We investigate how ocean feedbacks and the diurnal cycle impact convective aggregation using a slab ocean coupled to a cloud resolving model. With a 20 m mixed layer ocean, aggregation occurs after 25 days. Thinner ocean layers slow the ons...
Evolving CO2 Rather Than SST Leads to a Factor of Ten Decrease in GCM Convergence Time [0.03%]
使GCM收敛时间减少一个数量级的是CO2的演变而非海表温度的演变

The high computational cost of Global Climate Models (GCMs) is a problem that limits their use in many areas. Recently an inverse climate modeling (InvCM) method, which fixes the global mean sea surface temperature (SST) and evolves the C ...
Extension of a gaseous dry deposition algorithm to oxidized volatile organic compounds and hydrogen cyanide for application in chemistry transport models [0.03%]
气态干沉积算法的扩展，应用于氧化挥发性有机化合物和氢氰酸的化学传输模型中的应用

The dry deposition process refers to flux loss of an atmospheric pollutant due to uptake of the pollutant by the Earth's surfaces, including vegetation, underlying soil, and any other surface types. In chemistry transport models (CTMs), the...

Tropical deep convection can aggregate into large clusters, which can have impacts on the local humidity and precipitation. Sea surface temperature (SST) gradients have been shown to organize convection, yet there has been little work done ...
Accurate Simulation of Both Sensitivity and Variability for Amazonian Photosynthesis: Is It Too Much to Ask? [0.03%]
准确模拟亚马逊地区光合作用的敏感性和可变性：要求过高了吗？

Estimates of Amazon rainforest gross primary productivity (GPP) differ by a factor of 2 across a suite of three statistical and 18 process models. This wide spread contributes uncertainty to predictions of future climate. We compare the mea...
A Generalized Interpolation Material Point Method for Shallow Ice Shelves. 2: Anisotropic Nonlocal Damage Mechanics and Rift Propagation [0.03%]
广义插值物质点法在浅冰架中的应用。2：各向异性非局部损伤力学和裂隙扩展

Ice shelf fracture is responsible for roughly half of Antarctic ice mass loss in the form of calving and can weaken buttressing of upstream ice flow. Large uncertainties associated with the ice sheet response to climate variations are due t...
A Generalized Interpolation Material Point Method for Shallow Ice Shelves. 1: Shallow Shelf Approximation and Ice Thickness Evolution [0.03%]
广义插值物质点法在浅冰架中的应用。1: 浅层近似和冰厚演变

We develop a generalized interpolation material point method (GIMPM) for the shallow shelf approximation (SSA) of ice flow. The GIMPM, which can be viewed as a particle version of the finite element method, is used here to solve the shallow...
Implementation and Impacts of Surface and Blowing Snow Sources of Arctic Bromine Activation Within WRF-Chem 4.1.1 [0.03%]
基于WRF-Chem 4.1.1的北极溴化物活化的地表和吹雪源的实现及影响研究

Louis Marelle et al.
Elevated concentrations of atmospheric bromine are known to cause ozone depletion in the Arctic, which is most frequently observed during springtime. We implement a detailed description of bromine and chlorine chemistry within the WRF-Chem ...
Machine Learning Emulation of Gravity Wave Drag in Numerical Weather Forecasting [0.03%]
机器学习在数值天气预报重力波阻力模拟中的应用

Matthew Chantry et al.
We assess the value of machine learning as an accelerator for the parameterization schemes of operational weather forecasting systems, specifically the parameterization of nonorographic gravity wave drag. Emulators of this scheme can be tra...
Improving CLM5.0 Biomass and Carbon Exchange Across the Western United States Using a Data Assimilation System [0.03%]
基于数据 assimination 系统改进 clm5.0 模式下美国西部的生物量及碳交换量

Brett Raczka et al.
The Western United States is dominated by natural lands that play a critical role for carbon balance, water quality, and timber reserves. This region is also particularly vulnerable to forest mortality from drought, insect attack, and wildf...
