Unveiling the dynamics of sequential extreme precipitation-heatwave compounds in China

Abstract

Amidst the escalating impacts of global warming, the occurrence and severity of compound extreme weather events have risen significantly, presenting substantial threats to both lives and property. Existing response strategies predominantly focus on individual events, often overlooking the cumulative effects rising from their inherent complexity. To address this critical gap, we conducted a thorough examination of sequential extreme precipitation–heatwave compound events (SEPHCE) in China from 1975 to 2020, utilizing data from 1929 meteorological stations. Our investigation revealed a consistent rise in the frequency and duration of SEPHCE, with a particularly notable surge since 1993. Furthermore, shorter interval events disproportionately affected the regions of southwestern and southeast coastal China. Furthermore, SEPHCE onset times exhibited advancement, and the endings were delayed, thereby intensifying the overall trend. These findings underscore the pressing need to prioritize effective planning and adaptation strategies to mitigate the impact of these compound event, while also addressing the potential exacerbation of inequality resulting from climate change.

Understanding vegetation phenology responses to easily ignored climate factors in china's mid-high latitudes

“…China's vast expanse spans multiple climatic zones and hosts a diverse array of vegetation types 50 , positioning it as an unrivaled focal point for vegetation phenology research. This study concentrates on the region north of 30°N in China, recognized for its heightened sensitivity to global climate change and suitability for investigating climate impacts on vegetation phenology 51 .…”
