[Recently published] The Indian Ocean Sea Surface Temperature Warming Simulated by CMIP5 Models during the Twentieth Century: Competing Forcing Roles of GHGs and Anthropogenic Aerosols

Date:2014-07-30    

Main conclusions 

  • The emission of anthropogenic aerosols has slowed down the warming trend induced by GHGs in the Indian Ocean by 0.34 K per century, mainly via its indirect aerosol effect.
  • Both the basin-wide warming effect of GHGs and cooling effect of AAs are established through atmospheric processes via radiative and turbulent fluxes.
  • The positive Indian Ocean dipole warming pattern is associated with the surface easterly wind anomaly along the equator, which is produced by GHGs increase but weakened by AAs via direct aerosol effects.

The anthropogenic aerosol has slowed down the warming rate induced by GHGs, especially through the indirect effect of aerosols.
