variability in the tropical Indian Ocean. The content is organized as follows. A brief description of the CGCM along with its validity is given in the next section. In section 3 , two modes of decadal variability in the tropical Indian Ocean are presented. In particular, a detailed discussion on the real nature of the decadal IOD is given there. The final section summarizes the main results. 2. Model a. Model description The model data used in this study are obtained from an atmosphere–ocean–land CGCM

description The model used in this study is the GFDL CM2.1 ocean–atmosphere–land–ice global CGCM. Details of the model formulation are documented in Gnanadesikan et al. (2006 , ocean model), GFDL Global Atmospheric Model Development Team (2004 , atmosphere and land model), Delworth et al. (2006 , coupled model), Wittenberg et al. (2006 , ENSO), and Stouffer et al. (2006 , climate sensitivity). Here, only a brief description of the coupled model is provided. The ocean component of the coupled model is

, and water vapor are based on the Monin–Obukhov similarity theory; and the radiation scheme is derived from Morcrette et al. (1998) . Major changes in the model include implicit coupling of the atmosphere to the land surface ( Schulz et al. 2001 ), advective transport ( Lin and Rood 1996 ), a prognostic–statistical scheme for cloud cover ( Tompkins 2002 ), and a rapid radiative-transfer model for longwave radiation ( Mlawer et al. 1997 ). Model details may be found in Roeckner et al. (2003

1. Introduction The Indian summer monsoon (ISM) is one of the main components of the large-scale Asian summer monsoon. It is regulated by the thermal contrast between land and ocean, the large availability of moisture from the Indian Ocean, the earth’s rotation, and the radiation from the sun ( Webster 1987 ; Meehl 1997 ). It is characterized by large precipitation over India from June to September ( Parthasarathy et al. 1992 ). Additionally, the abundant rainfall in the Bay of Bengal is an

Characterizing and understanding interannual variability in the Indian Ocean, its relationship to global ocean–atmosphere variability, and its relationship to weather and climate variability over land is a topic of significant interest (e.g., Ju and Slingo 1995 ; Nicholls 1995 ; Harrison and Larkin 1998 ; Webster et al. 1998 ; Saji et al. 1999 ; Webster

1. Introduction The Indian Ocean is the only ocean that is bounded by land at the tropical latitudes around 26°N. On the climatological annual-mean basis, ship-based flux products indicate that there is net heat going into the ocean north of 15°S ( Hastenrath and Lamb 1979a , b ; Esbensen and Kushnir 1981 ; Hsiung 1985 ; Oberhuber 1988 ; da Silva et al. 1994 ; Josey et al. 1999 ). Of the heat stored by the ocean, part is released to the atmosphere, mostly by latent evaporation and

implies that the linearized ocean processes contribute to the formation of the IODM in early spring and late summer. From April to July, however, the forcing of the IODM cannot be explained in terms of oceanic processes. In those months, the nonlinear interaction in the coupled ocean–atmosphere dynamics may become important. Nevertheless, the role of the linearized oceanic processes during the formation of the IODM is discernible and can be explained by oceanic advection and entrainment in (2b
