A simple index explains land humidity trend differences
—
in ClimatologyNew index based on precipitation and evapotranspiration ratio reveals land relative humidity decreased substantially since 1973, reconciles climate model discrepancies, and improves hydroclimate.
CMIP6 models project stronger precipitation extremes in the Kosi Basin
—
in ClimatologyCMIP6 climate models project intensified precipitation extremes in the Kosi Basin, with 47-79% increases in rainfall by 2100, critical for flood risk management and water resource planning.
Africa shows rising droughts, heatwaves, and compound events
—
in ClimatologyStudy analyzes compound drought-heatwave events across Africa 1979-2024, revealing acceleration trends and spatiotemporal patterns with implications for climate vulnerability and adaptation.
Southern land evaporation linked to North China extreme rain
Study identifies atmospheric circulation patterns and cross-regional evaporation precursors driving extreme precipitation trends in North China using information flow analysis.
Global green wave shifts north and east
—
Study reveals accelerated north-east shift in global green wave trajectory, indicating restructured vegetation phenology and hemispheric productivity changes through 21st century.
Climate explains mean storm activity more than individual storm features
Machine learning reveals how seasonal climate and synoptic conditions differently control storm activity, with climate trends more strongly affecting storm heat anomalies than intensity.
Arctic extreme weather events have increased sharply
—
in ClimatologySeven-decade reanalysis reveals sharp increases and spatial shifts in Arctic bioclimatic extremes—droughts, winter warming and rain-on-snow—signaling novel stressors for cold ecosystems.
