  journal={Journal of Hydrology},
Abstract Projected droughts for 21st century over India have been analysed using precipitation and temperature data obtained from Regional Climate Models (RCMs) under Representative Concentration Pathways (RCPs) 4.5 and 8.5. Standardized Precipitation Index (SPI), Standardized effective Precipitation Evapo-Transpiration Index (SP*ETI) and Standardized Precipitation-Evapotranspiration Index (SPEI) at the timescale of 12-months have been used for drought characterization. The K-means clustering… 
Study on the Spatial and Temporal Characteristics of Mesoscale Drought in China under Future Climate Change Scenarios
In this study, precipitation, and temperature data from HadGEM2-ES under Representative Concentration Pathways (RCPs) 4.5 and 8.5 were used to evaluate drought in China in the 21st century. The
Spatio-temporal variation and future risk assessment of projected drought events in the Godavari River basin using regional climate models
The study focused on the Godavari River basin to understand the alteration in the drought phenomenon for future scenarios. The Standardized Precipitation Evapotranspiration Index (SPEI)-3 is
Evaluation and projection of drought over India using high-resolution regional coupled model ROM
Drought is a recurring insidious hydro-climatic extreme that adversely affects agriculture growth and leading to long-lasting severe impacts on regional water resources and ecosystem. A comprehensive
Climatological Drought Forecasting Using Bias Corrected CMIP6 Climate Data: A Case Study for India
This study forecasts and assesses drought situations in various regions of India (the Araveli region, the Bundelkhand region, and the Kansabati river basin) based on seven simulated climates in the
Future drought characteristics through a multi-model ensemble from CMIP6 over South Asia
Abstract To characterize future drought events over a drought prone area like South Asia is paramount for drought risk mitigation. In this paper, a five-model ensemble mean from CMIP6 was chosen to
Doubling of the population exposed to drought over South Asia: CMIP6 multi-model-based analysis.
Future 'plausible world' regional rivalry pathways (SSP3) scenario-combinations are strongly recommended into consideration for policymaking in regard to water management as well as migration planning over South Asia.
Uncertainties in runoff projection and hydrological drought assessment over Gharesu basin under CMIP5 RCP scenarios
Hydrological drought plays an important role in planning and managing water resources systems to meet increasing water demands due to population growth. In this study, the effects of climate change
Spatiotemporal assessment of drought hazard, vulnerability and risk in the Krishna River basin, India
Spatial and temporal assessment of drought hazard over the Krishna River basin of India has been performed using long-term (January 1901–December 2002) precipitation and temperature data. Various

Projected drought conditions by CMIP6 multimodel ensemble over Southeast Asia
Southeast Asia (SEA) is vulnerable to climate extremes due to its large and growing population, long coastlines with low-lying areas, reliance on agricultural sector developments. Here, the latest


Spatio-temporal variation of drought in China during 1961–2012: A climatic perspective
Summary Understanding the spatial and temporal variation of drought is essentially important in drought assessment. In most previous studies, drought event is usually identified in space and time
Spatiotemporal analysis of meteorological drought variability in the Indian region using standardized precipitation index
Grid (1° latitude × 1° longitude) level daily rainfall data over India from June to September for the years 1951–2007, generated by the India Meteorological Department, were analysed to build monthly
