| 3 | Comparison of Cloud Properties between Cloud Sat Retrievals and Airplane Measurements in Mixed-Phase Cloud Layers of Weak Convective and Stratus Clouds显示文摘Cloud microphysical properties including liquid and ice particle number concentration(NC),liquid water content(LWC),ice water content(IWC) and effective radius(RE) were retrieved from Cloud Sat data for a weakly convective and a widespread stratus cloud. Within the mixed-phase cloud layers,liquid-phase fractions needed to be assumed in the data retrieval process,and one existing linear(p1) and two exponential(p2and p3) functions,which estimate the liquid-phase fraction as a function of subfreezing temperature(from-20?C to 0?C),were tested. The retrieved NC,LWC,IWC and RE using p1 were on average larger than airplane measurements in the same cloud layer. Function p2 performed better than p1 or p3in retrieving the NCs of cloud droplets in the convective cloud,while function p1 performed better in the stratus cloud. Function p3 performed better in LWC estimation in both convective and stratus clouds. The REs of cloud droplets calculated using the retrieved cloud droplet NC and LWC were closer to the values of in situ observations than those retrieved directly using the p1 function. The retrieved NCs of ice particles in both convective and stratus clouds,on the assumption of liquid-phase fraction during the retrieval of liquid droplet NCs,were closer to those of airplane observations than on the assumption of function p1. | QIU Yujun Thomas CHOULARTON Jonathan CROSIER Zixia LIU | 2015 | Advances in Atmospheric Sciences2015,32,12: | 1 |
| 4 | A highly immunogenic live-attenuated vaccine candidate prevents SARS-CoV-2 infection and transmission in hamsters显示文摘The highly pathogenic and readily transmissible SARS-CoV-2 has caused a global coronavirus pandemic,urgently requiring effective countermeasures against its rapid expansion.All available vaccine platforms are being used to generate safe and effective COVID-19 vaccines.Here,we generated a live-attenuated candidate vaccine strain by serial passaging of a SARSCoV-2 clinical isolate in Vero cells. | Xiao-Feng Li Zhen Cui Hang Fan Qi Chen Lei Cao Hong-Ying Qiu Na-Na Zhang Yan-Peng Xu Rong-Rong Zhang Chao Zhou Qing Ye Yong-Qiang Deng Yan Guo Si Qin Kaiyue Fan Lei Wang Zijing Jia Yujun Cui Xiangxi Wang Cheng-Feng Qin | 2022 | The Innovation2022,3,2: | 0 |
| 5 | Developing nonlinear additive tree crown width models based on decomposed competition index and tree variables显示文摘Crown development is closely related to the biomass and growth rate of the tree and its width(CW)is an important covariable in growth and yield models and in forest management.To date,various CW models have been proposed.However,limited studies have explicitly focused on additive and inherent correlation of crown components and total CW as well as the influence of competition on crown radius from the corresponding direction.In this study,two model systems were used,i.e.,aggregation method system(AMS)and disaggregation method system(DMS),to develop crown width additive model systems.For calculating spatially explicit competition index(CI),four neighbor tree selection methods were evaluated.CI was decomposed into four cardinal directions and added into the model systems.Results show that the power model form was more proper for our data to fit CW growth.For each crown radius and total CW,height to the diameter at breast height(HDR)and basal area of trees larger than the subject tree(BAL)significantly contributed to the increase of prediction accuracy.The 3-m fixed radius was optimal among the four neighborhoods selection ways.After adding decomposed competition Hegyi index into model systems AMS and DMS,the prediction accuracy improved.Of the model systems evaluated,AMS based on decomposed CI provided the best performance as well as the inherent correlation and additivity properties.Our study highlighted the importance of decomposed CI in tree CW modelling for additive model systems.This study focused on methodology and could be applied to other species or stands. | Siyu Qiu Peiwen Gao Lei Pan Lai Zhou Ruiting Liang Yujun Sun Yifu Wang | 2023 | Journal of Forestry Research2023,34,5: | 0 |
| 6 | Relationships between Cloud Droplet Spectral Relative Dispersion and Entrainment Rate and Their Impacting Factors显示文摘Cloud microphysical properties are significantly affected by entrainment and mixing processes.However,it is unclear how the entrainment rate affects the relative dispersion of cloud droplet size distribution.Previously,the relationship between relative dispersion and entrainment rate was found to be positive or negative.To reconcile the contrasting relationships,the Explicit Mixing Parcel Model is used to determine the underlying mechanisms.When evaporation is dominated by small droplets,and the entrained environmental air is further saturated during mixing,the relationship is negative.However,when the evaporation of big droplets is dominant,the relationship is positive.Whether or not the cloud condensation nuclei are considered in the entrained environmental air is a key factor as condensation on the entrained condensation nuclei is the main source of small droplets.However,if cloud condensation nuclei are not entrained,the relationship is positive.If cloud condensation nuclei are entrained,the relationship is dependent on many other factors.High values of vertical velocity,relative humidity of environmental air,and liquid water content,and low values of droplet number concentration,are more likely to cause the negative relationship since new saturation is easier to achieve by evaporation of small droplets.Further,the signs of the relationship are not strongly affected by the turbulence dissipation rate,but the higher dissipation rate causes the positive relationship to be more significant for a larger entrainment rate.A conceptual model is proposed to reconcile the contrasting relationships.This work enhances the understanding of relative dispersion and lays a foundation for the quantification of entrainment-mixing mechanisms. | Shi LUO Chunsong LU Yangang LIU Yaohui LI Wenhua GAO Yujun QIU Xiaoqi XU Junjun LI Lei ZHU Yuan WANG Junjie WU Xinlin YANG | 2022 | Advances in Atmospheric Sciences2022,39,12: | 0 |
