“…This delay is likely associated with the wetting up of catchments over time (see Section 4.2). Therefore, while precipitation has been used as a proxy for flood damage in a number of previous short-term studies on compound wind-flood events (e.g., Martius et al, 2016;Owen et al, 2021b,a;Ridder et al, 2022;Li et al, 2022), these results highlight a potential to exaggerate the correlation between flooding and wind damage at lead times of less than ∼40 days.…”

“…For each compound extreme event, we calculate a series of metrics to quantify variations in its characteristics, such as the total days, duration, and intensity (Table 1). Specially, we use the definition of intensity for compound MHW-LChl extremes defined by Li D. et al (2022), which is expressed as the product of standardized SST anomalies and standardized Chl anomalies. The standardized anomalies are calculated by subtracting the climatological mean (i.e., 1993-2020) from each variable and dividing by the standard deviation.…”

The western Pacific Ocean is the global center for marine biodiversity, with high vulnerability to climate change. A better understanding of the spatiotemporal characteristics and potential drivers of compound marine heatwaves (MHWs) and low-chlorophyll (LChl) extreme events is essential for the conservation and management of local marine organisms and ecosystems. Here, using daily satellite sea surface temperature and model-based chlorophyll concentration, we find that the climatological spatial distribution of MHW-LChl events in total days, duration, and intensity exhibits heterogeneous distributions. The southwest sections of the South China Sea (WSCS) and Indonesian Seas are the hotspots for compound events, with total MHW-LChl days that are more than 2.5 times higher than in the other sub-regions. Notably, there is a trend toward more frequent (> 4.2 d/decade), stronger (> 0.5), and longer-lasting (> 1.4 d/decade) MHW-LChl occurrences in the WSCS. The occurrence of compound MHW-LChl extremes exhibits remarkable seasonal differences, with the majority of these events transpiring during winter. Moreover, there are generally statistically significant increasing trends in MHW-LChl events for all properties on both seasonal and inter-annual timescales. Furthermore, we reveal that the total days of compound MHW-LChl extremes are strongly modulated by large-scale climate modes such as the El Niño-Southern Oscillation and Dipole Mode Index. Overall, pinpointing MHW-LChl hotspots and understanding their changes and drivers help vulnerable communities in better preparing for heightened and compounded risks to marine organism and ecosystems under climate change.

“…In recent years, climate change has brought more frequent and intense extreme events to the world [1-3], posing a significant threat to human health [4][5][6], economic stability [7][8][9], and environmental safety on a regional and global scale [10][11][12]. Coastal areas are influenced by interactions between the ocean and the atmosphere, leading to the development of weather patterns, sea breezes, heatwaves, as well as coastal storms [13].…”

China’s coastal lands and seas are highly susceptible to the changing environment due to their dense population and frequent economic activities. These areas experience more significant impacts from climate change-induced extreme events than elsewhere. The most noticeable effects of climate change are extreme high temperatures and extreme precipitation. We employ an ensemble of multiple RCMs (Regional Climate Models) to investigate and project changes in temperature, precipitation, and Compound Heat-Precipitation Extreme events (CHPEs) over selected China’s coastal lands and seas for both historical (1985-2004) and future periods (2080-2099). The multi-model ensemble projects that daily temperature extremes will increase by 2.9°C to 5.4°C across China’s coastal lands and seas, with land areas showing a higher temperature increase than marine areas. Extreme precipitation shows a high geographical heterogeneity with a 2.8-3.9mm/d reduction over the 15-25°N marine areas while a 2.2-5.4mm/d increment over the 25°N-35°N land areas. We use the Clausius-Clapeyron relationship to reveal that the peak of daily extreme precipitation will increase by 2-7mm/d and the temperature at which extreme precipitation peaks will increase by 2°C to 6°C by warming. The land area of 25-30°N has the highest peak precipitation increase of 9.87mm/d and a peak temperature increase of 6°C. As precipitation extremes intensify with daily temperature extremes increase, CHPEs are projected to occur more frequently over both land and marine areas. Compared with the historical period, the frequency of CHPEs will increase by 40.9%-161.2% over marine areas, and by 36.2%-163.6% over land areas in the future. The 15-20°N area has the highest frequency increase of CHPE events, and the 25-30°N area has the largest difference in frequency increase under two different scenarios. It indicated that the 25-30°N area will be more easily affected by climate change.
