AI 中文摘要
气候服务对风险管理和经济规划至关重要。本文展示了使用ARP - GEM全球大气模型在2.6千米水平分辨率下进行的长达一个世纪的模拟。该模拟旨在补充和扩展法国最新气候服务中使用的模拟集。其关键特性是千米尺度分辨率的全球覆盖,能呈现依赖精细尺度的现象,对法国气候服务尤为重要,因诸多过程在全球模拟中被忽视。此外,法国海外领土分散,此方法可在单一框架内呈现。因缺乏海洋耦合,模拟使用规定海表面温度,这一局限将在未来解决。本研究证明了该方法的可行性,并突出了新一代气候建模对气候服务的益处。
英文摘要
Climate services are essential for risk management and economic planning. This paper presents a century-long simulation performed with the ARP-GEM global atmosphere model at 2.6 km horizontal resolution. This simulation was specifically designed to complement and extend the set of simulations used in the latest version of the French climate services. A key feature is its global coverage at kilometer-scale resolution, enabling the representation of phenomena that depend on such fine scales. This is especially relevant for French climate services, as many processes - particularly over islands and resolution-sensitive regions - are currently overlooked in global simulations. Additionally, France's overseas territories are globally dispersed, and this approach allows their representation within a single framework. A limitation of this simulation is the use of prescribed sea surface temperatures due to the lack of ocean coupling; this will be addressed in future work. The present study demonstrates the feasibility of this approach and highlights the benefits of this new generation of climate modeling for climate services.
