ENSO and West Pacific Seasonality Driven by the South Asian Monsoon

ENSO and West Pacific Seasonality Driven by the South Asian Monsoon Tuckman, PJ; Smyth, Jane E; Li, Jingyuan; Lutsko, Nicholas J; Marshall, John The equatorial Pacific exhibits a clear seasonal cycle, with West Pacific SSTs being highest during boreal autumn and El Niño/Southern Oscillation (ENSO) events tending to peak during boreal winter. In this work, we use the concept of a monsoonal mode and idealized coupled simulations to show that the presence of a large land mass in the Northern Hemisp
