Integrating ENSO dynamics into physics-informed Graph Neural Networks for extreme evapotranspiration prediction under climate change
ENSO-aware spatio-temporal GNN embeds teleconnections via attention-based graphs.
CMIP6 ensemble projections show sustained ET increases under SSP2-4.5 and SSP5-8.5.
ENSO modulation amplifies ET extremes and spatial coherence toward late century.
SSP5-8.5 exhibits stronger ET amplification and enhanced spatial heterogeneity.
Multi-modal dual-target spatio-temporal graph learning for regional evapotranspiration estimation
Multi-modal dual-target spatio-temporal graph learning for regional evapotranspiration estimation
Multi-modal ST-GNN fused climate and satellite data for regional ET estimation.•
Dual-target learning improved MODIS ET skill using PM ET0 supervision.Graph learning outperformed a graph-free CNN + LSTM baseline.
Learned gating revealed seasonal shifts in climate and satellite relevance.
Useful ET forecasting skill was retained up to 12-month lead times.
Use of Gaussian mixture model for standardized precipitation index in monsoon region
Use of Gaussian mixture model for standardized precipitation index in monsoon region
Monsoon variability yields multimodal precipitation at 52–76% of stations.•
Single distributions often fail SPI normality at 3, 6, 9, 12, and 24 months.GMM improves fit where complexity peaks (mean Delta AIC approx −8 to −9).
Normality peaks at SPI-15/18; GMM provides relative gains at other scales.
Weibull suits SPI-15–21; GMM is preferred when precipitation is multi-peaked.
Insights into uncertainties in future drought analysis using hydrological simulation model
Insights into uncertainties in future drought analysis using hydrological simulation model
Hydrological simulation requires parameter calibration. This study quantifies uncertainties in future runoff and drought using the Soil and Water Assessment Tool, twenty general circulation models, and shared socioeconomic pathway scenarios. Results show calibration conditions significantly impact low-flow projections. While climate models dominate uncertainty, calibration choices contribute notably, highlighting the need for robust strategies in water resource planning.

The historical precipitation of CMIP6 GCM was overestimated, while the average temperature closely matched the reference data
The N75–N90 would be most vulnerable to climate change in the future, and S30–S60 would be dry in the future
Variability in the Northern Hemisphere is expected to increase further under high emission scenarios, while seasonal trends are projected to become more chaotic compared to the past
General Circulation Models' performances are different by each latitude and their simulations were overestimated for rainfall and well-estimated for temperature
The region in N75-N90 would be most vulnerable to climate change in the future, and the area in S30-S60 would be drier in the future
Variability of the northern hemisphere would increase more for high emission scenarios but seasonal trends are more chaotic than in the past
