SITUATION CONFUSING BUT WAYOUT CLEAR:CHANGES AND PROSPECT OF NORTHEAST ASIAN SITUATION

Recently,in Northeast Asian situation there have occurred escalation of tension and intensification of antagonism seldom seen before.At the same time,however,there are also explorations and signs of restarting dialogue and cooperation that have stagnated since long ago.Development trends of the situation are confusing to the eye,but reconciliation and cooperation remain the way-out for

Northeast Asian Community Building: What Needs to Be Done?

The aim of the Northeast Asian community building is to create an environment for living together peacefully and for realizing prosperity through cooperation. Economically, a community will integrate regional economies and share great interests for common prosperity. Politically, a community will stabilize the region with trust and cooperation. In terms of security, a community will realize the lasting peace of the region. The three economies of China, Japan, and the ROK account for a vast majority of Northeast Asia＇s regional economy. China and the ROK are two key players in the Northeast Asian community building. China-ROK cooperation will be helpful for China-Japan relations that now appear to be in a difficult situation. Northeast Asian economic cooperation has developed into a multi-layered structure both in institutional and non-institutional ways. In order to build the Northeast Asian community, those three countries must first improve and make three close bilateral relationships. However, Northeast Asian community building should not just include China, Japan, and the ROK. The DPRK, Mongolia, and also Russia should be engaged as early as possible. Northeast Asian community is a vision and also a dream that needs great efforts to be realized by both a good spirit and real actions.

The Impacts of Moisture Transport of East Asian Monsoon on Summer Precipitation in Northeast China

By using the ECMWF reanalysis daily data and daily precipitation data of 80 stations in Northeast China from 1961 to 2002, the impacts of moisture transport of East Asian summer monsoon on the summer precipitation anomaly in Northeast China, and the relationship between the variation of moisture budget and the establishment of East Asian summer monsoon in this region are studied. The results demonstrate that the moisture of summer precipitation in Northeast China mainly originates from subtropical, South China Sea, and South Asia monsoon areas. East China and its near coastal area are the convergent region of the monsoonal moisture currents and the transfer station for the currents continually moving northward. The monsoonal moisture transport, as an important link or bridge, connects the interaction between middle and low latitude systems. In summer half year, there is a moisture sink in Northeast China where the moisture influx is greater than outflux. The advance transport and accumulation of moisture are of special importance to pentad time scale summer precipitation. The onset, retreat, and intensity change of the monsoonal rainy season over Northeast China are mainly signified by the moisture input condition along the southern border of this area. The establishment of East Asian summer monsoon in this area ranges from about 10 July to 20 August and the onset in the west is earlier than that in the east. The latitude that the monsoon can reach is gradually northward from west to east, reaching 50°N within longitude 120°-135°E. In summer, the difference of air mass transport between summers with high and low rainfall mainly lies in whether more air masses originating from lower latitudes move northward through East China and its coastal areas, consequently transporting large amounts of hot and humid air into Northeast China.

2023年麦收期河南省连阴雨的气候特征和可能成因

2023年麦收期河南省出现了罕见的连阴雨天气,降水和阴雨日数异常偏多,分别为自1961年以来的历史第五位和第二位。分析连阴雨的可能气候成因,主要结论如下:(1)造成连阴雨的环流形势为欧亚中高纬度西高东低,乌拉尔山高压脊持续发展并出现阶段性阻塞,东北冷涡活跃,冷空气能持续南下,西太平洋副热带高压(以下简称副高)偏北、偏强且异常偏西,来自副高西北侧边缘的暖湿气流和冷空气在河南省交汇。(2)副高偏强、偏北、偏西是由偏强、偏北、偏大、偏东的南亚高压和偏强、偏北的东亚副热带西风急流(以下简称西风急流)的引导所致,而东南亚对流层中高层的暖中心偏大、偏北和偏东且呈东西向带状分布,使南亚高压形成了上述的特征。暖中心和东北冷涡的共同作用,使东亚中高层的气温梯度增大,进而加强了西风急流。(3)2023年前期的La Ni1a事件有利于麦收期副高偏北,但不利于副高偏强和明显偏西。麦收期由于台风扰动由泰国湾至菲律宾群岛以东的热带西太平洋对流活跃释放的凝结潜热较多,以及麦收期前期的春季和麦收期伊朗高原至青藏高原的地面感热和潜热较强,使暖中心形成了上述的特征,进而决定了南亚高压和副高的特征。(4)2023年麦收期北大西洋海温偏高,以及北大西洋三极子为负位相,导致了乌拉尔山高压脊持续发展并出现阶段性阻塞,麦收期前期的春季和麦收期伏尔加河至贝加尔湖西北侧地面感热和潜热偏强,而下游贝加尔湖东南侧至鄂霍次克海地面感热和潜热偏弱一定程度上导致上述两区域分别出现了大范围的位势高度正距平和负距平。

