Strengthening South-South Judicial Cooperation to Promote the Development of Global Human Rights

Judicial cooperation is one of the significant components of South-South cooperation. Furthermore, in the process of South-South cooperation, the establishment of a fair, rational, and transparent new system of international justice must be jointly promoted. The Chinese judicial authorities have made new progress in deepening judicial reforms, enhancing judicial transparency, improving human rights judicial protection mechanisms and strengthening the construction of smart courts, and have accumulated rich judicial experience. Under the background that many changes and great upheavals are taking place in the international world, countries of the Global South should strengthen their judicial exchanges and cooperation, especially in the field of the judicial protection of human rights. SouthSouth cooperation should be enhanced and they should learn from each other, so they can jointly make contributions to the development of the legal world.

Poverty Reduction, Cultural Narrative, and the Realization of Development Rights in South-South Cooperation

The development of any country or society requires a cultural context. A cultural narrative influence the process of development by shaping people’s views and actions, and thus policy. This paper first discusses the importance of cultural narratives, and then analyzes the different cultural narratives on poverty reduction, development, right to development, and South-South Cooperation. It illustrates how cultural narratives significantly influence social justice development and reforms.

The 30–60-day Intraseasonal Variability of Sea Surface Temperature in the South China Sea during May–September

This study investigates the structure and propagation of intraseasonal sea surface temperature（SST） variability in the South China Sea（SCS） on the 30-60-day timescale during boreal summer（May-September）. TRMM-based SST, GODAS oceanic reanalysis and ERA-Interim atmospheric reanalysis datasets from 1998 to 2013 are used to examine quantitatively the atmospheric thermodynamic and oceanic dynamic mechanisms responsible for its formation. Power spectra show that the 30-60-day SST variability is predominant, accounting for 60% of the variance of the 10-90-day variability over most of the SCS. Composite analyses demonstrate that the 30-60-day SST variability is characterized by the alternate occurrence of basin-wide positive and negative SST anomalies in the SCS, with positive（negative） SST anomalies accompanied by anomalous northeasterlies（southwesterlies）. The transition and expansion of SST anomalies are driven by the monsoonal trough-ridge seesaw pattern that migrates northward from the equator to the northern SCS. Quantitative diagnosis of the composite mixed-layer heat budgets shows that, within a strong 30-60-day cycle, the atmospheric thermal forcing is indeed a dominant factor, with the mixed-layer net heat flux（MNHF） contributing around 60% of the total SST tendency, while vertical entrainment contributes more than 30%. However, the entrainment-induced SST tendency is sometimes as large as the MNHF-induced component, implying that ocean processes are sometimes as important as surface fluxes in generating the30-60-day SST variability in the SCS.

Intact Polar and Core Tetraether Lipids in Sediments from the Haiyang 4 Cold-seep of the Northern South China Sea and their Implications

A number of cold seeps have been discovered in the northern South China Sea(SCS) including the Haiyang 4 cold-seep area where Core 973-5 was collected. Intact polar lipids(IPLs) and core lipids(CLs) were analyzed separately in sediments from Core 973-5. The most abundant lipid biomarkers were isoprenoidal GDGTs(iso GDGTs), with Crenarchaeol and GDGT-0 predominating. IPL-iso GDGTs and CL-iso GDGTs were mainly derived from Thaumarchaeota. IPL-iso GDGTs were mainly produced and retained in situ thus containing most of the in situ microbiological information. Branched GDGTs were predominantly derived from generated in marine production, and mixed with some terrestrial inputs. All IPLs groups presented a high value in the sulfate-methane transition zone(SMTZ). Furthermore, IPL and CL-MI, IPL-R;showed the highest values within the SMTZ, while IPL and CL-R;had the lowest values at the SMTZ, suggesting that the contribution of Methanophila and methanogenic to GDGTs increased, while the contribution of ammonia-oxidizing Archaea to GDGTs decreased at the SMTZ.

