Climate predictions using recent and high-resolution climate models are becoming important for effective decision-making designing appropriate change adaptation mitigation strategies. Due to highly variable data scarcity of the upper Blue Nile Basin, previous studies did not detect specific unified trends. This study discusses, past future projections under CMIP6-SSPs scenarios basin. For model...

The annual precipitation over the Tianshan Mountains experienced an inter-decadal transition shift towards increasing trend in late 1980s. This study conducts attribution analysis from atmospheric circulation factors based on Global Precipitation Climatology Centre (GPCC) dataset and NCEP/NACR reanalysis data. results show that (a) Winter is affected by multi-decadal oscillations with periods o...

Precipitation gauges are critical for assessing precipitation measurements at regional and global scales often used to adjust estimates from other instruments such as satellites. However, gauge-measured is affected by gauge-undercatch that larger solid precipitation. In the present work, two popular correction factors (CFs) were compared: one utilizes a dynamic model in Global Climatology Centr...

The high-altitude Indus basin is one of the most complex and inadequately explored mountain terrains in World, where reliable observations precipitation are highly lacking. Therefore, spatially distributed products developed at global/regional scale often used several scientific disciplines. However, large uncertainties estimates such data sets lead to suboptimal outcomes. In this study, perfor...

This study projects water availability and sustainability in Nigeria due to climate change. used Gravity Recovery Climate Experiment (GRACE) terrestrial storage data (TWS), Global Precipitation Climatology Center (GPCC) precipitation Research Unit (CRU) temperature data. Four general circulation models (GCMs) of the Coupled Model Intercomparison Project 5 were downscaled using best four downsca...

Quantifying rates of climate change in mountain regions is considerable interest, not least because mountains are viewed as “hotspots” where can anticipate or amplify what occurring elsewhere. Accelerating has extensive environmental impacts, including depletion snow/ice reserves, critical for the world's water supply. Whilst concept elevation-dependent warming (EDW), whereby stratified by elev...

This study examines the seasonal forecast of North American Multi-Model Ensemble (NMME) over Central Africa (CA), which encompasses a region world where economies countries are highly dependent on agriculture and livestock breeding. Following many regional climate perspectives, we evaluated 4 seasons: December to February (DJF), March May (MAM), June August (JJA), September November (SON) betwe...

This study aims at predicting the Standard Precipitation Index (SPI) drought class transitions in Portugal, considering the influence of the North Atlantic Oscillation (NAO) as one of the main large-scale atmospheric drivers of precipitation and drought fields across the Western European and Mediterranean areas. Log-linear modeling of the drought class transition probabilities on three temporal...
