摘要
The East Asian Monsoon Marginal Zone(EAMMZ)lies in thetransition between two major climate zones:the East Asian monsoon zone and the arid region of Central Asia,resulting in complexclimate change patterns[1].Due to shifts in the northwestern Pacific subtropical high and variations in the westerly jet,the EAMMZexperiences significant precipitation fluctuations.These variationsin summer precipitation often trigger widespread droughts andfloods,leading to severe social and economic consequences[2].Understanding the key meteorological drivers behind dry/wetanomalies in the monsoon marginal zone is essential for informeddecision-making and the development of effective countermeasures.
