Abstract In this study, the variability of aridity over a semiarid zone in Northern China from 1961 to 2013 and its association with northernmost margin East Asian summer monsoon (EASM) intensity were investigated using composite analysis, correlative unrotated rotated empirical orthogonal function analyses. The results indicate that nonsignificant drying trend (0.03/10 years) occurs entire eastern zone, accompanied by southward retreat EASM (0.24°/10 years), (0.11/10 (0.28°/10 are most...
During winter, the December North Atlantic Oscillation (NAO) has an impact on following February East Asian trough (EAT), and a significant positive correlation exists between them. It is shown that circulation anomalies affected by NAO for January are primarily confined to Euro-Atlantic sector while they extend Asia during February, this related anomalous wave trains originating from southwestern spreading northeastern Atlantic, northern Europe, western Siberia, Asia. When phase in...
Abstract. Global surface temperature (ST) datasets are the foundation for global climate change research. Several ST have been developed by different groups in NOAA NCEI, NASA GISS, UK Met Office Hadley Centre & UEA CRU, and Berkeley Earth. In this study, a new dataset named China Merged Surface Temperature (CMST) was presented. CMST is created merging China-Land Air (C-LSAT1.3) with sea (SST) data from Extended Reconstructed Sea version 5 (ERSSTv5). The merge of C-LSAT ERSSTv5 shows...
ABSTRACT This article examines the ability of Beijing Climate Center System Model (BCC_CSM) in demonstrating prediction accuracy and leading modes summer precipitation over North Asia (NA). A dynamic‐statistic combined approach for improving NA is proposed. Our results show that BCC_CSM can capture part spatial anomaly features first two precipitation. Moreover, regains relationships such second mode empirical orthogonal function (EOF1 EOF2) precipitation, respectively, corresponds to...
Abstract Under global warming, cold winters over Northern Asia are highly correlated with the subsequent hot summers middle and lower reaches of Yangtze River valley ( MLYRV ). This high correlation may result from an oceanic bridge's effect in Western Pacific. The mechanism be described as follows: atmospheric circulation anomalies corresponds a simultaneous warmer Pacific warm pool WPWP ) by decreasing surface latent heat fluxes. sea temperature SST can persist move eastward gradually to...
During summer 2020, Southern China experienced an extremely dry and hot summer, which was identified as one of the top ten domestic weather climate extreme events in 2020 by Meteorological Administration. Summer mean precipitation, surface air temperature (TAS), number days (NHD) were about 25% dryer, 1.5℃ warmer, 11 larger than 1981–2010 normal. These are 4th largest precipitation deficit, highest TAS, 2nd NHD 1961–2020 record. The large-scale circulation anomalies over West Pacific...
Abstract This study investigates the prediction of southern China surface air temperature (SAT) in January and February using hindcast forecast dataset from second version National Centers for Environmental Prediction Climate Forecast System, 2 (NCEP CFSv2), period 1983–2017. The observed SAT is teleconnected with Euro-Atlantic dipole (EAD) North Atlantic Oscillation (NAO), respectively. also El Niño–Southern (ENSO) via bridge Philippine Sea anticyclone. CFSv2 better predicts than January,...
Abstract We investigate the uncertainty (i.e., inter-model spread) in future projections of boreal winter climate, based on forced response ten models from CMIP5 following RCP8.5 scenario. The sea level pressure (SLP) is large North Pacific, Atlantic, and Arctic. A major part these uncertainties (31%) marked by a pattern with center northeastern Pacific dipole over Atlantic that we label as Pacific–Atlantic SLP (PA ∆SLP ). PA associated distinct global surface temperature (SST) Arctic ice...
Using the monthly reanalysis data sets of National Center for Environmental Prediction (NCEP)/National Atmospheric Research (NCAR) 1961–2015, inter‐decadal change in inter‐annual water vapour transport over tropical Indian Ocean–western Pacific during summer and related mechanisms were analysed this article. The results show that two major modes anomalous (60°–140°E, 10°S–30°N) experienced a significant mid‐1980s. first mode (EOF1) shows anticyclonic northwestern moves significantly...
Abstract The Asian‐Australian monsoon (AAM) region is characterized as abundant summer rainfall, which provides fresh water resources for high‐density population there. research uses HadGEM3‐A‐N216 model simulations to compare the change of extreme rainfall intensity in AAM with and without anthropogenic influences. Although forcing exerts a weak impact on climatological mean distribution precipitation, it significantly increases precipitation at each degree most parts region, especially...
The occurrence of a Ural blocking (UB) event is an important precursor severe cold air outbreaks in Siberia and East Asia, thus significant to accurately predict UB events. Using subseasonal seasonal (S2S) models the European Centre for Medium-Range Weather Forecasts (ECMWF) Environment Climate Change Canada (ECCC), we evaluated predictability persistent on 18 26 January 2012. Results showed that ECCC model was superior ECMWF predicting development stage ten days advance, while had better...
During summer 2020, Southern China experienced an extremely dry and hot summer, which was identified as one of the top ten domestic weather climate extreme events in 2020 by Meteorological Administration. Summer mean precipitation, surface air temperature (TAS), number days (NHD) were about 25% dryer, 1.5 °C warmer, 11 larger than 1981–2010 climatologies. These are 4th largest precipitation deficit, highest TAS, 2nd NHD 1961–2020 record. The large-scale circulation anomalies over West...
The Yangtze River basin experienced record-breaking high temperatures in July–August 2022, leading the China Meteorological Administration to issue its first ever "red heat warning". We use simulations from Detection and Attribution Model Intercomparison Project (DAMIP) of Coupled 6 (CMIP6) investigate role anthropogenic drivers this extreme event. have demonstrated that strong Western Pacific Subtropical High (WPSH), attributed internal variability, serves as clear proximate driver for such...
The Yangtze River Basin (YRB) experienced record-breaking heatwaves (HWs) during the summers of 2013 and 2022. A comparative analysis their variations physical causes was undertaken using ERA5 reanalysis data to determine similarities differences between characteristics mechanisms. results show that duration 2022 HWs rank as second first longest, respectively, since 1950s. Both were associated with anomalous high pressure descending motions over middle lower reaches YRB in conjunction a...
Using the four-times daily and monthly-mean reanalysis datasets of NCEP/NCAR for 1958 to 2018 period, we investigate interannual variability June-July-August (JJA)–mean water vapor source sink over tropical eastern Indian Ocean-Western Pacific (TEIOWP) underlying mechanism. It is found that two major modes (EOF1 EOF2) anomalies TEIOWP present a southwest-northeast oriented dipole tripole. Specifically, when western maritime continent shows an anomalous source, northwestern characterized by...
