Short Summary

This study investigates the decadal variability of El Niño-Southern Oscillation's (ENSO) impact on North Tropical Atlantic (NTA) sea surface temperatures, revealing a modulation mechanism linked to tropical Pacific precipitation.

Objective

• Investigate the decadal stability of ENSO's impact on NTA SSTs and identify underlying modulation mechanisms.

Study Configuration

• Spatial Scale: Global climate models with a focus on the North Tropical Atlantic (NTA) region.
• Temporal Scale: Decadal variability over the 20th century, based on CMIP6 piControl runs.

Methodology and Data

• Models used: 40 Coupled Model Intercomparison Project Phase 6 (CMIP6) climate models.
• Data sources: PiControl runs from CMIP6 models.

Main Results

• ENSO's impact on NTA SSTs exhibits significant decadal variability, modulated by the background intensity of wintertime precipitation over the central-eastern tropical Pacific.
• Enhanced precipitation in key regions amplifies the NTA warming response through increased tropospheric heating and atmospheric stability.

Contributions

• This study identifies tropical Pacific precipitation as a contributing mechanism behind the decadal variability of ENSO's impact on NTA SSTs, offering new insights into remote climate impacts modulation.