Differential interformational velocity analysis as an effective direct hydrocarbon indicator under velocity reversal conditions,an example from the anomalously high temperature and over-pressured DF1-1 Gas Field in the Yinggehai Basin,South China Sea

In the DF1-1 Gas Field in the Yinggehai Basin, South China Sea, the velocity-depth plot and velocity spectra show significant variations from a linear trend, exhibiting a distinct reversal phenomenon. Velocity parameters derived from velocity spectral analysis of the seismic data and sonic logs indicate that the interval velocity reverses below 2,100 m (2.2 s two-way time (TWT)) in the DF1-1 Gas Field. Some direct hydrocarbon indicators (DHIs) models developed for the shallow strata cannot be simply applied to the moderately to deeply buried strata for direct exploration target recognition because the velocity reversal has caused the middle-deep gas reservoirs to exhibit a moderate or weak seismic amplitude. The hydrocarbon indicator method of “Differential Interformational Velocity Analysis (DIVA)” with the aid of other hydrocarbon indicating techniques was employed to effectively identify DHIs in the middle-deep strata under velocity inversion. The result has shown that the DIVA technique can be effectively used as a DHI in both the shallow and the middle-deep strata in the study area with the shallow strata characterized by Type I DIVA anomaly and the middle-deep strata characterized by the Type II DIVA anomaly.

COMPARISON STUDY ON THE INTRASEASONAL VARIATIONS IN CIRCULATIONS AND PRECIPITATION MODULATED BY THE TROPICAL CYCLOGENESIS OVER SOUTH CHINA SEA-WESTERN PACIFIC DURING GUANGDONG FLOODING PERIOD

Based on tropical cyclone datasets from Shanghai Typhoon Institute of China Meteorological Administration,the National Centers for Environmental Prediction (NCEP,USA) reanalysis data and the rainfall records from 743 stations in China,the impacts of cyclogenesis number over the South China Sea and the western Pacific are studied on the 30-60-day oscillations in the precipitation of Guangdong during the flooding period.The year with more-than-normal (less-than-normal) tropical cyclogenesis is defined as a 'high year' ('low year').In light of the irregular periodic oscillations,the method used to construct the composite life cycle is based on nine consecutive phases in each of the cycles.Phases 1,3,5,and 7 correspond to,respectively,the time when precipitation anomalies reach theminimum,a positive transition (negative-turning-to-positive) phase,the maximum,and a negative transition phase.The results showed that the precipitation of the 30-60-day oscillations is associated with the interaction between a well-organized eastward propagation system from the Arabian Sea/Bay of Bengal and a westward-propagating system (with cyclonic and anticyclonic anomalies in the northwest-southeast direction) from the South China Sea to western Pacific during the high years,whereas the precipitation is affected during a low year by the circulation over the South China Sea and western Pacific (with cyclonic and anticyclonic anomalies in the northeast-southwest direction).During the high year,the warm and wet air mass from the ocean to the west and south are transported to Guangdong by westerly anomalies and an enclosed latitudinal cell,which ascends in the Northern Hemisphere low latitudes and descends in the Southern Hemisphere low latitudes.During the low year,the warm and wet air mass from the ocean to the south is transported to Guangdong by southwesterly wind anomalies and local ascending movements.Because the kinetic energy,westerly,easterly shift,vertical velocity and vapor transportation averaged over (109-119° E,10-20° N) is stronger in high years than those in low years,the precipitation of the 30-60-day oscillations in Guangdong is higher in high years than that in low years.

