Deep-learning climate emulator ACE2 reveals a global decrease in tropical cyclone frequency in the 15th Century under an El Niño-like sea surface temperature pattern

The relatively short modern observational record limits our understanding of the relationship between global tropical cyclone (TC) frequency and sea surface temperature (SST), resulting in uncertain future TC projections. Using novel deep-learning-based past-millennium simulations with the Ai2 Clima... View More
