Using hydrological simulation to evaluate the accuracy of satellite-based and reanalysis precipitation products always suffer from a large uncertainty. This study evaluates four widely used global with high spatial temporal resolutions [i.e., AgMERRA (AgMIP modern-Era Retrospective Analysis for Research Applications), MSWEP (Multi-Source Weighted-Ensemble Precipitation), PERSIANN-CDR (Precipitation Estimation Remotely Sensed Information using Artificial Neural Networks-Climate Data Record),...
The hydrological model is the primary tool for regional water resources management, allocation, and prediction. However, these models always suffer from large uncertainties multiple sources. Therefore, it necessary to conduct an uncertainty analysis before performing simulation. Sequential Uncertainty Fitting (SUFI-2), Parameter Solution (ParaSol), Generalized Likelihood Estimation (GLUE), Particle Swarm Optimization (PSO) integrated with SWAT-CUP software were used calibrate Soil Water...
In this study, 6 widely used precipitation products APHRODITE, CPC_UNI_PRCP, CN05.1, PERSIANN-CDR, Princeton Global Forcing (PGF), and TRMM 3B42 V7 (TMPA), were evaluated against gauge observations (CMA data) from 1998 to 2014, applied streamflow simulation over the Upper Yellow River basin (UYRB), using 4 hydrological models (DWBM, RCCC-WBM, GR4J, VIC). The relative membership degree (u), as comprehensive evaluation index in evaluation, was calculated by optimum fuzzy model. results showed...
Global reanalysis precipitation products could provide valuable meteorological information for flow forecasting in poorly gauged areas, helping to overcome a long-standing challenge the field. But not all data sources are suitable regions or perform same way hydrological modeling, so it is essential test suitability of before applying them. In this study, five widely used global high-resolution products—Asian Precipitation Highly Resolved Observational Data Integration Towards Evaluation...
Abstract Anthropogenic climate change (ACC) strengthens the global terrestrial water cycle (TWC) through increases in annual total precipitation (PRCPTOT) over land. While increase average PRCPTOT has been attributed to ACC, it is unclear whether this equally true dry and wet regions, given difference changes between two climatic regions. Here, we show regions twice as fast of globe during 1961–2018 both observations simulations. This faster projected grow with future warming, an intensified...
Abstract The spatial propagation patterns of meteorological drought events (MDEs) and underlying mechanisms contribute to elucidating forecasting evolution. In this study, gridded MDEs in the Yangtze River Basin (YRB) throughout entire year, wet season dry were extracted from 3-month Standardized Precipitation Evapotranspiration Index (SPEI-3) series. Event synchronization (ES) complex networks (CN) employed construct MDE for various periods. former utilized identify synchronized subregions...
The demand for accurate long-term precipitation data is increasing, especially in the Lancang-Mekong River Basin (LMRB), where ground-based are mostly unavailable and inaccessible a timely manner. Remote sensing reanalysis quantitative products provide unprecedented observations to support water-related research, but these inevitably subject errors. In this study, we propose novel error correction framework that combines from various institutions. NASA Modern-Era Retrospective Analysis...
Abstract High air temperatures and low atmospheric humidity can result in severe disasters such as flash droughts regions characterized by high (monsoon regions). However, it remains unclear whether responses of hot extremes to warming temperature are amplified on dry days well the response days. Here, taking eastern monsoon China (EMC) a typical region, we find faster increase drier summer days, decrease hotter indicating “hotter get drier” “drier hotter” (i.e., coupling extremes),...
Precipitation is a crucial element in the study of climate change and key component processes hydrological cycle. Changes precipitation therefore have wide ranging implications across various fields, including agriculture, ecology economic development. Known as ’Mother River China’, Yellow sixth longest river world second‐longest country, has unique political, cultural role China. Flowing through arid, semi‐arid semi‐humid regions, it well known for its high sand content limited water...
Abstract. Hydrological simulations are a main method of quantifying the contribution rate (CR) climate change (CC) and human activities (HAs) to watershed streamflow changes. However, uncertainty hydrological is rarely considered in current research. To fill this research gap, based on Soil Water Assessment Tool (SWAT) model, study, we propose new framework quantify CR CC HAs posterior histogram distribution simulations. In our quantitative framework, first impact “equifinality for different...
Investigating the synchronized structure and teleconnection patterns of meteorological drought events (MDEs) contributes to elucidating drought’s evolution. In this study, CN05.1 gridded dataset from 1961 2021 was utilized calculate 3-month standardized precipitation evapotranspiration index (SPEI-3) for each grid in Yangtze River Basin (YRB). Based on these SPEI-3 series, grid-based MDEs were then extracted. Subsequently, event synchronization complex networks employed construct MDE network...