康布麻曲“5.28”山地灾害致灾雨情的天-地协同调查

2021年5月28日,位于喜马拉雅山南坡的西藏自治区亚东县康布麻曲流域暴发暴雨山洪灾害,地处流域下游的沿河战备公路出现多处崩塌与河岸坍塌,部分路段严重受损,电力、通信、交通运输中断,威胁下游军民生命安全,严重影响居民生活和军备物资正常供给。通过实地调查,明确了灾情险情,并联合卫星遥感和地面雨量监测数据研判了致灾降雨过程。结果表明:持续降雨和短时强降雨的叠加作用是山洪、边坡崩塌(含落石)、河岸坍塌等灾害发生的主要诱发因素;崩塌等局部性山地灾害与站点监测雨量变化有密切关系;卫星监测显示,下司马镇西侧为主要的暴雨中心,局部区域5月25~28日的持续降雨以及26和28日的两次短历时暴雨过程,激发了山洪及山地灾害。值得特别注意的是,此次灾害的发生时间并非主汛期,现场调查表明部分河岸和边坡仍存在垮塌的可能,应尽快加固边坡和河堤。总体来看,站点监测雨量更倾向于解释崩塌等局部性山地灾害,而卫星监测则易于判识区域性山洪形成的主要源区,协同两种监测手段则可能有利于流域山地灾害全方位多尺度的监控与应急响应。

Stratigraphical Time——Correlation and Mass Extinction Event Near Permian——Triassic Boundary in South China

Shaw's method used to correlate 40 sections across the Permo-Triassic boundary in South China is applied in the paper. Two steps are adopted to get an Integral Composite Section (ICS) by synthesizing these data : First , South China is divided into five areas and composite section developed for each area . Then the second step . the Changxing composite section is regarded as a composite standard (CSRS) while the ICS is produced by matching the CSRS with composite sections of the other areas. Three biozones in the Changxingian and two biozones in the Griesbachian can be discerned on the basis of computing Z values in the ICS. These biozones are marked by the Z values which quantitatively represent their time ranges ; therefore , they may increase accuracy of stratigraphic time correlation . The mass extinction at the end of the Permian is an abrupt event that is supported by the relative rate of extinction near the P/T boundary . About 90% of invertebrate species died out by the end of the Permian . The duration of the mass extinction is rather short ,approximately 0.018Ma .

Zircon U–Pb dating of Pubei granite and strontium isotope from sphalerite of the Xinhua Pb–Zn–(Ag) deposit,Yunkai Area of Guangxi Province,South China

The Yunkai Area is located at the southern South China Block and is part of the Qinzhou Bay-Hangzhou Bay Metallogenic Belt, which is a famous polymetallic mineralization belt. The Xinhua Pb–Zn–(Ag)deposit is located in the western part of Yunkai Area, with an abundance of Pubei batholiths. Zircon U–Pb geochronology of Pubei batholiths shows that crystallization age ranges from 251.9 ± 2.2 to 244.3 ± 1.8 Ma, thus belonging to Indosinian orogeny. Geochemistry and Sr isotopic compositions of the Pubei batholiths show that it is derived from the partial melting of large scale crustal melting during the stage of exhumation and uplifting of the lower-middle crust. In addition, strontium isotope of sphalerite from the Xinhua Pb–Zn–(Ag) deposit, has limited ranges in ^(87)Rb/^(86)Sr and ^(87)Sr/^(86)Sr, ranging from 0.4077 to 1.0449, and 0.718720 to 0.725245, respectively. The initial ^(87)Sr/^(86)Sr ratios of sphalerite ranges between 0.718720 and 0.725245, which is higher than that of upper continental crust and lower than that of the Pubei batholiths, illustrating the fluid might be derived from the mixing of Pubei pluton and upper continental crust.

RELATIONSHIP BETWEEN THE 30 TO 60 DAY OSCILLATION OF ATMOSPHERIC HEAT SOURCE AND THE DROUGHT AND FLOOD EVENTS IN JUNE IN THE SOUTH OF CHINA

