[MIS12-P10] Sea surface temperatures over the northwestern subtropical Pacific simulated by MIROC-ES2L: Past, Present and Future

Observation indicates an increasing trend of sea surface temperatures (SST) over the northwestern subtropical Pacific. While this increase in SSTs affect the local air temperature, typhoon intensity and coral reefs, climate models further predict a stronger warming in the future. To improve the confidence of future predictions of SSTs, it is crucial to verify whether climate models can reproduce current and past SST changes. Here we analyze numerical simulations conducted with a global climate model MIROC-ES2L targeting the past 120,000 years. Specifically focusing on summer SSTs, the model results are compared against observations and reconstructions. Through this, we verify the ability of the climate model to reproduce SST changes in response to radiative forcings (solar radiation, greenhouse gases, volcanic eruptions). This presentation introduces preliminary results, including the reproducibility of modern climate SSTs and comparisons of SST changes over the past 120,000 years.
