在中国的神威超级计算机上建立一个具有在线综合气溶胶反馈的3公里水平分辨率非静力全球大气模拟系统(iAMAS)。
摘要:通过跨尺度大气模型的集成,以及多维并行结构、精细优化、手动向量化和并行化I/O分解等方法,建立了一个基于新一代Sunway超级计算机平台的集成大气模型(iAMAS),大大提高了计算效率并减少了I/O成本。使用iAMAS在全球范围内进行了包含粒子物理反馈的3千米水平分辨率的气象模拟,并将规模扩展至了3,900万个处理器核心,实现了每小时0.82天的模拟速度,在常规I/O情况下能够进行5天的全球天气预报。实验结果表明,增加空间分辨率到几千米,并引入在线集成粒子物理反馈,可以显著提高全球天气预报的准确性。
