Multiscale and seasonal meteorological drought variability in China’s Lancang River Basin: Relative roles of precipitation and potential evapotranspiration

Spatiotemporal variability and trends of precipitation, temperature, and evapotranspiration in the Muger sub-basin of the Abbay basin Ethiopia

This study used time series data from 1980 to 2022 to investigate spatiotemporal changes and trends of precipitation, temperature, and evapotranspiration in Muger sub-basin. The coefficient of variation (CV), precipitation concentration index (PCI), and seasonality index (SAI) were used to assess variability, while...

Shift in streamflow seasonality and regime due to precipitation variability in a snow-influenced mountainous watershed

In mountainous regions, water availability and flood hazards are tightly linked to the timing and seasonality of streamflow, making their analysis indispensable for sustainable resource planning. In this regard, this study examines changes in seasonality and precipitation in the Khiav Chai River watershed, a snow-i...

Characterization of meteorological drought variability over the Tigris–Euphrates Basin, Türkiye, using SPI and SPEI

Spatio-temporal assessment of hydro-climatic trends in the Upper Baro River Basin, Ethiopia

Understanding hydroclimatic variability is essential for sustainable water resource management. This study assesses hydro-climatic trends and spatio-temporal variability across the Upper Baro River Basin, Ethiopia (23,322 km 2 ). It uses historical records from 10 rainfall and 6 temperature stations from the Ethi...

Responses of stable vegetation to drought accumulation timescales and time lags in the Weihe River Basin

Introduction This study aimed to distinguish drought accumulation timescale from response timing in stable vegetation in the Weihe River Basin. Methods We analyzed MODIS enhanced vegetation index (EVI) and ERA5-Drought standardized precipitation evapotranspiration index (SPEI) data for 2003–2024 on the native 0.25° dro...

Spatial Coherence and Non-Stationary Drought Dynamics in Water Management Basins of Northern and Central Kazakhstan

This study investigates the spatiotemporal variability, spatial consistency, and non-stationarity of meteorological and hydrological droughts in three major water management basins (WMBs) of northern and central Kazakhstan: Nura–Sarysu, Esil, and Tobyl–Torgai. Long-term instrumental observations from meteorological sta...
