Abstract

High-quality climate information tailored to cities' needs assists decision makers to prepare for and adapt to climate change impacts, as well as to support the targeted transition towards climate resilient cities. During the last decades, two main modelling approaches emerged to understand and analyse the urban climate and to generate information. Firstly, meso- and microscale urban climate models commonly resolve the street to city scale climate (1 m to 1 km) through simulating short “weather” type episodes, possibly under climate change conditions. Secondly, regional climate models (RCMs) are currently approaching the kilometer scale grid resolutions (1–4 km) and becoming increasingly relevant to understand the interactions of cities with the regional climate on timescales from decades up to a century. Therefore, the WCRP CORDEX Flagship Pilot Study “URBan environments and Regional Climate Change (FPS URB-RCC)” brings together the urban climate modelling community and the RCM community and focuses on understanding the interactions between urban areas and regional climate change, with the help of coordinated experiments with an RCM ensemble having refined urban representations. This paper presents the FPS URB-RCC, its main aims, as well as the initial steps taken. The FPS URB-RCC advances urban climate projections and information to support evidence-based climate action towards climate resilient cities.

更好地了解城市环境及其与区域气候变化的相互作用--世界气候研究方案 CORDEX 旗舰试点研究 URB-RCC

根据城市需求量身定制的高质量气候信息有助于决策者做好准备，适应气候变化的影响，并支持有针对性地向具有气候复原力的城市过渡。在过去几十年中，出现了两种主要的建模方法来了解和分析城市气候并生成信息。首先，中尺度和微尺度城市气候模型通常通过模拟短时 "天气 "类型事件（可能在气候变化条件下）来解决街道到城市尺度的气候问题（1 米到 1 公里）。其次，区域气候模式（RCMs）目前正在接近千米尺度的网格分辨率（1-4 千米），对于了解城市与区域气候在几十年到一个世纪的时间尺度上的相互作用变得越来越重要。因此，世界气候研究计划 CORDEX 旗舰试点研究 "城市环境与区域气候变化（FPS URB-RCC）"将城市气候模拟界和区域气候模拟界聚集在一起，借助具有精细城市表征的区域气候模拟集合进行协调试验，重点了解城市地区与区域气候变化之间的相互作用。本文介绍了 FPS URB-RCC、其主要目标以及已采取的初步措施。FPS URB-RCC 推进了城市气候预测和信息，以支持基于证据的气候行动，从而建设具有气候复原力的城市。
