Climate response associated with the Southern Annular Mode in the surroundings of Antarctic Peninsula: A multimodel ensemble analysis
This paper is an attempt to extract an average picture of the response of the Southern Annular Mode (SAM) to increasing greenhouse gases (GHG) forcing from a multimodel ensemble of simulations conducted in the framework of the IPCC 4th assessment experiments. Our analysis confirms that the climate c...
