Abstract

A 20-member ensemble of CESM1 (1 degree spatial resolution) simulations in which time-evolving SST anomalies in the eastern tropical Pacific (10S-10N, 160-90W, with a linearly tapering buffer zone that extends to 20S and 20N, 180W to the American coast) are nudged to observations (NOAA Extended Reconstruction Sea Surface Temperature version 3: ERSSTv3b) during 1920-2013. In this way, the observed evolution of ENSO is maintained in each simulation (i.e., ENSO is the pacemaker), with the rest of the model's coupled climate system free to evolve. Note that only the SST anomalies, not the total SST, are nudged to observations, maintaining the model's mean state, including any model biases.
