Impacts of Coastal SST Variability on the East Asian Summer Monsoon

The impacts of the seasonal and interannual SST variability in the East Asia coastal regions （EACRSST） on the East Asian summer monsoon （EASM） have been examined using a regional climate model （PδRCM9） in this paper. The simulation results show that the correlation between the EACRSST and the EASM is strengthened after the mid-1970s and also the variability of the EACRSST forcing becomes much more important to the EASM interannual variability after the mid-1970s. The impacts of the EACRSST on the summer precipitation over each sub-region in the EASM region become weak gradually from south to north, and the temporal evolution features of the summer precipitation differences over North and Northeast China agree well with those of the index of EASM （IEASM） differences.
The mechanism analyses show that different EACRSST forcings result in the differences of sensible and latent heat flux exchanges at the air-sea interface, which alter the heating rate of the atmosphere. The heating rate differences induce low level air temperature differences over East Asia, resulting in the differences of the land-sea thermal contrast （LSTC） which lead to 850 hPa geopotential height changes. When the 850 hPa geopotential height increases over the East Asian continent and decreases over the coast of East China and the adjacent oceans during the weakening period of weakens consequently. On the contrary, the EASM enhances during the strengthening period of the LSTC.     

济南东部埠村超单元及其就位机制

分布于济南东部六山圈—大有一带的侵入岩,为燕山早期同一岩浆热事件多次侵入形成的杂岩体,依其形成顺序可划分为山张庄、西杜、大有、赵家鹊山四个单元,归并为埠村超单元。该超单元的形成与幔源基性岩浆上侵及同源岩浆分异产生的中偏基性—中性岩浆多次侵入有关,属热气球式膨胀与火山口塌陷复合就位机制。     

对山东高压-超高压变质带的几点看法——程裕淇院士野外考察记

通过对山东高压超高压变质带的考察,初步认为：榴辉岩的最后隆升时代为燕山期;含硬玉石英岩＋榴辉岩＋（透辉石）大理岩组合说明表壳岩经历了高压超高压变质作用;该带晋宁期长英质片麻岩花岗岩广泛出露;在其北部麻粒岩和榴辉岩密切伴生。     

Asian Labor Recruitment and the World Wide Web

International labor migration is produced and patterned through the activities of government and private institutions, such as labor recruiters and government officials. Recently, labor recruitment agencies have utilized the World Wide Web as a means of facilitating the procurement of foreign employment contracts. The purpose of this research is to examine the institutional usage of the Web as a means to facilitate the global flow of labor. Based on a qualitative assessment of 27 recruitment-related Web sites, I suggest that Web-based recruitment reinforces global patterns of gendered, racial, and occupational segregation. Moreover, Web-based recruitment offers the potential for revolutionizing patterns and processes of international labor migration.     

柴达木盆地东缘晚更新世气候变化的（古）土壤发生记录

柴达木盆地东缘典型剖面（古）土壤及其黄土线质的宏观特征和理化分析表明,本区晚更新世以来气候曾有几次较大的波动,反映了全球冰量影响的气候波动以及东亚季风气候的强弱变化特征。揭示出气候变化过程中温度和降水并不同步,温度主要受地球轨道变化引起的太阳辐射的影响;降水则主要取决于冬、夏季风的浊弱对比关系,夏季风盛行时,降水丰沛。间冰段古土壤Ｓｍ的土壤发生特征和强度,揭示了除低温引起的蒸发减少外,降水丰沛也是     

Metallogenic focus-area and superlarge mineral deposits in the bordering zones between China,Russia and Mongolia

Two deep-sea cores in the northwest Pacific have been analysed for sedimentology, mineralogy and environmental magnetism. The results show that after eliminating the interference from volcanism, several proxies such as quartz content, mass susceptibility and anhysteretic magnetic remanence can be used to indicate the eolian deposit from East Asia, and provide information on paleo-atmospheric circulation. A comparison of eolian record in Cure RC10-175 with its oxygen isotopic curve has revealed that the peaks of eolian accumulation occurred at the climatic “optimum” of the Holocene and the last interglaciation, showing the fairly complex nonlinear relationship between continental/pelagic eolian records and the global glacial cycles as well as within the climatic and environmental system.

Resource-based development in the Russian Far East: Problems and prospects

The paper examines the prospects for resource-based development in the Russian Far East. It adopts a critical perspective on the potential for resource-based development by examining problems with Far East resource industries, specifically by looking at the experience of the other resource economies more generally. In particular, it highlights the new geo-economic context for resource development in the Far East of Russia as the world economy approaches the much touted, and now questioned, ‘Pacific Century’.     

Cretaceous transgressions and regressions on the Russian Platform, in Crimea and Central Asia

This paper is a brief explanation of the diagrams of the Cretaceous transgressions and regressions on the Russian Platform, in the Crimea (Figures 1–3) and some regions of central Asia—the western flanks of the Tien Shan mountains, the Fergana basin, the Zeravshan-Gissar and Alaj mountains, and the Northern Pamirs (Figures 5–7).Internationally recognized stages are employed. They are interpreted by Sasonova (1967) for the Lower Cretaceous (K₁) of the Russian Platform, by Naidin (1977) for the Upper Cretaceous (K₂) of the Platform and the Crimea, by Djalilov (1971) and Pojarkova (1976) for the Upper Cretaceous of central Asia. General data on the stratigraphy of the Cretaceous of central Asia may be found in Anon 1977.     

准四年周期的北半球夏季遥相关与东亚夏季风环流的相互关系

利用ＮＭＣ的２００ｈＰａ和８５０ｈＰａ风场资料研究了北半球夏季遥相关和东亚夏季风异常环流在准４年时间尺度上的相互关系。研究发现当北半球夏季出现积雪强迫型遥相关时,东亚－西太平洋地区既存在异常纬向环流,也存在异常经向环流;而当出现东亚太平洋型遥相关时,东亚－西太平洋地区以异常纬向环流为主。分析还发现源于北太平洋的异常涡旋在向南传播的过程中,先取西南路径,在到达菲律宾东部以后折向东南。
