The Tibetan Plateau is regarded as the Earth's Third Pole, which is the source region of several major rivers that impact more 20% the world population. This high-altitude region is reported to have been undergoing much greater rate of weat...
Surface-Atmosphere Coupling Scale, the Fate of Water, and Ecophysiological Function in a Brazilian Forest [0.03%]
巴西的一片森林中的大气耦合尺度，水的命运及生态生理功能
Ian T Baker,A Scott Denning,Don A Dazlich et al.
Ian T Baker et al.
Tropical South America plays a central role in global climate. Bowen ratio teleconnects to circulation and precipitation processes far afield, and the global CO2 growth rate is strongly influenced by carbon cycle processes in South America....
Evaluation and Intercomparison of Five North American Dry Deposition Algorithms at a Mixed Forest Site [0.03%]
北美五种氮沉降模型在混合森林生态系统中的评价与比较研究

Zhiyong Wu et al.
To quantify differences between dry deposition algorithms commonly used in North America, five models were selected to calculate dry deposition velocity (V d) for O3 and SO2 over a temperate mixed forest in southern Ontario, Canada, where a...
VENM: An Algorithm to Accurately Calculate Neutral Slopes and Gradients [0.03%]
基于体积能量法的中性坡度和梯度计算算法-VENM
Sjoerd Groeskamp,Paul M Barker,Trevor J McDougall et al.
Sjoerd Groeskamp et al.
Mesoscale eddies stir along the neutral plane, and the resulting neutral diffusion is a fundamental aspect of subgrid-scale tracer transport in ocean models. Calculating neutral diffusion traditionally involves calculating neutral slopes an...
Strong Dependence of Atmospheric Feedbacks on Mixed-Phase Microphysics and Aerosol-Cloud Interactions in HadGEM3 [0.03%]
混合相微物理和气溶胶云相互作用对HadGEM3气候反馈的影响
A Bodas-Salcedo,J P Mulcahy,T Andrews et al.
A Bodas-Salcedo et al.
We analyze the atmospheric processes that explain the large changes in radiative feedbacks between the two latest climate configurations of the Hadley Centre Global Environmental model. We use a large set of atmosphere-only climate change s...
Greenhouse Gas Concentration and Volcanic Eruptions Controlled the Variability of Terrestrial Carbon Uptake Over the Last Millennium [0.03%]
过去一千年陆地碳吸收的变化受温室气体浓度和火山爆发的控制
Xuanze Zhang,Shushi Peng,Philippe Ciais et al.
Xuanze Zhang et al.
The terrestrial net biome production (NBP) is considered as one of the major drivers of interannual variation in atmospheric CO2 levels. However, the determinants of variability in NBP under the background climate (i.e., preindustrial condi...

Rimed hydrometeors (graupel or hail) are added to a stratiform cloud scheme for global models and tested in a variety of configurations. Off-line tests compare well to other cloud microphysics schemes with rimed ice used in mesoscale models...
Prescribing Zonally Asymmetric Ozone Climatologies in Climate Models: Performance Compared to a Chemistry-Climate Model [0.03%]
气候模型中环流不对称臭氧时空分布的设置及其与化学气候模式的比较研究
Cameron D Rae,James Keeble,Peter Hitchcock et al.
Cameron D Rae et al.
Three different methods of specifying ozone in an atmosphere-only version of the HadGEM3-A global circulation model are compared to the coupled chemistry configuration of this model. These methods include a specified zonal-mean ozone climat...
Applying Machine Learning to Improve Simulations of a Chaotic Dynamical System Using Empirical Error Correction [0.03%]
基于经验误差修正改善混沌动力系统模拟的机器学习方法
