Abstract This study aims to investigate the changing properties of drought events in Weihe River basin, China, by modeling multivariate joint distribution duration, severity and peak using trivariate Gaussian Student t copulas. Monthly precipitations Xi'an gauge are used illustrate meta‐elliptical copula‐based methodology for a single‐station application. copulas found produce better fit comparing with other six symmetrical asymmetrical Archimedean copulas, and, checked goodness‐of‐fit tests...
Abstract Compound dry and hot events (CDHEs) have increased significantly caused agricultural losses adverse impacts on human health. It is thus critical to investigate changes in CDHEs population exposure responding climate change. Based the simulations of Coupled Model Intercomparison Project Phase 6 (CMIP6), future are estimated under four Shared Socioeconomic Pathways scenarios (SSPs) at first. And then driving forces behind these analyzed discussed. The results show that occurrence...
Abstract Global warming has intensified the intensity of compound drought‐hot extremes (CDHEs), posing more severe impacts on human societies and ecosystems than individual extremes. The vulnerability global terrestrial under CDHEs, along with its key influencing factors, remains poorly understood. Based multiple remote sensing data, we construct a Vine Copula model to appraise vegetation attribute it climatic biotic factors for five different types. High is detected in central southern...
In drought frequency analysis, as the number of variables increases, joint behavior between these needs to be studied. Therefore, this study aims develop a flexible four-variate distribution function regional stochastic nature drought. Using run theory, duration, severity, peak, and inter-arrival time were abstracted from Standardized Precipitation Evapotranspiration Index (SPEI) aggregated at six months, observed in mainland China 1961 2013. As showed significant dependence properties...
Extreme precipitation events usually lead to economic, agricultural, and social losses globally. The bias of different global circulation models (GCMs) is a major challenge in the projection extreme climate regions. Revealing Coupled Model Intercomparison Project (CMIP) GCMs helpful for providing reference predicting understanding performance CMIP Phase 6 (CMIP6) GCMs. Eight indices were used describe based on daily data retrieved from Global Precipitation Climatology (GPCP) 19 CMIP6 Six...
Abstract Extreme precipitation events vary with different sub-regions, sites and years show complex characteristics. In this study, the temporal variations, trends significance change points in annual time series of 10 extreme indices (EPIs) at 552 seven sub-regions were analyzed using modified Mann–Kendall test sequential analysis. Three representative (extremely wet, normal extremely dry) from 1961 to 2017 selected by largest, 50%, smallest empirical frequency values China. The...
The precipitation in irrigation area and the runoff from upstream can reflect natural irrigated agriculture water supply situations. wetness–dryness encounter uncertainty of runoff, affected by different microclimate basin, lead to potential risk reservoir dispatching, which poses a threat food security. This study develops an innovative integrated modeling framework coupling Copula joint distribution multi–objective optimal operation model, multi–criteria decision–making CECG–VIKOR method...
Weihe River Basin of China In recent decades, changing environments destroyed the natural structure streamflow, making accurate streamflow prediction challenging. This study develops a multi-regime Markov-switching Generalized Autoregressive Conditional Heteroskedasticity (MS-GARCH) model to predict daily time series with structural breaks (SB), named ARIMA (Autoregressive Integrated Moving Average)-MS-GARCH model. Consequently, ARIMA-MS-GARCH is compared other classical single-regime...
