The accuracy of monsoon seasonal predictions significantly impacts the lives of billions who depend on or are affected by monsoons, as it is essential for the water cycle, food security, ecology, disaster prevention, and the economy of monsoon regions. Given the extensive literature on Asian monsoon climate prediction, we limit our focus to reviewing the seasonal prediction and predictability of the Asian Summer Monsoon (ASM). However, much of this review is also relevant to monsoon predictions in other seasons and regions. Over the past two decades, considerable progress has been made in the seasonal forecasting of the ASM, driven by an enhanced understanding of the sources of predictability and the dynamics of seasonal variability, along with advanced development in sophisticated models and technologies. This review centers on advances in understanding the physical foundation for monsoon climate prediction (section 2), significant findings and insights into the primary and regional sources of predictability arising from feedback processes among various climate components (sections 3 and 4), the effects of global warming and external forcings on predictability (section 5), developments in seasonal prediction models and techniques (section 6), the challenges and limitations of monsoon climate prediction (section 7), and emerging research trends with suggestions for future directions (section 8). We hope this review will stimulate creative activities to enhance monsoon climate prediction.展开更多

文摘Migratory birds undertake regular seasonal movements between breeding and non-breeding grounds each year,often spanning intercontinental distances.Several migratory waterbirds are declining globally,owing to multiple threats from parts of annual migration.Therefore,understanding the spatial distribution and conservation challenges of migratory waterbirds is critical for effective flyway-scale conservation.In this study,we compiled a comprehensive dataset of 199 migratory waterbird species,mapped seasonal distribution,and identified population trends and threats along the East Asian-Australasian Flyway and Central Asian Flyway.Species richness exhibited latitudinal gradients along the two flyways,peaking at approximately 60°N in the breeding season and15°N in the non-breeding season.Migration distance and geographic spread significantly varied among orders.More than half of the waterbird species(50.75%)showed decreasing population trends;however,no significant difference in the proportion of population decline was noticed across flyways or orders.A total of 31 species(15.58%)were listed as threatened,most of which were concentrated in the East Asian-Australasian Flyway and primarily affected by the use of biological resources,pollution,and agricultural expansion.Overall,this study provides a comparative assessment of migratory waterbirds in Asian flyways.Our findings highlight the importance of multinational conservation efforts targeting key breeding and non-breeding regions,specifically for threatened species,and underscore the need for coordinated strategies to mitigate multiple,overlapping threats across flyways.These further emphasize that conservation actions should prioritize transboundary habitat networks and policy integration among flyway countries to enhance the long-term resilience of migratory waterbird populations.

文摘The commencement of the tropical Asian summer monsoon(TASM)in May is a crucial phase in its seasonal evolution,with critical implications for agriculture and water resources.Based on observational and reanalysis data,this study finds that the relationship between El Nino-Southern Oscillation(ENSO)and monsoon commencement experiences a notable interdecadal strengthening after 1976/77.While the response of tropical tropospheric temperature to ENSO remains largely unchanged,ENSO induces a stronger Walker circulation,a more pronounced equatorial Rossby wave,and an intensified extratropical Rossby wave train after 1976/77.These enhanced atmospheric processes,which directly reinforce the ENSO-TASM commencement relationship,are likely driven by interdecadal shifts in the structure and variance of ENSO.Post-1976/77,ENSO displays increased variance and a more coherent structure,with more pronounced sea surface temperature anomalies in the western North Pacific and subtropical North Pacific.Given the limitations of observational data,a 1000-year piControl experiment further confirms the role of ENSO variance changes in strengthening its influence on monsoon commencement.Our findings underscore the critical influence of evolving ENSO characteristics on climate anomalies such as monsoon commencement,offering potential insights for short-term climate prediction.

文摘0 INTRODUCTION.The Asian drylands,encompassing the northern East Asian monsoon region(NMA),the westerlies-dominated arid central Asia(ACA)and arid west Asia(AWA),are ecologically fragile areas and among the most sensitive regions to global change.These regions are significant dust sources of the Northern Hemisphere(e.g.,Uno et al.,2009),playing a vital role in global climate change and marine biogeochemical cycles.

文摘The Central Asian Orogenic Belt(CAOB)is one of the largest and best preserved accretionary type orogenic belts in the world.Due to its complex tectonic history,the timing and location of the final closure of the Paleo-Asian Ocean and its tectonic evolution have been hotly discussed.To determine the petrogenesis and tectonic characteristics of the poorly exposed Triassic volcanic-intrusive complex on the northern margin of the eastern North China Craton,the authors conducted a study of zircon Lu-Hf isotopes,integrated with zircon U-Pb dating and whole-rock geochemistry.Zircons from eight representative volcanic and intrusive samples yielded concordant U-Pb ages of 251-245 Ma.The volcanic and intrusive rocks are all characterized by enrichments in large ion lithophile elements and depletions in high field strength elements,and they have features similar to those of highly fractionated Ⅰ-type granites.TheεHf(t)values for the volcanic and intrusive rocks,respectively,range from-1.69 to+3.75(mean=+1.22)and-2.17 to+3.15(mean=+0.38),with two-stage model ages of 1035-1345 Ma(mean=1196 Ma)and 1073-1401 Ma(mean=1250 Ma).The Hf isotopic features indicate that these rocks were formed by partial melting of young crustal material that was newly accreted from the depleted mantle,together with a degree of contamination by other crustal material.The volcanic-intrusive complex was related to an active continental margin in a volcanic arc and syn-collisional setting,indicating that the Paleo-Asian Ocean was closed after the Middle Triassic(245 Ma)along the northern margin of the North China Craton.This provides a constraint on the timing of the change in tectonic setting in this area from compression to extension.The results enhance our understanding of the evolution of the Paleo-Asian Ocean.
