俄乌冲突延宕影响深远

Contemporary International Relations 2024年第1期34卷 23-28页

作者： cicir Task Force Chen Yu 不详 the institute of eurasian studies at cicir

In 2023, the Ukraine crisis entered its second year. Neither side made concessions. The United States and the West continued to aid Ukraine. The crisis may be difficult to end in the short term. At the same time, the impact of the Ukraine crisis continues to expand, with profound implications for the international landscape, international security, and the global economy.

国际安全形势更趋严峻

Contemporary International Relations 2024年第1期34卷 17-22页

作者：陈庆鸿巩小豪刘冲 the institute of International Security studies(IISS)at cicir the IISS at cicir the IISS CICIR

The year 2023 was a year of international conflict: the international security environment deteriorated, the risk of war increased, war taboos were broken, and new forms of war emerged. As major countries transition to engage in actual combat and war preparation, the risk of conflict and regional instability among major countries has risen markedly.

To harness the rich solar energy resources in Xinjiang Region of Northwest China,this study tries to address the issue of lack of downward surface shortwave radiation(DSSR)observations and the need to improve the accuracy of satellite retrieval and numerical simulation of DSSR under varied sky and meteorological conditions.(1)A two-layer aerosol model specific to Xinjiang was developed to capture the vertical distributions of aerosols based on multiple data sources including lidar,GPS sounding,ground meteorological observations,and profiles from the ECMWF reanalysis version 5(ERA5)*** results show that the ERA5/PBLH(planetary boundary layer height)and ERA5/ALH(aerosol layer height)could be used to establish the two-layer aerosol model and characterize the vertical distribution of aerosols in Xinjiang Region.(2)Using the Santa Barbara Discrete Atmospheric Radiative Transfer(SBDART)model,a localized inverse model of clear-sky DSSR was *** parameter adjustment and using the optimal combination of input parameters for DSSR simulation together with the two-layer aerosol model,the model-simulated DSSR(DSSRSBD)under clear-sky conditions improved significantly compared to the initial results,with all fitting indices greatly improved.(3)In addition,the study demonstrated that the impact of the two-layer aerosol model on DSSR was more pronounced under dust conditions than clear-sky conditions.(4)Using the localized clear-sky DSSR inversion model and its required parameters,simulations were also conducted to capture the spatiotemporal distribution of DSSR under clear-sky conditions in Xinjiang from 2017 to *** annual average DSSR_(SBD)under clear-sky conditions in Xinjiang during 2017–2019 was 606.78 W m^(-2),while DSSR from CERES(DSSR_(CER))under the same conditions was generally higher(703.95 W m^(-2)).(5)It is found that satellite remote sensing products experienced data loss in high-altitude snow areas,where numerical simulation technology could ser