Impacts of Two Types of Northward Jumps of the East Asian Upper-tropospheric Jet Stream in Midsummer on Rainfall in Eastern China

The East Asian upper-tropospheric jet stream （EAJS） typically jumps north of 45~N in midsummer. These annual northward jumps are mostly classified into two dominant types： the first type corresponds to the enhanced westerly to the north of the EAJS＇s axis （type A）, while the second type is related to the weakened westerly within the EAJS＇s axis （type B）. In this study, the impacts of these two types of northward jumps on rainfall in eastern China are investigated. Our results show that rainfall significantly increases in northern Northeast China and decreases in the Yellow River-Huaihe River valleys, as well as in North China, during the type A jump. As a result of the type B jump, rainfall is enhanced in North China and suppressed in the Yangtze River valley. The changes in rainfall in eastern China during these two types of northward jumps are mainly caused by the northward shifts of the ascending air flow that is directly related to the EAJS. Concurrent with the type A （B） jump, the EAJS-related ascending branch moves from the Yangtze-Huai River valley to northern Northeast （North） China when the EAJS＇s axis jumps from 40~N to 55~N （50~N）. Meanwhile, the type A jump also strengthens the Northeast Asian low in the lower troposphere, leading to more moisture transport to northern Northeast China. The type B jump, however, induces a northwestward extension of the lower-tropospheric western North Pacific subtropical high and more moisture transport to North China.

日本对俄观的形成及其东北亚史意义——以岩仓使团为中心

明治维新初期,日本岩仓使团远赴国外考察之旅是日本世界观转变的分水岭,其中尤以对俄国的认知颠覆最具典型性。江户时代,日本人认为俄国是威胁日本独立的强国,又视俄国为体制改革的楷模。访俄考察后,岩仓使团俄国观变化巨大,对俄国实力重新排序并列为欧美强国末位。在重构东北亚国际关系的纷争中,日本认识到俄国的威胁性不如想象中急迫,内则将“俄国威胁论”用于政治斗争,外则借助其威力奠定19世纪下半叶日本对朝鲜政策的基调。日本对“俄国威胁论”的运用对东北亚国际关系史有着重要影响。

A Study on Water Vapor Transport and Budget of Heavy Rain in Northeast China

The characteristics of moisture transport and budget of widespread heavy rain and local heavy rain events in Northeast China are studied using the NCEP-NCAR reanalysis 6-hourly and daily data and daily precipitation data of 200 stations in Northeast China from 1961-2005. The results demonstrate that during periods with widespread heavy rain in Northeast China, the Asian monsoon is very active and the monsoonal northward moisture transport is strengthened significantly. The widespread heavy rainfall obtains enhanced water vapor supply from large regions where the water vapor mainly originates from the Asian monsoon areas, which include the East Asian subtropical monsoon area, the South China Sea, and the southeast and southwest tropical monsoon regions. There are several branches of monsoonal moisture current converging on East China and its coastal areas, where they are strengthened and then continue northward into Northeast China. Thus, the enhanced northward monsoonal moisture transport is the key to the widespread heavy rain in Northeast China. In contrast, local heavy rainfall in Northeast China derives water vapor from limited areas, transported by the westerlies. Local evaporation also plays an important role in the water vapor supply and local recycling process of moisture. In short, the widespread heavy rains of Northeast China are mainly caused by water vapor advection brought by the Asian monsoon, whereas local heavy rainfall is mainly caused by the convergence of the westerly wind field.

