Mechanical Forcing of Convection by Cold Pools: Collisions and Energy Scaling [0.03%]
冷池通过碰撞强迫对流:能量放大规律
Bettina Meyer,Jan O Haerter
Bettina Meyer
Forced mechanical lifting through cold pool gust fronts can trigger new convection and, as previous work highlights, is enhanced when cold pools collide. However, as shown by conceptual models, the organization of the convective cloud field...

K C Helfer et al.
Motivated by an observed relationship between marine low cloud cover and surface wind speed, this study investigates how vertical wind shear affects trade-wind cumulus convection, including shallow cumulus and congestus with tops below the ...
Simulating Erosion-Induced Soil and Carbon Delivery From Uplands to Rivers in a Global Land Surface Model [0.03%]
基于全球陆面模型的土壤和碳输移模拟及其关键过程评估
Haicheng Zhang,Ronny Lauerwald,Pierre Regnier et al.
Haicheng Zhang et al.
Global water erosion strongly affects the terrestrial carbon balance. However, this process is currently ignored by most global land surface models (LSMs) that are used to project the responses of terrestrial carbon storage to climate and l...
Self-Aggregation of Convective Clouds With Interactive Sea Surface Temperature [0.03%]
具有互动海面温度的对流云的自我聚合现象
S Shamekh,C Muller,J-P Duvel et al.
S Shamekh et al.
This study investigates the feedbacks between an interactive sea surface temperature (SST) and the self-aggregation of deep convective clouds, using a cloud-resolving model in nonrotating radiative-convective equilibrium. The ocean is model...
Number Formats, Error Mitigation, and Scope for 16-Bit Arithmetics in Weather and Climate Modeling Analyzed With a Shallow Water Model [0.03%]
数值格式、错误缓解和天气及气候模型中16位运算的运用范围分析——基于浅水模式研究
M Klöwer,P D Düben,T N Palmer
M Klöwer
The need for high-precision calculations with 64-bit or 32-bit floating-point arithmetic for weather and climate models is questioned. Lower-precision numbers can accelerate simulations and are increasingly supported by modern computing har...
The Global Sink of Available Potential Energy by Mesoscale Air-Sea Interaction [0.03%]
中尺度海气相互作用的全球位能通量sink分布
Stuart P Bishop,R Justin Small,Frank O Bryan
Stuart P Bishop
The thermal component of oceanic eddy available potential energy (EPE) generation due to air-sea interaction is proportional to the product of anomalous sea surface temperature (SST) and net air-sea heat flux (SHF). In this study we assess ...
Methane Emissions in a Chemistry-Climate Model: Feedbacks and Climate Response [0.03%]
含甲烷排放的化学气候模式中的反馈和气候响应
I Heimann,P T Griffiths,N J Warwick et al.
I Heimann et al.
Understanding the past, present, and future evolution of methane remains a grand challenge. Here we have used a hierarchy of models, ranging from simple box models to a chemistry-climate model (CCM), UM-UKCA, to assess the contemporary and ...

An important component of the carbon-cycle is subduction, for example of dissolved carbon, from the surface layers to depths of (102-103)m. Recently, attention has been focused on the contribution by small-scale, mesoscale M, and submesosca...
PEAT-CLSM: A Specific Treatment of Peatland Hydrology in the NASA Catchment Land Surface Model [0.03%]
PEAT-CLSM:NASA流域地表模型中对泥炭地水文学的特异性处理
M Bechtold,G J M De Lannoy,R D Koster et al.
M Bechtold et al.
Peatlands are poorly represented in global Earth system modeling frameworks. Here we add a peatland-specific land surface hydrology module (PEAT-CLSM) to the Catchment Land Surface Model (CLSM) of the NASA Goddard Earth Observing System (GE...
Unified Entrainment and Detrainment Closures for Extended Eddy-Diffusivity Mass-Flux Schemes [0.03%]
扩展涡扩散性质量流方案的统一卷入和脱离闭合形式
Yair Cohen,Ignacio Lopez-Gomez,Anna Jaruga et al.
Yair Cohen et al.
We demonstrate that an extended eddy-diffusivity mass-flux (EDMF) scheme can be used as a unified parameterization of subgrid-scale turbulence and convection across a range of dynamical regimes, from dry convective boundary layers, through ...
