Abstract Midlatitude baroclinic waves drive extratropical weather and climate variations. but their predictability beyond 2 weeks has been deemed low. Here we analyze a large ensemble of climate simulations forced by observed sea surface temperatures (SSTs) and demonstrate that seasonal variations of baroclinic wave activity (BWA) are potentially predictable. This potential seasonal p... https://goodvibesbadhabiters.shop/product-category/cbt/
