CESM1.1 LME offshoot: Sensitivity to season of volcanic eruption
The response of the El Niño/Southern Oscillation (ENSO) to tropical volcanic eruptions has important worldwide implications, but remains poorly constrained. Many eruption characteristics are poorly constrained, which may contribute to uncertainties in model solutions—for example, the season of eruption occurrence is often unknown and assigned arbitrarily. Here we isolate the effect of eruption season using experiments with the CESM1, varying the starting month of two large tropical eruptions, Tambora and Samalas. These sensitivity runs are branches from runs in the CESM1 Last Millennium Ensemble.
We kindly ask that you reference the following paper (and acknowledge the NCAR PaleoclimateWG and NSF/ NCAR CISL computing resources) when presenting results based on these simulations in either oral or written form.
