North Atlantic tropical cyclones (TCs) have considerable interannual variability, with La Nina and the positive phase of the Atlantic Meridional Mode (AMM) tending to drive active hurricane seasons, and El Nino and the negative AMM often driving inactive seasons. Here, we analyze how active and inactive Atlantic hurricane seasons may change in the future using the high resolution Energy Exascale Earth System Model (E3SM). We performed atmosphere-only simulations forced by sea-surface temperature patterns characteristic of La Nina and the positive AMM jointly, and El Nino and the negative AMM jointly, in historical and future climates. Projected Atlantic TCs become more frequent in the future by approximately 34% during El Nino and negative AMM and by 66% during La Nina and positive AMM, with a significant increase in the portion of intense TCs. Warmer SSTs increase TC potential intensity, with reduced wind shear and increased mid-tropospheric humidity further supporting TC activity.
