| 1 | An virtual numerical experiment to understand the impacts of recovering natural vegetation on the summer climate and environmental conditions in East Asia显示文摘By applying a regional integrated environmental model system (RIEMS), a virtual numerical experiment is implemented to study the impacts of recovering natural vegetation on the regional climate and environmental conditions. The results show that recovering the natural vegetation in large scale could have significant influence on summer climate in East Asia. Not only would it be able to change the surface climate, but also to modify to certain extent the intensity of monsoon circulation. Although this is a virtual experiment at an extremely ideal condition, the implication of the simulating results is that the on-going nation-wide activities to recover the crop land for forest and pasture must be managed according to the local natural climate, hydrological and soil conditions. Only under such a condition, would the recovering of natural vegetation bring about significant climate and environmental benefits at regional scale. | Congbin Fu Huiling Yuan | 2001 | Chinese Science Bulletin2001，46，14： | 30 |
| 2 | Global aridification in the second half of the 20th century and its relationship to large-scale climate background显示文摘The variation in surface wetness index (SWI), which was derived from global gridded monthly precipi- tation and monthly mean surface air temperature datasets of Climatic Research Unit (CRU), from 1951― 2002 over global land was analyzed in this paper. The characteristics of the SWI variation in global continents, such as North America, South America, Eurasia, Africa, and Australia, were compared. In addition, the correlation between the SWI variation of each continent (or across the globe) and the large-scale background closely related to SST variations, which affects climate change, was analyzed. The results indicate that the SWI variation shows distinct regional characteristics in the second half of the 20th century under global warming. A drying trend in the last 52 years occurred in Africa, Eurasia, Australia and South America, most obviously in Africa and Eurasia. North America shows a wetting trend after 1976. A 30-year period of dry-wet oscillation is found in South America and Australia; the latest is in a drying period in two regions. The results also revealed that global warming has changed the dry-wet pattern of the global land. South America and Australia have a drying trend despite in- creases in precipitation. This indicates that increases in surface air temperature cannot be ignored in aridification studies. Global dry-wet variation is closely related to large-scale SST variations: the drying trend in Africa and Eurasia and the wetting trend in North America are correlated with Pacific Decadal Oscillation (PDO); the interdecadal oscillation of SWI in South America and Australia is consistent with the interdecadal variation in Southern Oscillation Index (SOI). | MA ZhuGuo FU CongBin | 2007 | Science China Earth Sciences2007，50，5： | 17 |
| 3 | Advances in studying interactions between aerosols and monsoon in China显示文摘Scientific issues relevant to interactions between aerosols and the Asian monsoon climate were discussed and evaluated at the 33 rd 'Forum of Science and Technology Frontiers' sponsored by the Department of Earth Sciences at the Chinese Academy of Sciences. Major results are summarized in this paper. The East Asian monsoon directly affects aerosol transport and provides a favorable background circulation for the occurrence and development of persistent fog-haze weather. Spatial features of aerosol transport and distribution are also influenced by the East Asian monsoon on seasonal, inter-annual, and decadal scales. High moisture levels in monsoon regions also affect aerosol optical and radiative properties. Observation analyses indicate that cloud physical properties and precipitation are significantly affected by aerosols in China with aerosols likely suppressing local light and moderate rainfall, and intensifying heavy rainfall in southeast coastal regions. However, the detailed mechanisms behind this pattern still need further exploration. The decadal variation in the East Asian monsoon strongly affects aerosol concentrations and their spatial patterns. The weakening monsoon circulation in recent decades has likely helped to increase regional aerosol concentrations. The substantial increase in Chinese air pollutants has likely decreased the temperature difference between land and sea, which favors intensification of the weakening monsoon circulation. Constructive suggestions regarding future studies on aerosols and monsoons were proposed in this forum and key uncertain issues were also discussed. | WU GuoXiong LI ZhanQing FU CongBin ZHANG XiaoYe ZHANG RenYi ZHANG RenHe ZHOU TianJun LI JianPing LI JianDong ZHOU DeGang WU Liang ZHOU LianTong HE Bian HUANG RongHui | 2016 | Science China Earth Sciences2016，59，1： | 16 |
