POGA and SPCZ experiments using CAM5

Two atmosphere-only experiments using CAM5, PAC-A and extended South Pacific Convergence Zone-A (each with 10 ensemble members), are conducted to compare with the fully coupled CESM1 tropical Pacific pacemaker (PAC-C) experiments. The uncoupled PAC-A experiment matches the coupled PAC-C in every way, apart from the inclusion of coupling outside of the tropical Pacific region. In this way, the PAC-A ensemble mean with external forcing removed (i.e., PAC-A minus LENS) isolates the direct atmospheric influence of tropical Pacific SST. In other words, the uncoupled PAC-A and coupled PAC-C simulations enable a similar comparison to identify the tropical Pacific SST influence on global SST and atmospheric teleconnections.
