Interdecadal Pacific oscillation phase dominants near-term global monsoon precipitation changes
Precipitation is projected to increase in response to human-induced global warming over global monsoon region, with significant implications for water resources in these densely populated areas. While most climate models agree on the externally forced wetting signal in global monsoon precipitation (GMP), the chaotic nature of internal variability introduces substantial uncertainty in future projections, particularly in the near term. In this stud…
Increasing exposure of global croplands productivity to growing season heatwaves under climate warming
Growing season heatwaves that occur simultaneously over global croplands can negatively impact global food baskets. The long-term changes of growing season heatwaves, as well as their impacts on croplands productivity, are crucial to food security, but remain unclear. Here, we investigated changes in the frequency, intensity and magnitude of growing season heatwaves from the past to the future over the global croplands, based on observations and …
Contrasting East Asian climate extremes in 2020 and 2022 tied to zonal flow
Subtropical East Asia (STEA) experienced a historic flood in the summer of 2020, and historic drought and heatwaves in the summer of 2022. Previous studies emphasized the role of western Pacific subtropical high (WPSH), but there is a paradox that the contrasting climate extremes over STEA in 2020 and 2022 are both associated with anomalously strong WPSH. Given that local vertical motion has a dominant control on precipitation variability, here w…
Quantifying the extremity of 2022 Chinese Yangtze River Valley daily hot extreme
In 2022, an extreme heatwave struck the Yangtze River Valley (YRV) of China. Existing studies have highlighted its record-breaking magnitude by comparison with historical records using a fixed baseline. However, the quantification of extremity relies on the choice of baseline. While using fixed baseline allows us to understand the changes in extremes with the background warming, the use of moving baseline quantifies the extremity relative to rece…
Understanding uncertainties in projections of western North Pacific tropical cyclogenesis
Reliable projections of tropical cyclone (TC) activities in the western North Pacific (WNP) are crucial for climate policy-making in densely-populated coastal Asia. Existing projections, however, exhibit considerable uncertainties with unclear sources. Here, based on future projections by the latest Coupled Model Intercomparison Project Phase 6 climate models, we identify a new and prevailing source of uncertainty arising from different TC identi…
Anthropogenic warming of Tibetan Plateau and constrained future projection
Serving as ‘the water tower of Asia’, the Tibetan Plateau (TP) supplies water resources to more than 1.4 billion people. It is warming more rapidly than the global average over the past decades, affecting regional hydrological cycle and ecosystem services. However, the anthropogenic (ANT) influence remains unknown. Here we assessed the human contribution to the observed TP warming based on coupled climate simulations and an optimal fingerprinting…
Attribution of the record-breaking heat event over Northeast Asia in summer 2018
In summer 2018, an extraordinary heat wave with record-breaking high temperatures hit Northeast Asia. However, the contribution of atmospheric circulation to this heat wave remains unknown. In this study, we quantify the contribution of circulation by using the flow analogue method. It is found that Northeast China, Korea and Japan were the most affected areas by the heat event, from daily to monthly timescales. The persistent high temperature wa…
Future changes in precipitation over Central Asia based on CMIP6 projections
A stronger than global mean warming trend is projected over Central Asia in the coming century. Based on the historical simulations and projections under four combined scenarios of the Shared Socioeconomic Pathways and the Representative Concentration Pathways (SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5) provided by 15 models from the Sixth Phase of Coupled Model Intercomparison Project (CMIP6), we show a comprehensive picture of the future change…
Aerosol forcing of extreme summer drought over North China
The frequency of extreme summer drought has been increasing in North China during the past sixty years, which has caused serious water shortages. It remains unclear whether anthropogenic forcing has contributed to the increasing extreme droughts. Using the National Centers for Environmental Prediction and the National Center for Atmospheric Research (NCEP/NCAR) re-analysis data and Coupled Model Intercomparison Project Phase 5 (CMIP5) model simul…
Attribution of the July–August 2013 heat event in Central and Eastern China to anthropogenic greenhouse gas emissions
In the midsummer of 2013, Central and Eastern China (CEC) was hit by an extraordinary heat event, with the region experiencing the warmest July-August on record. To explore how human-induced greenhouse gas emissions and natural internal variability contributed to this heat event, we compare observed July-August mean surface air temperature with that simulated by climate models. We find that both atmospheric natural variability and anthropogenic f…
Impact of cloud radiative heating on East Asian summer monsoon circulation
The impacts of cloud radiative heating on the East Asian Summer Monsoon (EASM) over southeastern China (105°–125°E, 20°–35°N) are addressed by using the Community Atmosphere Model version 5 (CAM5). Sensitivity experiments demonstrate that the radiative heating of clouds leads to a positive effect on the local EASM circulation over southeastern China. Without the radiative heating of clouds, the EASM circulation and precipitation would be much wea…
