for the development of the THz radiometer retrieval algorithm. An optimal parameter setting of the ARTS for the three elements are given.

In the paper, we propose a new method of identifying the clear sky based on the Atmospheric Emitted Radiance Interferometer （AERI）. Using the Atmospheric Radiation Measurement （ARM） Mobile Facility （AFM） dataset in Shouxian in 2008, we sim- ulate the downwelling radiances on the surface in the 8-12 μm window region using line-By-line Radiative Transfer Model （lBlRTM）, and compare the results with the AERI radiances, The differences larger （smaller） than 3 mW （cm2 sr cm-1）-1 suggest a cloudy （clear） sky. Meanwhile, we develop the new algorithms for retrieving the zenith equivalent cloud base height （CBHe） and the equivalent emissivity （ee）, respectively. The retrieval methods are described as follows. （1） An infinitely thin and isothermal blackbody cloud is simulated by the lBlRTM. The cloud base height （H） is adjusted iteratively to satisfy the situation that the contribution of the blackbody to the downwelling radiance is equal to that of realistic cloud. The final H is considered as CBHe. The retrieval results indicate that the differences between the CBHe and observational cloud base height （CBH） are much smaller for thick low cloud, and increase with the increasing CBH. （2） An infinitely thin and isothermal gray body cloud is simulated by the lBlRTM, with the CBH specified as the observed value. The cloud base emissivity （co） is ad- justed iteratively until the contribution of the gray body to the downwelling radiance is the same as that of realistic cloud. The corresponding εc is εe. The average εe for the low, middle, and high cloud is 0.967, 0.781, and 0.616 for the 50 cases, respec- tively. It decreases with the increasing CBH. The retrieval results will be useful for studying the role of cloud in the radiation budget in the window region and cloud parameterizations in the climate model.
