The El Niño/Southern Oscillation (ENSO) drives substantial variability in tropical cyclone (TC) activity around the world1–3 . However, it remains uncertain how the projected future changes in ENSO under greenhouse warming4–8 will aect TC activity, apart from an expectation that the overall frequency of TCs is likely to decrease for most ocean basins9–11. Here we show robust changes in ENSO-driven variability in TC occurrence by the late twenty-first century.

The Project aims to enhance Early Warning Systems (EWSs) in the Pacific SIDS (Fiji, Papua New Guinea, Solomon Islands, Timor-Leste and Vanuatu) , thereby contributing to building greater resilience to hydrometeorological hazards in the region. The proposed scope of the hazards for which EWSs will be created or enhanced is severe weather – including tropical cyclones, floods, drought and sea predictions. The warnings will be issued and acted upon hours, days, weeks and - in the case of drought - months ahead of the hazard occurring.

The Secretariat of the Pacific Environment Programme (SPREP) is implementing the Climate Information Services for Resilient Development in Vanuatu (CISRD), or Vanuatu Klaemet Infomesen blong redy, adapt mo protekt (Van-KIRAP) Project.

The Ministry for Climate Change Adaptation, Meteorology, Geo-Hazards, Environment, Energy and Disaster Management, Government of Vanuatu, contracted NIWA (The National Institute of Water & Atmospheric Research Ltd.) for the ‘Supply, delivery and installation of Automatic Weather Stations (AWS) in six different locations in Vanuatu’ (SC G02).
