A solely radiance-based spectral angular distribution model and its application in deriving clear-sky spectral fluxes over tropical oceans
Advances in Atmospheric Sciences - Tập 33 - Trang 259-268 - 2015
Lei Song, Yinan Wang
The radiation budget at the top of the atmosphere plays a critical role in climate research. Compared to the broadband flux, the spectrally resolved outgoing longwave radiation or flux (OLR), with rich atmospheric information in different bands, has obvious advantages in the evaluation of GCMs. Unlike methods that need auxiliary measurements and information, here we take atmospheric infrared sound...... hiện toàn bộ
Validation of ECMWF and NCEP-NCAR reanalysis data in Antarctica
Advances in Atmospheric Sciences - Tập 27 - Trang 1151-1168 - 2010
Lejiang Yu, Zhanhai Zhang, Mingyu Zhou, Shiyuan Zhong, Donald Lenschow, Hsiaoming Hsu, Huiding Wu, Bo Sun
The European Center for Medium-Range Weather Forecast (ECMWF) Re-Analysis (ERA-40) and the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) ECMWF (ERA-40) and NCEP-NCAR reanalysis data were compared with Antarctic station observations, including surface-layer and upper-layer atmospheric observations, on intraseasonal and interannual timescales.

The numerical simulation of the three-dimensional teleconnections in the summer circulation over the Northern Hemisphere
Advances in Atmospheric Sciences - Tập 2 - Trang 81-92 - 1985
Huang Ronghui
In this paper, a quasi-geostrophic, 34-level spherical coordinate model with Rayleigh friction, Newtonian cooling and the horizontal eddy thermal diffusivity is used to simulate the three-dimensional teleconnection in the summer circulation over the Northern Hemisphere. The computed results show that the change of the heat source over the Tibetan Plateau may cause the change of the atmospheric cir...... hiện toàn bộ
Numerical study on the velocity structure around tidal fronts in the Yellow Sea
Advances in Atmospheric Sciences - Tập 20 - Trang 453-460 - 2003
Guimei Liu, Hui Wang, Song Sun, Boping Han
The velocity components across tidal fronts are examined using the Blumberg and Mellor 3-D nonlinear numerical coastal circulation model incorporated with the Mellor and Yamada level 2.5 turbulent closure model based on the reasonable model output of the M2 tide and density residual currents. In the numerical experiments, upwelling motion appears around all the fronts with different velocity struc...... hiện toàn bộ
Relationships between interannual and intraseasonal variations of the Asian-western Pacific summer monsoon hindcasted by BCC_CSM1.1(m)
Advances in Atmospheric Sciences - Tập 31 - Trang 1051-1064 - 2014
Xiangwen Liu, Tongwen Wu, Song Yang, Qiaoping Li, Yanjie Cheng, Xiaoyun Liang, Yongjie Fang, Weihua Jie, Suping Nie
Using hindcasts of the Beijing Climate Center Climate System Model, the relationships between interannual variability (IAV) and intraseasonal variability (ISV) of the Asian-western Pacific summer monsoon are diagnosed. Predictions show reasonable skill with respect to some basic characteristics of the ISV and IAV of the western North Pacific summer monsoon (WNPSM) and the Indian summer monsoon (IS...... hiện toàn bộ
Diurnal Variations of Precipitation over the Steep Slopes of the Himalayas Observed by TRMM PR and VIRS
Advances in Atmospheric Sciences - Tập 38 - Trang 641-660 - 2021
Xiao Pan, Yunfei Fu, Sen Yang, Ying Gong, Deqin Li
This study investigates diurnal variations of precipitation during May–August, 1998–2012, over the steep slopes of the Himalayas and adjacent regions (flat Gangetic Plains–FGP, foothills of the Himalayas–FHH, the steep slope of the southern Himalayas–SSSH, and the Himalayas-Tibetan Plateau tableland–HTPT). Diurnal variations are analyzed at the pixel level utilizing collocated TRMM precipitation r...... hiện toàn bộ
Total deformation and its role in heavy precipitation events associated with deformation-dominant flow patterns
Advances in Atmospheric Sciences - Tập 25 - Trang 11-23 - 2008
Shouting Gao, Shuai Yang, Ming Xue, Chunguang Cui
In this paper, it is elucidated that the total deformation (TD), defined as the square root of the sum of squared stretching deformation and squared shearing deformation, is an invariant independent of the coordinate system used. An idealized flow field is then constructed to demonstrate the confluence effect of a non-divergent and irrotational deformation field on moisture transport. To explore t...... hiện toàn bộ
Aircraft measurements of cloud–aerosol interaction over East Inner Mongolia
Advances in Atmospheric Sciences - Tập 34 - Trang 983-992 - 2017
Yuhuan Lü, Hengchi Lei, Jiefan Yang
To investigate the potential effects of aerosols on the microphysical properties of warm clouds, airborne observational data collected from 2009 to 2011 in Tongliao, Inner Mongolia, China, were statistically analyzed in this study. The results demonstrated that the vertical distribution of the aerosol number concentration (N a) was similar to that of the clean rural...... hiện toàn bộ
Mesoscale predictability of mei-yu heavy rainfall
Advances in Atmospheric Sciences - Tập 26 - Trang 438-450 - 2009
Jianyong Liu, Zhe-Min Tan
Recently reported results indicate that small amplitude and small scale initial errors grow rapidly and subsequently contaminate short-term deterministic mesoscale forecasts. This rapid error growth is dependent on not only moist convection but also the flow regime. In this study, the mesoscale predictability and error growth of mei-yu heavy rainfall is investigated by simulating a particular prec...... hiện toàn bộ
A hybrid coupled model for the pacific ocean-atmosphere system. Part I: Description and basic performance
Advances in Atmospheric Sciences - Tập 32 - Trang 301-318 - 2015
Rong-Hua Zhang
A hybrid coupled model (HCM) is constructed for El Niño-Southern Oscillation (ENSO)-related modeling studies over almost the entire Pacific basin. An ocean general circulation model is coupled to a statistical atmospheric model for interannual wind stress anomalies to represent their dominant coupling with sea surface temperatures. In addition, various relevant forcing and feedback processes exist...... hiện toàn bộ
