Short Summary

This study investigates the projected intensification of drought in the Nile River Basin under climate change, emphasizing the increasing influence of atmospheric evaporative demand. It utilizes daily ensemble-mean Standardized Precipitation Evapotranspiration Index (SPEI) derived from 12 NEX-GDDP-CMIP6 Global Climate Models (GCMs) to assess future drought conditions.

Objective

• To assess the intensification of drought in the Nile River Basin under climate change scenarios.
• To quantify the increasing influence of atmospheric evaporative demand on drought conditions in the Nile River Basin.

Study Configuration

• Spatial Scale: Nile River Basin (NRB)
• Temporal Scale: Daily (for SPEI derivation), under future climate change scenarios.

Methodology and Data

• Models used: 12 NEX-GDDP-CMIP6 Global Climate Models (GCMs)
• Data sources: Outputs from GCMs (precipitation, atmospheric evaporative demand) used to derive daily ensemble-mean Standardized Precipitation Evapotranspiration Index (SPEI).

Main Results

• Drought in the Nile River Basin is projected to intensify under climate change.
• Atmospheric evaporative demand is identified as an increasingly influential factor contributing to drought conditions in the region.

Contributions

• Provides a multi-model ensemble assessment of future drought intensification in the Nile River Basin.
• Highlights the critical and increasing role of atmospheric evaporative demand in driving future drought dynamics in the NRB.
• Utilizes daily ensemble-mean SPEI derived from NEX-GDDP-CMIP6 GCMs, offering detailed insights into drought projections.
