In addition to the CCMI and NCAR data we obtained MERRA U , V and T from the assimilated (ASM) (not analysis) collections, located on the NASA machines maintained by the NASA Center for Climate Simulation (NCCS). The ERA-I and JRA-55 U , V , T and ? fields were downloaded from the Research Data Archive at the National Center for Atmospheric Research, CCMI specified-dynamics simulations Data availability. The majority of the data of CCMI phase 1 used in this study can be obtained through the British Atmospheric Data Centre (BADC) archive, p.10, 2012. ,
CO performed the analysis of the CCMI simulations. CO, DP, DWW and HY conceived of the analysis and provided significant guidance on the paper and figures presented, SB performed the CCMI simulations in support of the CCMI phase 1 and provided constructive feedback on the paper.
