Multidecadal Convection-permitting Simulations of Current and Future Climate over South America using WRF

A high-resolution convection-permitting climate change simulation was performed at 4 km grid spacing covering the entire continent of South America. The simulation was performed using Weather Research Forecasting (WRF) model. This dataset is from a 22-year simulation representing the current climate between January 2001 and January 2022. ERA5 data was used to initialize the model and force boundary every 3 hours. This high-resolution simulation allowed for much improved representation of topography, convection, and orographic precipitation and snowpack, resulting in a one-of-a-kind dataset tha...本数据集以4公里网格间距开展了覆盖南美洲全大陆的高分辨率对流容许气候变化模拟。本次模拟采用天气研究与预报（Weather Research Forecasting, WRF）模式完成。该数据集对应2001年1月至2022年1月共计22年的现代气候模拟时段。本模拟以ERA5数据作为模式初始场，并每3小时施加边界强迫。此次高分辨率模拟显著提升了地形、对流、地形降水及积雪的表征精度，从而形成了独树一帜的数据集……
