Western North Pacific Anticyclone (WNPAC) is an important low-level atmospheric circulation system that conveys the El Nino effect on East Asia summer climate. In this talk I will review various theories on the WNPAC formation mechanisms, including local air-sea interaction in the western North Pacific, remote impact of tropical Indian Ocean SST, a combination mode that emphasizes nonlinear interaction between ENSO and annual cycle, and recently proposed enthalpy advection/Rossby wave modulation processes.
