| Abstract | It remains an open question of whether the propagation from meteorological to ecological drought is accelerating under the intensifying hydrological cycle associated with global warming. Here, we investigate changes in drought propagation processes and the corresponding driving mechanisms during summer season for the Northern Hemisphere ecosystems (NHE) using multiple vegetation satellite remote sensing datasets from 1982 to 2015. The results reveal a distinct spatial pattern of decreasing drought propagation time (PT) from north to south, predominantly controlled by radiation, soil moisture, and vegetation types. Temporally, over the last three decades, the average PT in the NHE has significantly decreased by 2.64, 1.69, and 1.43 weeks under moderate, severe, and extreme drought scenarios, respectively. Approximately 60% of the NHE exhibit accelerating propagation, particularly in cropland and shrub located in the central-western United States, southwestern and eastern Europe, and the northeastern China, implying declining mean resistance of the ecosystems in these areas to drought. The accelerating drought propagation is mainly induced by warming, followed by an increase in radiation and a declining soil moisture. The observed accelerating drought propagation from the atmosphere to ecosystem highlights the necessity of effective actions to improve climate change resilience of the NHE. |
