This survey paper is devoted to describe the generalized equilibrium feedback analysis (GEFA). In the framework of the equilibrium feedback analysis (EFA), Liu et al. (2008)［2］ developed a generalized EFA (GEFA) method to separate each ocean’s influence to the atmosphere. Furthermore, the GEFA also helps to understand different substrate’s influence to the atmosphere. In brief, the GEFA is a useful statistical method in the study of the oceanlandatmospheric interaction.