Inter-decadal Analysis on the Intensity of Summer Monsoon in Northeast China

In this paper,the intensity index of East Asian summer monsoon in northeast China was defined objectively by using NCEP/NCAR daily reanalysis data and national precipitation data from 1961 to 2004.In the inter-decadal time scales,the correlations between sea-level pressure field,850 hPa flow field,500 hPa geopotential height,sea surface temperature,Arctic sea ice concentration,a variety of oscillation indexes and intensity index of East Asian summer monsoon in northeast China were analyzed.The analysis showed that the great value area of correlations was consistent between sea-level pressure field,500 hPa geopotential height field and intensity index of East Asian summer monsoon in northeast China in pre-winter or summer,and the correlation was much better in summer than in pre-winter.The correlation was poor between the sea surface temperature and intensity index of East Asian summer monsoon in northeast China,but the correlation was good between the Arctic sea ice concentration and intensity index of East Asian summer monsoon in northeast China.The correlation was better between the NPO index and intensity index of East Asian summer monsoon in northeast China than other indexes.

中国与东北亚国家北极事务合作可行性探究

中、日、韩、俄四国同为《斯匹次卑尔根群岛条约》以及《联合国海洋法公约》缔约国,且同属“北极利益攸关国”以及北极理事会观察成员国。俄罗斯虽为北极国家,但自乌克兰危机的“外溢”使得俄罗斯与西方国家之间战略互信度大幅降低后,俄罗斯的北极开发迫切需要合作伙伴。中、日、韩、俄四国在北极航道开通、资源开采、科研探索、环境保护上具有广泛的合作空间与共同利益。但受地缘政治的影响,以及中美竞争持续的升温,中国与东北亚国家在北极事务上的合作受到限制和挤压。基于此,中国与东北亚国家在北极事务上的合作路径应予优化:一是以低政治领域为首要合作方向。以环境保护、科学考察等低政治领域为抓手,推动四国迅速打破双边合作壁垒,从双边合作向多边合作转型。二是以“冰上丝绸之路”为主要合作载体。“冰上丝绸之路”中北极航道以及北极资源勘探开发等内容与日韩两国北极政策相契合,属于四国共同国家利益交汇处。三是以优势互补化解同质化竞争。中、日、韩要发挥各自在资金、技术、制造、运输等方面的优势,以预防船舶碰撞以及油污泄漏为三国总体合作目标,携手通过“冰上丝绸之路”构建中国与东北亚国家北极能源与运输命运共同体。

人类命运共同体视域下的东北亚经济共同体构建

从实践来看,东北亚各国经济互补,无论是制度合作还是功能合作,都具备一定基础,但总体而言,东北亚地区共同的整体性合作平台缺失。面对全球变局,东北亚亟待在人类命运共同体视域下增进构建“经济共同体”的区域共识,整合并完善既有合作机制,形成区域合力,共同应对外部不利环境的冲击,同时还应依托数字经济等积极因素,激发地区经济发展活力,共同谋求经济复苏与增长。未来基于人类命运共同体视域构建东北亚经济共同体,应该以凝聚“区域共生”理念为基础,通过制度合作、功能合作、地方合作、应急合作的“四重叠加”,打造面向未来的东北亚经济区,具体包括:基于经济链接,凝聚形成东北亚“区域共生”理念;加强“区域意识”,推动东北亚各国的集体认同;深化多层次合作,夯实东北亚经济区建设根基;强化国家发展战略对接,逐步推进东北亚经济区建设。

美国新版“印太战略”下的韩日关系

韩日关系是东北亚地区一组重要的双边关系,且韩国、日本通过“共享”美国这一盟友使两国在战略与安全领域形成了一种特殊联系。冷战后,韩日关系因贸易、历史等原因龃龉不断。双边关系在2018年之后不断螺旋式下降,摩擦与冲突程度远超以往,其走向备受国际社会关注。2022年初,美国拜登政府出台了新版“印太战略”,将盟友视为遏制中国、维护霸权的战略资产,明确将日本与韩国置于构筑美国同盟网络的关键位置,突出美日同盟与美韩同盟在美国新版“印太战略”中的支撑地位,为韩日关系发展注入了新动力。近一年来,韩日关系在美国因素影响下呈现不断向好的新趋势。韩日政权先后更替,客观上为两国关系发展提供了适宜的内部“土壤”。双方相互的战略需求为韩日关系转圜提供了关键前提,但两国间结构性、内生性矛盾仍存。未来,韩日关系战术性缓和概率较大,但战略性和解空间有限。
