Researchers have developed a novel method combining Forward Flux Sampling (FFS) with a neural weather emulator called SDL-WXFormer to more accurately estimate tropical cyclogenesis rates. This technique allows for the calculation of how often a tropical disturbance intensifies into a hurricane-level storm, even in rare event scenarios that are difficult to capture with traditional ensemble sampling. The FFS method breaks down the intensification process into sequential steps, enabling the estimation of rates that vary by orders of magnitude and align with observed seasonal cycles. Case studies on specific Atlantic storms like Earl, Fiona, and Ian demonstrated the method's ability to diagnose the rate-limiting factors in storm development. AI
