1 The global Alfven eigenmode (GAE) driven by nonlinear coupling between toroidal Alfven eigenmode (TAE) and tearing mode is found for the first time on HL-2A. TAE modes nonlinearly couple with low frequency tearing mode and lead to generation of Alfvenic sidebands with nAMs= 0, ±1, ±2… GAE driven by two AMs couple ： fAMa+ fAMb= fHFM ≈ 240kHz nAMa+ nAMb= nHFM= 0 Alfven mode code (AMC) calculation: The frequency is around 240kHz, which agree with experimental observation. The mode structures display global feature and cover fully normalized radius of ρ = 0−1.