| 4 | Monsoon regions: the highest rate of precipitation changesobserved from global data显示文摘The global distributions of the rate of precipitation change at seasonal, interannual and interdecadal scales are computed from the observed global data sets. The analysis has revealed that the monsoon regions in Asia and West Africa, and to lesser extent Australia, have the highest rate of precipitation change at all time scales in the world. These changes are manifested as seasonal jump, high interannual and interdecadal variability and abrupt changes between climate regimes. | Congbin Fu Zhaomei Zheng | 1998 | Chinese Science Bulletin1998，43，8： | 12 |
| 5 | Change of precipitation intensity spectra at different spatial scales under warming conditions显示文摘The long-term change of the whole spectra of precipitation intensity in China is examined using observed daily data recorded at 477 surface stations for the period from 1961 to 2008. The results show a spatially coherent decrease of trace precipitation despite different reduction magnitudes among the regions. For measurable precipitation, significant regional and seasonal characteristics are observed. In autumn, the whole measurable precipitation decreased over Eastern China (east of 98°E). In summer and winter, a significant increase of heavy precipitation and decrease of light precipitation are detected south of Eastern China. In Western China, measurable precipitation is found to have increased in all four seasons. Composite analysis reveals a quasi-linear relationship between increasing surface temperature and precipitation on a global scale. The responses of precipitation at different intensities to the increased temperature are distinct, with a significant spectra-shifting from light to heavy precipitation. Compared with precipitation over the ocean, the amplification of heavy precipitation over land is relatively less, most likely constrained by the limited water supply. The response of regional precipitation to global warming shows greater uncertainties compared with those on the global scale, perhaps due to interference by more complex topography and land cover, as well as human activities, among other factors. | WU FuTing FU CongBin | 2013 | Chinese Science Bulletin2013，58，12： | 10 |
| 6 | Projection of global mean surface air temperature changes in next 40 years: Uncertainties of climate models and an alternative approach显示文摘The Fourth Assessment Report (AR4) of the Intergovernmental Panel of Climate Change (IPCC) concluded that the climate projection using climate models that took account of both human and natural factors provided credible quantitative estimates of future climate change; however, the mismatches between the IPCC AR4 model ensembles and the observations, especially the multi-decadal variability (MDV), have cast shadows on the confidence of the model-based decadal projections of future cli mate. This paper reports an evaluation of many individual runs of AR4 models in the simulation of past global mean tempera ture. We find that most of the individual model runs fail to reproduce the MDV of past climate, which may have led to the overestimation of the projection of global warming for the next 40 years or so. Based on such an evaluation, we propose an al ternative approach, in which the MDV signal is taken into account, to project the global mean temperature for the next 40 years and obtain that the global warming during 2011–2050 could be much smaller than the AR4 projection. | FU CongBin QIAN Cheng WU ZhaoHua | 2011 | Science China Earth Sciences2011，54，9： | 10 |
