Overview

Global climate analysis reveals rising compound hot-dry and hot-wet extremes across 90% of global land, highlighting intensifying risks driven by ocean surface temperature variability.

Key Points

  • To assess the spatiotemporal trends, attribution, and large-scale oceanic drivers of compound meteorological and hydrological hot-dry and hot-wet extremes across global land from 1901 to 2019.
  • Analyzed warm-season historical records (1901–2019) to quantify compound meteorological (CMHDE, CMHWE) and hydrological (CHHDE, CHHWE) extremes globally.
  • Evaluated dependence structures, return periods, and runoff responses to temperature and precipitation extremes, linking patterns to ocean modes including ENSO, AMO, and DMI.
  • Compound meteorological and hydrological hot-dry and hot-wet extreme occurrences increased across more than 90% of global land from 1901 to 2019, with compound hot-wet extremes showing higher expansion rates.
  • High temperatures shortened compound event return periods in over 92% of land areas, while precipitation anomalies exerted a stronger influence on runoff variations than temperature.
  • Dominant sea surface temperature modes correlated positively with compound extreme occurrences, accounting for 75.9% to 84.0% of their total variability.
