| 1 | Prediction of Primary Climate Variability Modes at the Beijing Climate Center显示文摘Climate variability modes, usually known as primary climate phenomena, are well recognized as the most important predictability sources in subseasonal–interannual climate prediction. This paper begins by reviewing the research and development carried out, and the recent progress made, at the Beijing Climate Center(BCC) in predicting some primary climate variability modes. These include the El Ni?o–Southern Oscillation(ENSO), Madden–Julian Oscillation(MJO), and Arctic Oscillation(AO), on global scales, as well as the sea surface temperature(SST) modes in the Indian Ocean and North Atlantic, western Pacific subtropical high(WPSH), and the East Asian winter and summer monsoons(EAWM and EASM, respectively), on regional scales. Based on its latest climate and statistical models, the BCC has established a climate phenomenon prediction system(CPPS) and completed a hindcast experiment for the period 1991–2014. The performance of the CPPS in predicting such climate variability modes is systematically evaluated. The results show that skillful predictions have been made for ENSO, MJO, the Indian Ocean basin mode, the WPSH, and partly for the EASM, whereas less skillful predictions were made for the Indian Ocean Dipole(IOD) and North Atlantic SST Tripole, and no clear skill at all for the AO, subtropical IOD, and EAWM. Improvements in the prediction of these climate variability modes with low skill need to be achieved by improving the BCC's climate models, developing physically based statistical models as well as correction methods for model predictions.Some of the monitoring/prediction products of the BCC-CPPS are also introduced in this paper. | Hong-Li REN Fei-Fei JIN Lianchun SONG Bo LU Ben TIAN Jinqing ZUO Ying LIU Jie WU Chongbo ZHAO Yu NIE Peiqun ZHANG Jin BA Yujie WU Jianghua WAN Yuping YAN Fang ZHOU | 2017 | Journal of Meteorological Research2017，31，1： | 13 |

| 3 | The Sources and Transport Patterns of Modern Sediments in Hangzhou Bay: Evidence from Clay Minerals显示文摘Clay mineral compositions of 199 offshore surface sediment samples collected from the Hangzhou Bay have been analyzed. The clay minerals in the sediments from the Hangzhou Bay are dominated by illite(58.7%, on average), followed by chlorite(20.3%), kaolinite(16.9%) and smectite(4.1%). Two provinces were classified by Q-mode cluster analysis. Class Ⅰ with relatively low amounts of illite and smectite is widely distributed in the Hangzhou Bay, especially concentrated in the top and mouth of the bay, and the northern and southern nearshore areas. Class Ⅱ with comparatively high amounts of illite and smectite is mainly concentrated in the central part of the bay with the water depth of 8–10 m. By comparing clay mineral compositions with the neighbouring regions, we can find that the sediments in the Hangzhou Bay are mainly influenced by the resuspension and repeated deposition of particles from the Yangtze River due to the strong dynamic environment. In particular, the clay fraction of Class Ⅰ is mainly supplied by the Yangtze River, while the sediments of Class Ⅱ are mixture of the clay minerals carried by the Yangtze River and Qiantang River. In general, the distributions of clay minerals in the northern bay are affected by Yangtze River runoff, coastal current and flood tide together, and in the southern they are mainly affected by the Qiantang River runoff and ebb tide. | LIU Jinqing CAO Ke YIN Ping GAO Fei CHEN Xiaoying ZHANG Yong YU Yiyong | 2018 | Journal of Ocean University of China2018，17，6： | 4 |
| 4 | High-Order Interpolation Algorithms for Charge Conservation in Particle-in-Cell Simulations显示文摘High-order interpolation algorithms for charge conservation in Particle-inCell(PIC)simulations are presented.The methods are valid for the case that a particle trajectory is a zigzag line.The second-order and third-order algorithms which can be applied to any even-order and odd-order are discussed in this paper,respectively.Several test simulations are performed to demonstrate their validity in two-dimensional PIC code.Compared with the simulation results of one-order,high-order algorithms have advantages in computation precision and enlarging the grid scales which reduces the CPU time. | Jinqing Yu Xiaolin Jin Weimin Zhou Bin Li Yuqiu Gu | 2013 | Communications in Computational Physics2013，13，4： | 1 |

| 6 | Subseasonal Prediction of Early-summer Northeast Asian Cut-off Lows by BCC-CSM2-HR and GloSea5显示文摘Northeast Asian cut-off lows are crucial cyclonic systems that can bring temperature and precipitation extremes over large areas.Skillful subseasonal forecasting of Northeast Asian cut-off lows is of great importance.Using two dynamical forecasting systems,one from the Beijing Climate Center(BCC-CSM2-HR)and the other from the Met Office(GloSea5),this study assesses simulation ability and subseasonal prediction skill for early-summer Northeast Asian cut-off lows.Both models are shown to have good ability in representing the spatial structure of cut-off lows,but they underestimate the intensity.The skillful prediction time scales for cut-off low intensity are about 10.2 days for BCC-CSM2-HR and 11.4 days for GloSea5 in advance.Further examination shows that both models can essentially capture the initial Rossby wave train,rapid growth and decay processes responsible for the evolution of cut-off lows,but the models show weaker amplitudes for the three-stage processes.The underestimated simulated strength of both the Eurasian midlatitude and East Asian subtropical jets may lead to the weaker local eddy-mean flow interaction responsible for the cut-off low evolution. | Yu NIE Jie WU Jinqing ZUO Hong-Li REN Adam A.SCAIFE Nick DUNSTONE Steven C.HARDIMAN | 2023 | Advances in Atmospheric Sciences2023，40，11： | 1 |

| 8 | Effects of test levels on creep and relaxation characteristic parameters of stem for rice seedlings grown in plastic cell tray显示文摘Creep and relaxation characteristics of stem for rice seedlings grown in plastic cell tray were studied by static tensile testing,in order to determine the relationship between characteristic parameters(rheological model parameters,stress components and strain components)and test levels(stress levels and strain levels).Rice seedling stem specimen used in the test was 40 mm in length.And the applied test values for the creep and relaxation test ranged from 1.0-3.0 MPa and 1.5%-3.5%,respectively,each for 5 levels.The results indicated that elastic modulus in the creep and relaxation model was not affected by test levels.However,except that viscosity coefficientηkv was a constant andηm1 decreased with the increase of test levels,other viscosity coefficient and rheological time nonlinearly increased as the test levels increased.And strain components in the creep model and stress components in the relaxation model significantly increased as the test levels increased. | Jinqing Xiao Ruijun Ma Yu Chen | 2020 | International Journal of Agricultural and Biological Engineering2020，13，4： | 0 |