| 7 | Correlations between North Atlantic Oscillation Index in winter and eastern China Flood/Drought Index in summer in the last 530 years显示文摘The time series of winter North Atlantic Oscil-lation Index (NAOI) in the period of 1429-1983 developed by Glueck and summer Flood/Drought Index (FDI) of eastern China in the period of 1470-1999 from 100 stations are used in this paper to study the potential impact of North Atlantic Oscillation on the climate in China. The analysis has ex-plored some significant lag correlations between FDI and NAOI. The maximum positive correlation coefficients be-tween NAOI and area-mean FDI in eastern and northern China lagging 2-3 years reach at 0.001 significance level, and while there are also negative correlation between NAOI and FDI in central and southern China at significance level of 0.05-0.01. The correlation between FDI and NAOI is time-dependent, i.e. the correlation coefficients between two indices vary from period to period. The highest correlation appeared in the period of 1636-1742, around the Little Ice Age, with the significant level of far above 0.001. The second significant period was from 1951 to 1999, at the level of 0.005-0.002. Both the power spectrum analysis and Morlet wavelet transformation have presented an interesting phe-nomenon: the area-mean FDIs in eastern and northern China share almost the same oscillation periods with NAOI in the inter-annual, decadal and centurial scales’ oscillations, i.e. 4-5, about 10, 20-30, around 50 and 80-100 years, etc. The Mann-Kendall Rank Statistic test reveals the significant trend and decadal abrupt changes in the series of area-mean FDIs in eastern and northern China in the past 530 years, while the NAOI in the past 400 years, did not show such trend at the significance level, but presented more frequent changes than those of FDI in China. This difference is per-haps due to the fact that the amplitude of the extremes of reconstructed NAOI series is less than that from instrumen-tal records. | FU Congbin & ZENG Zhaomei Key Laboratory of Regional Climate-Environment for Temperate East Asia, Institute of Atmospheric Physics, Chinese Academy of Sciences START Regional Center for Temperate East Asia, Beijing 100029, China | 2005 | Chinese Science Bulletin2005，50，21： | 9 |
| 8 | Regional integrated environmental model system and its simulation of East Asia summer monsoon显示文摘A continuous 22-year simulation in Asia for the period of 1 January 1979 to 31 December 2000 was conducted using the Regional Integrated Environmental Model System (RIEMS 2.0) with NCEP Reanalysis Ⅱ data as the driving fields. The model processes include surface physics state package (BATS 1e), a Grell cumulus parameterization, and a modified radiation package (CCM3) with the focus on the ability of the model to simulate the summer monsoon over East Asia. The analysis results show that (1) RIEMS reproduces well the spatial pattern and the seasonal cycle of surface temperature. When regionally averaged, the summer mean temperature biases are within 1―2℃. (2) For precipitation, the model reproduces well the spatial pattern, and temporal evolution of the East Asia summer monsoon rain belt, with steady phases separated by more rapid transitions, is reproduced. The rain belt simulated by RIEMS 2.0 is closer to observation than by RIEMS 1.0. (3) RIEMS 2.0 can reasonably reproduce the large-scale circulation. | XIONG Zhe FU CongBin YAN XiaoDong | 2009 | Chinese Science Bulletin2009，54，22： | 9 |
| 9 | Climatic changes in the Twenty-four Solar Terms during 1960-2008显示文摘The temperature thresholds and timings of the 24 climatic Solar Terms in China are determined from a homogenized dataset of the surface air temperature recorded at 549 meteorological stations for the period 1960-2008 employing the ensemble empirical mode decomposition method.Changes in the mean temperature and timing of the climatic solar terms are illustrated.The results show that in terms of the mean situation over China,the number of cold days such as those of Slight Cold and Great Cold has decreased,especially by 56.8% for Great Cold in the last 10 years(1998-2007) compared with in the 1960s.The number of hot days like those of Great Heat has increased by 81.4% in the last 10 years compared with in the 1960s.The timings of the climatic Solar Terms during the warming period(around spring) in the seasonal cycle have advanced significantly by more than 6 d,especially by 15 d for Rain Water,while those during the cooling period(around autumn) have delayed significantly by 5-6 d.These characteristics are mainly due to a warming shift of the whole seasonal cycle under global warming.However,the warming shift affects the different Solar Terms to various extents,more prominently in the spring than in the autumn.The warming tendencies for Rain Water,the Beginning of Spring,and the Waking of Insects are the largest,2.43?C,2.37?C,and 2.21?C,respectively,for the period 1961-2007 in China as a whole.Four particular phenology-related climatic Solar Terms,namely the Waking of Insects,Pure Brightness,Grain Full,and Grain in Ear,are found to have advanced almost everywhere.In semi-arid zones in northern China,advances of the timings of these four climatic Solar Terms are significant,12-16,4-8,4-8,and 8-12 d,respectively,for the period 1961-2007.These quantitative results provide a scientific base for climate change adaptation,especially in terms of agricultural planning and energy-saving management throughout a year. | QIAN Cheng YAN ZhongWei FU CongBin | 2012 | Chinese Science Bulletin2012，57，2： | 8 |
