The El Niño/Southern Oscillation (ENSO) influences global climate as well as extreme weather events such as floods, droughts, and tropical cyclones, leading to large societal impacts globally have shown that El Niño—the warm phase of ENSO—effectively discharges oceanic heat into the central to eastern North Pacific basin through the subsurface ocean after its wintertime peak, resulting in high tropical cyclone activity during the following tropical cyclone peak season in the eastern North Pacific, which has significant implications for seasonal prediction of tropical cyclone activity in the
