Global Increases in Compound Flood‐Hot Extreme Hazards Under Climate Warming

Geophysical Research Letters, Journal Year: 2022, Volume and Issue: 49(8)

Published: April 18, 2022

Under global warming, a novel category of extreme events has become increasingly apparent, where flood and hot extremes occur in rapid succession, causing significant damages to infrastructure ecosystems. However, these bivariate compound flood-hot (CFH) hazards have not been comprehensively examined at the scale, their evolution under climate warming remains unstudied. Here, we present first picture projected changes CFH by using cascade modeling chain CMIP6 models, satellite reanalysis data sets, bias correction, hydrological models. We find an increasing percentage floods will be accompanied change; joint return periods CFHs are decrease globally, particularly tropics. These decreasing largely driven indicate likely increase hazards, ultimately highlight urgent need conduct adaptation planning for future risks.

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

npj Climate and Atmospheric Science, Journal Year: 2024, Volume and Issue: 7(1)

Published: March 11, 2024

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

Rising risks of compound extreme heat‐precipitation events in China

International Journal of Climatology, Journal Year: 2022, Volume and Issue: 42(11), P. 5785 - 5795

Published: Feb. 12, 2022

Abstract While the changes of extreme weather and climate events have been well investigated, change compound (i.e., combinations multiple weather/climate extremes and/or hazards), which severely affect biophysical human systems, remains poorly understood. Here, we examine decadal trends subsequently (or “preconditioned”) heat‐precipitation precipitation preceded by an heat) across China during 1961–2016. We find that, on average, around one‐quarter summer over (especially western China) are heat event. In most areas China, fraction exhibits significant increases since 1960s, with a national mean increasing tendency 2.51%·decade −1 . Furthermore, rising in fractional contribution hot to parts accelerated more recent decades.

Published: June 30, 2022

Owing to amplified impacts on human society and ecosystems, compound events (or extremes) have attracted ample attention in recent decades. China is particularly vulnerable due the fast warming rate, dense populations, fragile ecological environment. Recent studies demonstrated tangible effects of climate change with mounting economy, agriculture, public health, infrastructure China, posing unprecedented threats that are increasingly difficult manage. Here, I synthesize progress associated China. Several lines evidence indicate an increase frequency intensity multiple types across Future directions studying suggested, including investigating extremes from a perspective, modeling Anthropocene, quantitative evaluations risks, holistic adaptation measures events.

Drought- and heatwave-associated compound extremes: A review of hotspots, variables, parameters, drivers, impacts, and analysis frameworks

Frontiers in Earth Science, Journal Year: 2023, Volume and Issue: 10

Droughts and heatwaves are rising concerns with regard to the frequent formation of compound or concurrent extremes (CEs), which can cause greater havoc than an individual event a higher magnitude. Recently, they have been frequently detected form CEs together other events (e.g., floods, aridity, humidity events) concurrently spatiotemporal lags. Therefore, this systematic review assesses these by reviewing following aspects: CE hotspots, events, variable combinations that CEs; analyzed parameters frequency severity); large-scale modes climate variability (CV) as drivers alongside approaches relate them impacts yield loss fire risk) impact integration from 166 screened publications. Additionally, three varied analysis frameworks summarized highlight different components drought- heatwave-associated CEs, is novelty study.
