The Atlantic Meridional Overturning Circulation (AMOC) timeseries at 26.5N was just updated (rapid.ac.uk). It appears that the AMOC has slightly rebounded in 2023 (16.00 Sv) from its minimum in 2022 (15.22 Sv). It is the 7th lowest annual mean AMOC value since 2005. 🌊🧪

Atlantic Nina has almost completely dissipated. At the same time, the Atlantic and Eastern North Pacific Warm Pools are becoming stronger. These may provide favorable conditions for hurricane development and intensification. A cold wake from the hurricane Erin is also clearly visible. 🌊🧪
