Different interannual co-evolutionary models reveal how East Asia's jet stream and summer monsoon evolve together‎

The East Asian Subtropical Westerly Jet (EASWJ) and the East Asian Summer Monsoon (EASM) are two pivotal components of the East Asian monsoon system, shaping the precipitation distribution and climate over East Asia. Whether the co-evolutionary EASWJ–EASM relationship remains consistent under different climatic backgrounds has been a key question in both modern and paleoclimate research.