| 10 | Observation-based Estimation of Aerosol-induced Reduction of Planetary Boundary Layer Height显示文摘Radiative aerosols are known to influence the surface energy budget and hence the evolution of the planetary boundary layer. In this study, we develop a method to estimate the aerosol-induced reduction in the planetary boundary layer height(PBLH) based on two years of ground-based measurements at a site, the Station for Observing Regional Processes of the Earth System(SORPES), at Nanjing University, China, and radiosonde data from the meteorological station of Nanjing. The observations show that increased aerosol loads lead to a mean decrease of 67.1 W m-2for downward shortwave radiation(DSR) and a mean increase of 19.2 W m-2for downward longwave radiation(DLR), as well as a mean decrease of 9.6W m-2for the surface sensible heat flux(SHF) in the daytime. The relative variations of DSR, DLR and SHF are shown as a function of the increment of column mass concentration of particulate matter(PM2.5). High aerosol loading can significantly increase the atmospheric stability in the planetary boundary layer during both daytime and nighttime. Based on the statistical relationship between SHF and PM2.5column mass concentrations, the SHF under clean atmospheric conditions(same as the background days) is derived. In this case, the derived SHF, together with observed SHF, are then used to estimate changes in the PBLH related to aerosols. Our results suggest that the PBLH decreases more rapidly with increasing aerosol loading at high aerosol loading. When the daytime mean column mass concentration of PM2.5reaches 200 mg m-2, the decrease in the PBLH at 1600 LST(local standard time) is about 450 m. | Jun ZOU Jianning SUN Aijun DING Minghuai WANG Weidong GUO Congbin FU | 2017 | Advances in Atmospheric Sciences2017，34，9： | 8 |
| 11 | Testing the ability of RIEMS2.0 to simulate multi-year precipitation and air temperature in China显示文摘RIEMS2.0 (Regional Integrated Environment Modeling System, Version 2.0) is now being developed starting from RIEMS1.0 by the Key Laboratory of Regional Climate Environment Research for Temperate East Asia, Institute of Atmospheric Physics, Chinese Academy of Sciences, China. In order to test RIEMS2.0’s ability to simulate long-term climate and its changes, as well as provide a basis for further development and applications, we compare simulated precipitation and air temperature from 1980 to 2007 (simulation duration from Jan. 1, 1979 to Dec. 31, 2007) under different cumulus parameterization schemes with the observed data. The results show that RIEMS2.0 can reproduce the spatial distribution of precipitation and air temperature, but that the model overestimates precipitation with the rainfall center moving northwestward and underestimates air temperature for annual simulations. Annual and interannual variations in precipitation and air temperature for different climate subregions are well captured by the model. Further analysis of summer and winter simulations shows that precipitation is overestimated, except for the Jianghuai-Jiangnan subregions in the winter, and the air temperature bias in the summer is weaker than in the winter. There are larger biases for precipitation and air temperature in semiarid subregions. Anomalies in precipitation and air temperature are also well captured by the model. Although a similar distribution can be found between observed data and simulated results under different cumulus parameterization schemes, these show differences in intensity and location. In sum, RIEMS2.0 shows good stability and does well in simulating the long-term climate and its changes in China. | ZHAO DeMing FU CongBin YAN XiaoDong | 2009 | Chinese Science Bulletin2009，54，17： | 4 |

