This study assesses the improvement of latest Coupled Model Intercomparison Project Phase 6 (CMIP6) over 5 (CMIP5) for precipitation simulation. Precipitation simulations under different future climate scenarios are also compared in this work. The results show that: 1) CMIP6 has no overall advantage CMIP5 simulating total (PRCPTOT) and maximum consecutive dry days (CDD). performance increases or decreases regionally PRCPTOT days. But it is slightly worse than very wet (R95pTOT). 2) Comparing...
Abstract In this study, we aim to better understand the current and future projections of precipitation extremes in Europe context climatic variability over a long-term period from last millennium end twenty-first century. The daily gridded data five global climate models (GCMs) phase 5 Coupled Model Intercomparison Project (CMIP5) are chosen investigate natural during (850–1849), historical (1850–2005) period, two representative concentration pathway (RCP2.6 RCP8.5) scenarios (2006–99)....
(1) Background: China is beginning to see increasingly complex real estate development dynamics as urbanization, industrialization and globalization advance. As a key driver of economic social in China’s cities, has created prosperity while facing the risk capitalization “hard landing”, making it difficult bring under control. (2) Methods: new approach that integrates “evolution dynamics–driving mechanism–policy design” constructed based on Boston Consulting Group matrix, exploratory spatial...
Abstract The relationship between coupled atmosphere–ocean general circulation model simulations and uncoupled made with specified SST sea ice is investigated using the Community Climate System Model, version 3. Experiments are carried out in a perfect framework. Two closely related questions investigated: 1) whether statistics of atmospheric weather noise same as model, 2) reproduces SST-forced response model. both found by removing forced response, determined from ensemble, field....
The interdecadal change in the relationship between El Niño–Southern Oscillation (ENSO) and atmospheric circulation over North Pacific is investigated using both observational data an general model. There are two prominent modes of winter mid-latitude variability Pacific: West (WP) teleconnection Aleutian Low (AL). ENSO WP-AL patterns changed notably around late 1970s. From 1957 to 1975, during mature phase ENSO, significant sea surface temperature anomalies (SSTAs) occurred, mainly...

Based on the centennial-scale observations and CMIP6 historical simulations, this paper employs ensemble empirical mode decomposition to extract decadal-to-multidecadal variability of land precipitation (DMVLP) in northern hemisphere. The spatial distributions dominant from orthogonal function are different four seasons. Regions with same sign anomalies likely be teleconnected through oceanic forcing. temporal evolutions leading modes similar winter spring, an amplitude increasing after late...
Abstract. Land use and cover have been significantly changed all around the world during last decade. In particular, Grain for Green (GG) program has resulted in significant changes regional land cover, especially China. change (LULCC) may lead to climate. this study, we take Yangtze River basin as a case study analyze impacts of LULCC reforestation on summer rainfall amounts extremes based Weather Research Forecasting model. Firstly, two observed scenarios (1990 2010) were chosen...
Abstract A coupled (ocean‐atmosphere) general circulation model (CGCM) and an uncoupled atmospheric forced with the SST external forcing of simulate similar 2 m air temperature (TS) trends also sea level pressure (SLP) for latter half 20th century. This suggests that inability models by observed to reproduce SLP in Indian Ocean could be due bias rather than lack coupling. The internally generated TS trend CGCM is found small comparison externally component. Intrinsic noise explains most...
Abstract Water resources severely constrain high-quality development in the Yellow River basin (YRB). Predicting trend of precipitation on basis satisfying precision has important guiding significance for future regional development. Using projected 12 CMIP6 models, this study applied most appropriate correction method each model from four quantile-mapping methods and changes annual YRB three key regions. The projection uncertainty was quantitatively assessed by addressing spread (MS) range....
General circulation models could simulate precipitation under climate change and have been recognized as a major tool to project future water resources, but huge inherent uncertainties mean that their credibility is widely questioned. The current analysis mainly focuses on some aspects of uncertainty few the whole chain process yield more reliable projection. This study proposes framework identify GCMs, consisting downscaling, (model spread Taylor diagram), ensemble (grid-based weighted...
Based on the daily precipitation from China Meteorological Administration and atmospheric circulation data Japanese 55-year Reanalysis (JRA-55) 1979 to 2018, this paper analyzes evolution of 10-30-day intra-seasonal oscillation (ISO) in Yangtze-Huaihe River Basin (YHRB) modulation heat source over Tibetan Plateau (TP) with different intensity peak trough values YHRB. When heating is strong southern flank TP (STP), lower-level anomalous low strengthens STP, which leads convergence airflow...
Based on the centennial-scale observations and re-analyses, this paper employs ensemble empirical mode decomposition to separate internal multidecadal variability (IMV) from externally-forced of sea surface temperature (SST), then defines new indices that represent IMV SST in North Pacific (NPIMV) South (SPIMV), respectively. The spatial structure NPIMV/SPIMV shows remarkably positive anomaly only index-defined region; meanwhile, temporal evolutions NPIMV SPIMV are uncorrelated, indicating...
The sea surface temperature (SST) or level pressure (SLP) has usually been used to measure the strength of El Niño–Southern Oscillation (ENSO) events. In this study, two new indices, based on upper-ocean heat content (HC), are proposed quantify “flavours” Niño (i.e., Cold Tongue (CTE) and Warm Pool (WPE)). Compared with traditional SST SLP HC-based indices can distinguish CTE WPE events much better also represent leading modes interannual variability atmosphere–ocean coupled system in...
The meridional propagation of the 30- to 60-day intraseasonal variability (ISV) precipitation in East Asian subtropical summer monsoon (EASSM) region and its monitoring prediction are investigated current study. Based on a multivariate empirical orthogonal function (MV-EOF) analysis relative vorticity at 700 hPa Asia, bivariate index referred as EASSM-ISV is designed using two leading MV-EOF modes, with objective real-time EASSM region. It found that this index, eight phases, can explain ISV...
Abstract The wintertime multidecadal land precipitation (WMLP) variability is obtained using the ensemble empirical mode decomposition, and then leading spatial pattern temporal evolution of WMLP in northern hemisphere during period 1891–2014 are investigated. time series shows a pronounced enhancement since mid‐1970s, coincident with 1976/1977 climate transition, variance increasing from 0.33 former (P1) to 2.57 latter (P2). structure P2 resembles that entire period. anomaly positive North...
Abstract It remains a key challenge to obtain reliable future precipitation estimates and their reliability under different climate scenarios. In this study, the deterministic projection of in Yellow River Basin (YRB) was obtained within Bayesian model averaging (BMA) framework. A probability estimation method based on BMA weighting scheme proposed probabilistic precipitation. We also analyzed credibility these two projections. The results showed that four indexes projected by an increasing...
