Ensemble variability in sea ice extent is greater in the mid-Pliocene summer, when half of the models simulate sea-ice-free conditions. This paper documents a tool that has been developed that can be used to accelerate the development and understanding of climate models. 8.6. Differences with resolution for the global model appear to come from downscaling effects rather than improved large-scale circulation. https://doi.org/10.5194/gmd-13-3465-2020. Spatial Inf.

Our coupling structure allows future versions of either parent model to be immediately integrated into WRF-GC. Analyses of the climate effects of 2050 aviation emissions have been conducted with two coupled Chemistry Climate Models (CCMs) including experiments with coupled ocean models. Query/Copy Unprocessed Noms. This work discusses the technical aspects of how a coupled model that simulates the ocean and the atmosphere can be augmented by data assimilation functionality provided in generic form by the open-source software PDAF (Parallel Data Assimilation Framework). https://doi.org/10.5194/acp-16-7317-2016. It will be shown that these two aerosols have a significant effect on the monsoon. Numerical climate models are used to make projections of future surface warming for different pathways of future greenhouse gas emissions, where future surface warming will vary from place to place. https://doi.org/10.5194/gmd-13-4663-2020.

Aerosol radiative forcing is a key uncertainty in our understanding of the human forcing of the climate, with much of this uncertainty coming from aerosol impacts on clouds. The CESM project is supported primarily by the National Science Foundation (NSF).Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR). Reducing this computational burden could potentially improve our ability to simulate the earth's climate at finer scales. vertical pressure velocity 12hr. Science advancement and societal needs require Earth system modelling with higher resolutions that demand tremendous computing power. https://doi.org/10.5194/gmd-13-3475-2020. We used earth observations to evaluate and improve the representation of land surface temperature (LST) and vegetation coverage over Iberia in CHTESSEL and SURFEX land surface models. https://doi.org/10.5194/acp-13-12525-2013. In this work, we propose an approach based on a probability density function that utilizes cloud condensates and saturation ratios to replace the assumption of critical relative humidity (RH). There are statistically significant positive and negative correlations, respectively, between winter haze days (WHDs) in China's Jing-Jin-Ji region and eastern Pacific and central Pacific El Niño events. SCAM has a long history of being used for parameterization development in CAM (e.g.,Bogenschutzetal.,2012;Gettelmanetal.,2008;Song&Zhang,2011),parametersensitivitytests(e.g., ...

Partridge, Philip Stier, Zak Kipling, and Congbin Fu. We show how the size distribution of dust is intrinsically related to the dust mass accumulation rates and that only considering a consistent size range allows for a consistent analysis of the global dust cycle. In the case of a coarser ocean grid, significantly stronger cyclone winds result, due to misaligned frictional vectors in the atmospheric dynamical core. vertical pressure velocity 12hr. Based on the selected configuration of surfaces, it can generate a maximum of four dewarped surfaces. In NorESM2, the atmospheric model CAM6-Nor replaces standard CAM.

This will pave the way for better inclusion of state-of-the-art results from existing intercomparison efforts carried out by the scientific community, such as GlacierMIP2 or ISMIP6, into sea-level projections. Zhanshan Ma, Chuanfeng Zhao, Jiandong Gong, Jin Zhang, Zhe Li, Jian Sun, Yongzhu Liu, Jiong Chen, and Qingu Jiang. It uses global, freely available data in a smart and state-of-the-art format. Abstract. Several works address the optimal placement of multiple cameras in various contexts. The collection and preparation of input data sets is tedious. Recent observational (Deser and Timlin 1997) and modeling (Saravanan et al. screen is the “Create Date” field. Seasonal bias induced by the global climate model is fully corrected. RegDB consists of images captured using RGB and thermal dual-camera system. First analyses reveal that increasing resolution does improve certain aspects of the simulated climate but that many other biases still continue, possibly related to phenomena that are still not yet resolved and need to be parameterized. Crop model emulators make agricultural simulations more accessible to policy or decision makers. By changing the droplet number concentration (, Huopo Chen, Huijun Wang, Jianqi Sun, Yangyang Xu, and Zhicong Yin. It has undergone rapid development since the first release in 2016 and is now a well-tested tool that provides end-to-end provenance tracking to ensure reproducibility. Average temperature and precipitation projections according to a wide range of forcings, spanning a wider range than the CMIP5 projections, are documented as global averages and geographic patterns. https://doi.org/10.5194/gmd-13-3507-2020. https://doi.org/10.5194/gmd-13-5175-2020.