| 15 | Performance of Convective Parameterization Schemes in Asia Using RegCM:Simulations in Three Typical Regions for the Period 1998–2002显示文摘This study discusses the sensitivity of convective parameterization schemes(CPSs) in the Regional Climate Model(version 4.3)(Reg CM4.3) over East/South Asia. The simulations using different CPSs in Reg CM are compared to discover a suitable scheme for this region, as the performance of different schemes is greatly influenced by region and seasonality. Over Southeast China and the Bay of Bengal, the Grell scheme exhibits the lowest RMSEs of summer precipitation compared to observed data. Moreover, the Emanuel over land and Grell over ocean(ELGO) scheme enhances the simulation, in comparison with any single CPS(Grell/Emanuel) over Western Ghats, Sri Lanka, and Southeast India. Over the Huang–Huai–Hai Plain(3H) and Tibetan Plateau(TP) regions of China, the Tiedtke scheme simulates the more reasonable summer precipitation with high correlation coefficient and comparable amplitude. Especially, it reproduces a minimum convective precipitation bias of 8 mm d-1and the lowest RMSEs throughout the year over East/South Asia. Furthermore, for seasonal variation of precipitation, the Tiedtke scheme results are closer to the observed data over the 3H and TP regions. However, none of the CPSs is able to simulate the seasonal variation over North Pakistan(NP). In comparison with previous research, the results of this study support the Grell scheme over South Asia. However, the Tiedtke scheme shows superiority for the 3H, TP and NP regions. The thicker PBL, less surface latent heat flux, the unique ability of deep convection and the entrainment process in the Tiedtke scheme are responsible for reducing the wet bias. | Shaukat ALI DAN Li FU Congbin YANG Yang | 2015 | Advances in Atmospheric Sciences2015，32，5： | 2 |

| 17 | COMPARISON OF SIMULATING MINERAL DUST AEROSOLS IN EAST ASIA BY TWO EMISSION SCHEMES显示文摘Two common surface-dust emission schemes using critical wind speed and friction velocity were com-pared with the regional climate model RegCM3 in East Asia. In the comparison, transport of mineral dust and its distri-bution were simulated from March to April, 2001. Simulation results were also compared with TOMS aerosol index, showing that obvious differences exist in dust emission quantity and its column burden simulated by the dust emission schemes of friction velocity and wind speed criteria. The results obtained by the wind speed criterion are higher than that by friction velocity, bringing forth the problem whether or not the dust emission scheme matches the model. The obvious difference in the two schemes also explains the uncertainty of simulating mineral dust aerosol by modeling. | Jian Wu Yanyan Xu Congbin FU Renjian Zhang Min Dai Yong Zhu | 2006 | China Particuology2006，4，6： | 2 |
| 18 | A new index to describe the tropical Asian summer monsoon显示文摘We define a new monsoon index (MV) as the product of relative vorticity and equivalent potential temperature using the long-term NCEP/NCAR reanalysis data. The MV index provides new insights into the intraseasonal and interannual variabilities of the broad-scale tropical Asian summer monsoon (TASM), including the South Asian summer monsoon (SASM) and the South China Sea summer monsoon (SCSSM). On the intraseasonal timescale, the pentad-to-pentad MV index bears a close relationship to the broad-scale rainfall in the TASM regions. Among 29 summers from 1979 to 2007, in 23/27 summers the correlation coefficients are higher than 0.7 in the SASM/SCSSM region. However, in fewer than 9 summers, the correlations between the broad-scale rainfall and the existing circulation indices are higher than 0.7. On the interannual timescale, various existing SASM circulation indices are moderately or well correlated with all-India summer monsoon rainfall, whereas their correlations with broad-scale SASM rainfall are weak. In contrast, the summer mean MV index correlates well with the broad-scale SASM rainfall and all-India summer monsoon rainfall (correlation of 0.73 and 0.65, respectively). In the SCSSM region, the summer mean MV index also bears a close relationship to the SCSSM rainfall, although some discrepancies exist during certain years. The composite strong TASM shows a stronger low-tropospheric low pressure in association with the enhanced westerly winds and moisture transfer, stronger convection, and upper-tropospheric easterly winds, which indicate that the MV index can well capture the features of TASM. | ZhongFeng Xu CongBin Fu YongFu Qian | 2009 | Science China Earth Sciences2009，52，6： | 2 |
