The GRIMs ensemble dataset for "A critical role of the North Pacific bomb cyclones in the onset of the 2021 sudden stratospheric warming"

The numerical model, the Global/Regional Integrated Model system (GRIMs) ensemble results which are initialized at 0000 UTC December 26, 2020, with JRA-55 reanalysis. CTL and PVinv_ANOM in the file name mean the control and sensitivity (North Pacific cyclone-removed initial condition) experiments, respectively.本数值模型即全球/区域一体化模式系统（Global/Regional Integrated Model system，GRIMs），其集合模拟结果以JRA-55再分析资料为初始场，于2020年12月26日世界协调时0000时完成初始化。文件名中的CTL与PVinv_ANOM分别对应控制试验与敏感性试验，其中敏感性试验采用了移除北太平洋气旋的初始条件。
