Abstract
- Tropical convection plays a key role in regional and global climate variability, and future changes in tropical precipitation under anthropogenic global warming are critical for projecting future changes in regional climate. In this study, by analyzing Coupled Model Intercomparison Project (CMIP) phase 6 models, we show that changes in projected tropical precipitation in CMIP6 models vary among models, but they are largely associated with the model’s warm pool intensity in the present-day (PD) climate. Models with stronger warm pools in the PD simulation tend to simulate an increase in precipitation in the central Pacific (CP) and a decrease in precipitation in the Maritime Continent (MC) under greenhouse warming. Significant differences in precipitation between the CP and MC regions induce low-level westerly anomalies over the west-central Pacific, favoring sea surface temperature warming in the CP region. This suggests that the associated air–sea interactions result in a particular tropical pattern in response to anthropogenic forcing.