Based on the NCEP/NCAR reanalysis data and the observed precipitation data in the south of China from 1958 to 2000,the impact of 30 to 60 day oscillation of atmospheric heat sources on the drought and flood events in June in the south of China is discussed.During the flood(drought) events,there exists an anomalous low-frequency anticyclone(cyclone) at the low level of the troposphere over the South China Sea and the northwestern Pacific,accompanied with anomalous low-frequency heat sinks(heat sources),while there exists an anomalous low-frequency cyclone(anticyclone) with anomalous heat sources(sinks) over the area from the south of China to the south of Japan.On average,the phase evolution of the low-frequency in drought events is 7 to 11 days ahead of that in flood events in May to June in the south of China.In flood events,low-frequency heat sources and cyclones are propagated northward from the southern South China Sea,northwestward from the warm pool of the western Pacific and westward from the northwestern Pacific around 140°E,which have very important impact on the abundant rainfall in June in the south of China.However,in drought events,the northward propagations of the low-frequency heat sources and cyclones from the South China Sea and its vicinity are rather late compared with those in flood events,and there is no obvious westward propagation of the heat sources from the northwestern Pacific.The timing of the low-frequency heat source propagation has remarkable impact on the June rainfall in the south of China.

Origins of intraseasonal rainfall variations over the southern South China Sea in boreal winter

This study investigates the origins of intraseasonal rainfall variations over the southern South China Sea（SCS） region in boreal winter.It is found that intraseasonal rainfall variations over the southern SCS have different origins on the 10-20-day and 30-60-day time scales.On the 10-20-day time scale,large rainfall anomalies over the southern SCS are preceded by strong northerly wind anomalies associated with the East Asian winter monsoon（EAWM）,by about two days.On the 30-60-day time scale,the strong EAWM-related northerly wind anomalies almost appear simultaneously with large rainfall anomalies over the southern SCS.In addition,obvious large rainfall anomalies occur over the southeastern tropical Indian Ocean about one week before the peak southern SCS rainfall anomalies.It indicates that the convection and related circulation anomalies with origins over the tropical Indian Ocean may play an important role in inducing intraseasonal rainfall variations over the southern SCS on the 30-60-day time scale,but not on the 10-20-day time scale.

Global Climate Change and Emerging Environmental and Strategic Security Issues for South Asia

Global climate change-essentially an adverse consequence of global warming, is principally caused by progressive build-up and extensive spread of greenhouse gases (GHGs) across countries, regions or continents because of earth’s rotational movement. The potent sources of GHGs are fossil-fuels and biomass. With the increasing pace of globalization, industrialization and rapid change of life-style the demand and consumption of these feed-stocks to stimulate economic growth is steadily rising-both in the developing and developed economy. In the process, the emissions level is also rising phenomenally;and of late become quite alarming-more in the former than latter case, affecting thereby the environmental quality as also its security concerns globally. This paper highlights the major impacts of global warming and consequential climate change on the environmental quality and overall security aspects-including commercial, strategic and defense angles for the South-Asian region. The paper also discusses some relevant aspects linking the larger question of energy security with environmental security through the approach of sustainable energy development for envisioning a balanced economic development as well as growth perspective for South Asia. The significance of International cooperation in the mitigation and adaptation of climate change impacts with special reference to Asia- Pacific and South Asian region is also discussed at some length in the paper.

Belt and Road Initiative and Possible Impacts on the SouthChina Sea Issue

Since China proposed the Belt and Road Initiative （BRI） in late 2013, the impacts of the 21st century Maritime Silk Road （MSR） construction on the South China Sea （SCS） issue become a focal point of both academic research and public concern. There are plenty of divergent opinions on whether the MSR will mean an opportunity for settling the SCS issue, or it will face the challenge of intensified maritime conflicts in this region. This paper first of all analyzes the significance of the BRI in the general picture of China＇s foreign policy. To ensure neighborhood diplomacy be in line with the BRI, China adjusts its SCS policy through rebuilding and consolidating political mutual trust with countries which have been involved into conflicts with China on the SCS issue; meanwhile, China promotes pragmatic cooperation under MSR framework to cultivate positive atmosphere and sense of community with a shared destiny. Both MSR construction and the addressing of the SCS issue are long-term issues, while the MSR provides an innovative approach to surpass existing disputes and focus on regional development cooperation. Hence, the MSR could be an opportunity to accelerate the resolving of maritime disputes.
