Multidecadal Changes in Atmospheric Dryness Over East Asia Dominated by Internal Climate Variability

Abstract Summer near‐surface vapor pressure deficit (VPD), a key measure of atmospheric dryness, has increased markedly across East Asia since 1980, yet the relative roles of external forcing and internal variability (IV) in its multidecadal changes remain unclear. Here we show t...

Changes in the tropical rainfall seasonal cycle dominated by mesoscale convective systems

Global warming is reorganizing atmospheric circulation and hydroclimate, and tropical rainfall is a key manifestation of this response. Yet how these large-scale changes are translated into the tropical rainfall seasonal cycle remains uncertain because organized convection, which...
