Using a convective scale WRF-GSI system and a re fl ectivity observation operator based on the double-moment microphysics (Thompson) scheme, simulated radar re fl ectivity data are produced and then directly assimilated with EnKF through Observing System Simulation Experiments (OSSEs) for the case of typhoon In-Fa (2021). We examined the ability of the EnKF to simultaneously estimate state variables and conducted sensitivity tests to evaluate the impact of updating different state variables. The results show that updating a full set of analysis variables can help obtain highly precise initial fi elds in the model and improve typhoon forecast skills. Excluding the horizontal wind update will affect the adjustment of the temperature fi eld and the sea level pressure fi eld during the cyclic assimilation process. Updating the variables directly related to the re fl ectivity operator alone could adjust hydrometers well, but the positive impact arising from the assimilation quickly vanishes during the forecast. In addition, this study also includes a quantitative RMSE analysis for each variable during the assimilation cycle and compares the effect of each schemes on different variables.

为评估台风条件下毫米波雷达的探测表现,利用上海2018年和2019年4个台风影响期间的毫米波雷达数据,结合雨滴谱仪、静止卫星、S波段天气雷达等资料,探讨了利用毫米波雷达研究台风外围云系的可能性。结果表明:毫米波雷达探测台风外围区域具有良好的性能,对于云降水结构的垂直探测具有一定应用潜力;在降水强度低于5 mm·h^(-1)时雷达对于云顶高度的探测较为准确;提出一种融化层亮带判别方法,亮带识别结果与探空观测一致。对比毫米波雷达与S波段天气雷达降水强度反演,结果显示利用毫米波雷达衰减特征能够实现降水强度廓线的反演,但需要对存在显著雨滴碰并增长的降水进行识别并订正,可为毫米波雷达探测台风外围云系提供参考依据。

Effects of Antimony Stress on Root Growth,Antimony Accumulation and Physiological Characteristics of Ramie(Boehmeria nivea(L.) Gaudich.)

Agricultural Biotechnology 2023年第1期12卷 8-11,15页

作者： Jiecheng HAN Yaxuan LIU Xingguo ZHAN jingyao luo Fulong YANG Jing ZHOU Guiyuan MENG College of Agriculture and Biotechnology Hunan University of HumanitiesScience and TechnologyLoudi 417000China

[Objectives]This study was conducted to investigate the toxicity of heavy metal antimony(Sb) to ramie(Boehmeria nivea(L.) Gaudich.) and the tolerance response in ramie. [Methods] A pot experiment was conducted to study the effects of Sb stress on root growth and Sb accumulation and transport of the root system of cultivated ramie Zhongzhu No.1, as well as on the physiological characteristics of ramie leaves. [Results] The plant height and root dry weight and volume of Zhongzhu No.1 showed an effect of "promoting at low concentrations and inhibiting at high concentrations" with the increase of Sb concentration, and decreased significantly at the concentration of 4 000 mg/kg, but no obvious toxic growth symptoms were observed. The content of Sb in roots(289.7-508.6 mg/kg) and the root-shoot transfer factor(0.09-0.57) of Zhongzhu No.1 increased with the increase of soil Sb concentration, but the change of Sb bioconcentration factor in roots was opposite, indicating that high concentrations of Sb in soil could promote the absorption of Sb in roots and the transport of Sb to the aboveground part, but the Sb enrichment capacity of roots was relatively reduced with the increase of soil Sb. Sb stress had a certain impact on the physiological characteristics of ramie leaves. With the increase of Sb treatment concentration, MDA, POD and SOD showed a change trend of "first increasing and then decreasing", while CAT gradually increased, indicating that Sb stress caused changes in the physiological characteristics of ramie leaves, thereby affecting plant growth and development. [Conclusions] This study provides a theoretical basis for ecological restoration of ramie in mining areas.
