Abstract The standardized precipitation evapotranspiration index (SPEI) is computed and compared in China using reference calculated the Thornthwaite (TH) approach Penman–Monteith (PM) equation. analysis reveals that SPEI_PM outperforms SPEI_TH with regard to drought monitoring during period 1961–2012 over China, especially arid regions of China. Furthermore, also performs better observed variations soil moisture streamflow Thus, changes characteristics are detected on basis SPEI_PM. results...
Abstract Haze is a severe hazard that greatly influences traffic and daily life with great economic losses threats to human health. To enhance understanding of the haze occurrences, this study examined variations over North China their associated atmospheric circulations for period 1960–2012 using visibility data. Results indicate events region primarily occur in boreal winter year mainly morning day. The results analysis long‐term annual days were relatively few 1960s but increased steeply...
Abstract. In this paper, the variation and trend of haze pollution in eastern China for winter 1960–2012 were analyzed. With overall increasing number days period, 5 decades divided into three sub-periods based on changes (WHD) central North (30–40° N) South (south 30° east 109° E mainland China. Results show that WHD kept gradually during 1960–1979, remained stable 1980–1999, increased fast 2000–2012. The author identified major climate forcing factors besides total energy consumption....
The statistical spatial‐temporal features of the intense snowfall event (ISE) in China are investigated over period 1962–2000. results indicate that eastern China, northern Xinjiang, Tibetan plateau, and northeastern four key regions for ISE, with more frequency strong variability. Annual cycle analysis shows ISE exhibits a unimodal distribution maximum at winter months bimodal early spring Xinjiang autumn plateau. Linear trend indicates last 39 years, decreasing an increasing linear is weak...
In July–August (JA) of 2016, northeastern China (NEC) suffered from the most severe hot drought event past 50 years, leading to profound impacts on agriculture, ecosystem, and society. Results indicate that loss sea ice over Barents Sea (SICBS) in March might have influenced events NEC JA for period 1997–2016. Further analyses reveal lower SICBS is closely related thinner snow depth western Eurasia (SDWEA) April. The decline SDWEA leads drier soil Yangtze River valley northern during...
In this study, the water vapor sources for precipitation processes in southeastern China (SECN) during 1981–2010 were investigated using atmospheric reanalysis data. We also studied factors influencing summer moisture over SECN. These two issues are all closely related to climate signals recorded stalagmites recovered from caves Result supports that SECN whole time is primarily transported Indian Ocean. However, vertically integrated content throughout year has main sources: Ocean and...
Abstract. Atmospheric pollution has become a serious environmental and social problem in China. Over the past 30 years, number of winter (December–February) haze days over North China Plain (WHDNCP) was greatest 2014. In addition to anthropogenic influence, climate anomalies also played role. Thus, it is necessary analyze anomalous atmosphere circulations associated with this year detail. Near surface, weaker East Asian monsoon pattern, causing southerly winds Plain, could aggravate...
Climate change is expected to influence the occurrence and magnitude of precipitation-related extremes increase drought flood risk. Thus, future changes in dryness wetness over global land areas are analysed using climate simulations from World Research Programme's (WCRP) Coupled Model Intercomparison Project Phase 5 (CMIP5) under RCP4.5 forcing scenario. reproducibility evaluated first, it shown that high performance can be achieved present-day by models, particularly multi-model ensemble...
Abstract Based on the long-term reanalysis datasets and multivariate copula method, this study reveals that frequency of summer hot drought events (SHDEs) over northeastern China (NEC) shows interdecadal variations during 1925–2010. It is revealed sea surface temperature (SST) North Atlantic has a significant positive correlation with SHDEs NEC decadal time scale, indicating potential influence multidecadal oscillation (AMO). Further analyses indicate phases AMO, warming SST can trigger...
Abstract A comparison assessment of model capabilities in simulating precipitation extremes across China was first implemented by using 30 models from the Coupled Model Intercomparison Project Phase 5 (CMIP5) and 36 CMIP6 models. The results indicate that multi‐model median ensembles (MME) both CMIP5 can reasonably reproduce climate means for period 1986 to 2005, biases are lower most compared models, especially over southern China. To provide further comparisons, 14 selected with their...
Abstract Precipitation extremes and associated hazards often cause agricultural losses infrastructure damage even exert negative impacts on human health. It is thus crucial to assess future changes in precipitation exposure under warming scenarios improve the mitigation of climate change. On basis Coupled Model Intercomparison Project phase 6 simulations, we find that occurring probabilities exceed 99th percentile threshold are projected increase over global lands coming century, especially...
China is now confronting the intertwined challenges of air pollution and climate change. Given high synergies between abatement change mitigation, Chinese government actively promoting synergetic control these two issues. The Synergetic Roadmap project was launched in 2021 to track analyze progress by developing monitoring key indicators. 2022 report first annual update, featuring 20 indicators across five aspects: governance system practices, structural transition, associated...
ABSTRACT More than 1000 years, the Meiyu–Baiu have shaped uniqueness of natural resources, civilization and culture in Yangtze River Basin China main islands Japan. In recent decades, frequent rainstorms droughts seemingly diminished misty features traditional rainfall. However, there is still no consensus on whether their nature suspended. this study, we quantitatively demonstrate that almost completely lost during 1961–2023, ∼80% which can be attributed to anthropogenic warming....
Abstract This paper discusses projections of heavy rainfall events in China during the 21st century based on daily precipitation data from Fourth Assessment Report's (AR4) Coupled General Circulation Models (CGCM). Results show that all three experimental scenarios (scenarios A2, A1B, and B1) project consistent changes frequency intensity at end century. In regions Northeast North China, there are no significant but remarkable increases rainfall, indicating enhanced is main contributor to...
ABSTRACT The science that humans are the cause of global warming, and associated climate change would lead to serious changes in extreme events, food production, freshwater resources, biodiversity, human mortality, etc. is unequivocal. After several political negotiations, a 2 °C warming has been considered be benchmark for such damaging changes. However, an increasing amount scientific research indicates higher levels increasingly likely. What world like if occurred? This study aims provide...
ABSTRACT This study documents recent changes in the characteristics of summer (July–August–September) precipitation Northeast China ( NEC ). A significant shift to less occurred 1999–2012 as compared with that 1984–1998. The reduced later period is closely associated large‐scale anomalous high pressure over East Asia and descending motion . Furthermore, reductions total cloud cover moisture content also contribute To investigate possible mechanism for decadal precipitation, a northeast Asian...
Abstract East Asian summer monsoon (EASM) prediction is difficult because of the monsoon’s weak and unstable linkage with El Niño–Southern Oscillation (ENSO) interdecadal variability its complicated association high-latitude processes. Two statistical schemes were developed to include interannual increment approach improve seasonal EASM’s strength. The applied three models [i.e., Centre National de Recherches Météorologiques (CNRM), Met Office (UKMO), European for Medium-Range Weather...
Abstract This study provides an estimate of the human influence on increases in daily precipitation extremes over China using data sets from multiple coupled climate models participating Coupled Model Intercomparison Project Phase 5. The effects forcings can be detected observed changes extremes, but external natural as well aerosols are not optimal fingerprint methods. Estimation showed that has increased by approximately 13% (1% to 25% for 90% confidence interval) average recent decades....
