The authors examine the spatial and temporal characteristics of the simulated Pacific Decadal Oscillation （PDO） in 109 historical （i.e. all forcings） simulations derived from 2. coupled models within CMIPS. Compared with observations, most simulations successfully simulate the observed PDO pattern and its teleconnections to the SSTs in the tropical and southern Pacific. BNU-ESM, CanESM2. CCSM4, CESM 1 -FASTCHEM, FGOALS-g2. GFDL CM3. MIROCS, and NorESM 1 -M show better performance. Compared with the temporal phases of the observed PDO in the twentieth century, only five simulations -- from CNRM^CMS, CSIRO Mk3.6.0, HadCM3. and IPSL-CMSA-LR -- simulate an evolution of the PDO similar to that derived from observation, which suggests that current coupled models can barely reproduce the observed phase shifting of the PDO. To capture characteristics of the observed PDO in the twentieth century, a requirement is that all the relevant external forcings are included in the models. How to add realistic oceanic initial states into the model may be another key point.

大气是挥发性和半挥发性污染物迁移扩散的重要介质,也是污染物进入人体的主要途径,因此,大气中污染物的环境行为的研究具有重要的意义.本研究通过采集雪样和降雪后连续2. h内的大气样品,对16种多环芳烃(PAHs)进行了分析,对降雪后大气中PAHs的变化规律进行了深入研究.结果表明,16种PAHs在降雪中的检出率为100%,菲的浓度最高(53..3.g·L^(-1)),其次是萘(509.1 ng·L^(-1))和荧蒽(42..9 ng·L^(-1)),说明降雪能够对大气中的PAHs进行去除.降雪后大气中PAHs的浓度呈现下降-上升-下降的变化规律,高浓度出现在汽车尾气排放量最大的上下班期间,低浓度则出现在人类活动少的时间段,说明人类活动是大气中PAHs浓度变化的主要影响因素.降雪后2. h内大气中PAHs在气相和颗粒相间的比值变化较小,其组成主要受PAHs的物理化学性质的影响.特征分子比值法表明,降雪后2. h内大气中PAHs主要来源于固体燃料燃烧源和液体燃料的燃烧源.

In recent decades, the typical E1 Nifio events with the warmest SSTs in the tropical eastern Pacific have become less common, and a different of E1 Nifio with the wannest SSTs in the central the east and west by cooler Pacific, which is flanked on SSTs, has become more frequent. The more recent type of E1 Nifio was referred to as central Pacific E1 Nifio, warm pool E1 Nifio, or dateline E1 Nifio, or the E1 Nifio Modoki. Central Pacific E1 Nifio links to a different tropical-to-extratropical teleconnection and exerts different impacts on climate, and several clas- sification approaches have been proposed. In this study, a new classification approach is proposed, which is based on the linear combination （sum or difference） of the two leading Empirical Orthogonal Functions （EOFs） of tropi- cal Pacific Ocean sea surface temperature anomaly （SSTA）, and the typical E1 Nifio index （TENI） and the central E1 Nifio index （CENI） are able to be derived by projecting the observed SSTA onto these combinations. This classification not only reflects the characteristics of non-orthogonality between the two types of events but also yields one period peaking at approximate two to seven years. In particular, this classification can distin- guish the different impacts of the two types of events on rainfall in the following summer in East China. The typi- cal E1 Nifio events tend to induce intensified rainfall in the Yangtze River valley, whereas the central Pacific El Nifio tends to induce intensified rainfall in the Huaihe River valley. Thus, the present approach may be appropriate for studying the impact of different types of E1 Nifio on the East Asian climate.

Air quality in eastern China has becoming more and more worrying in recent years, and haze is now No.1 air pollution issue. Results in this study show the decreasing Arctic sea ice(ASI) is an important contributor to the recent increased haze days in eastern China. The authors find that the number of winter haze days(WHD) in eastern China is strongly negatively correlated with the preceding autumn ASI during 1979–2.12. and about 45%– 67% of the WHD interannual to interdecadal variability can be explained by ASI variability. Following previous studies on the impact of ASI loss on the northern hemisphere climate, the authors' studies further reveal that the reduction of autumn ASI leads to positive sea-level pressure anomalies in mid-latitude Eurasia, northward shift of track of cyclone activity in China, and weak Rossby wave activity in eastern China south of 40N during winter season. These atmospheric circulation changes favor less cyclone activity and more stable atmosphere in eastern China, leading to more haze days there. Furthermore, the patterns of circulation changes associated with autumn ASI and WHD are in very good agreement over the East Asia, particularly in eastern China. The authors suggest that haze pollution may continue to be a serious issue in the near future as the decline of ASI continues under global warming.

利用区域数值模式WRF-ARW(V3.9)开展高分辨率数值模拟试验,研究了东北地区大兴安岭和长白山地形对该地区夏季降水的单独和共同影响。结果表明,东北地区两大山脉地形可以显著影响东北及其周边区域的大气环流和降水。大兴安岭和长白山地形的阻挡作用使得夏季偏南气流在两个山脉的迎风坡一侧堆积,引起局地水汽增加并产生上升运动,因此两个山脉的迎风坡一侧降水增加;而在两个山脉的背风坡一侧,局地水汽减少并伴随下沉运动,因此两个山脉的背风坡一侧降水减少。大兴安岭地形的存在使得其东侧到松嫩平原地区夏季降水增加1.09 mm d^-1(相较参照试验增幅为3.%),而使其西侧蒙古东部地区夏季降水减少0.69 mm d^-1(相较参照试验减幅为2.%);长白山地形的存在使得长白山南侧到朝鲜半岛地区夏季降水增加1.76 mm d^-1(相较参照试验增幅为2.%),而使其北侧三江平原地区夏季降水减少0.81 mm d^-1(相较参照试验减幅为2.%)。当大兴安岭与长白山同时存在时,两者的协同作用会减弱蒙古东部、松嫩平原和朝鲜半岛地区夏季降水的响应,而增强三江平原地区夏季降水的响应。该研究结果对于理解东北地区当代气候的形成具有重要的科学意义。

This study documents the decadal changes of the spring meridional circulation （SMC） over 110°E- 165°E and the relationship between the SMC and summer （June-July-August-September） typhoon activity over the Western North Pacific （WNP） during 1948-2.10. The authors found that the SMC was changed after 1969. Before its change, the SMC had no clear relation with the summer typhoon number over the WNP （TNWNP）, but after the change, it has become positively correlated with the TNWNP, with a correlation coefficient of 0.57 be- tween them （above the 99% confidence level）. It was ob- served that after the SMC was changed, the positive tropical sea surface temperature anomaly associated with the SMC was shifted from the Equatorial Eastern Pacific （El Nifio） to the equatorial middle Pacific （El Nifio Mo- doki）; at the same time, the Pacific decadal oscillation （PDO） pattern over the North Pacific, which is associated with the SMC, was enhanced. The SMC and the TNWNP are both modulated by the E1 Nifio Modoki after 1969, so the relationship between them becomes significant.
