“…However, unlike the significant response of HWT, the HWI exhibits little response to the strengthening or variability of the WPSH, in both the historical and future periods. In previous studies, the HWI in other tropical ocean regions also had little variation and typically did not exceed 2°C (Holbrook et al., 2019; Oliver et al., 2018; Qi et al., 2022; Yao et al., 2022). This is due to the SST‐clouds feedback in tropical regions.…”

A marine heatwave (MHW) event is a period of abnormally warm seawater that exceeds the climatological threshold during a distinct period (Hobday et al., 2016), and MHWs are directly affected by upper ocean warming and have substantial impacts on marine ecosystems (Holbrook et al., 2020;Oliver et al., 2021;Smale et al., 2019). Numerous studies have focused on the future changes in MHWs under different emission scenarios, including their frequency, duration, intensity, and spatial variations (Costa & Rodrigues, 2021;Oliver et al., 2019;S. Wang et al., 2023;. Previous studies have also revealed the mechanism of MHWs. A persistent high-pressure system over the ocean reduces cloud cover, increases insolation, and suppresses surface winds, leading to hot and dry weather which increases sea surface temperatures (SST) (

The satellite-based daily sea surface temperature was used to study the Marine Heat Wave (MHW) in the East China Sea. The seasonal variation of MHW is significant. In winter, the 200 m isobath on the shelf is identified as a section with high-frequency MHW. The duration of MHW is relatively long on the slope and deep basin, and mean intensity of MHW is obviously high in the central Taiwan Strait. In summer, the frequency of MHW is relatively high near the coast of the China Mainland. Meanwhile, the shelf section of the 200 m isobath is also high in frequency. Otherwise, the duration of MHW on the shelf is short. In the northern shelf, the mean intensity of MHW is obviously higher. The total days and maximum intensity of MHW are also discussed, aiming at giving near-fully description of MHW in the East China Sea.

“…As forementioned, many studies have been held on the role of changes in mean SST and SST variance in influencing MHW longterm trends (Oliver et al, 2018;Holbrook et al, 2019;Jacox, 2019;Oliver, 2019;Qi et al, 2022;Wang et al, 2022;Yao and Wang, 2022;Yao et al, 2022a;Cheng et al, 2023). However, studies concerning the ECMS remain limited, and no effective research to date has elucidated the spatio-temporal evolution of summer MHWs in response to the warming SST.…”

Marine heatwaves (MHWs) are a type of widespread, persistent, and extreme marine warming event that can cause serious harm to the global marine ecology and economy. This study provides a systematic analysis of the long-term trends of MHWs in the Eastern China Marginal Seas (ECMS) during summer spanning from 1982 to 2022, and occurrence mechanisms of extreme MHW events. The findings show that in the context of global warming, the frequency of summer MHWs in the ECMS has increased across most regions, with a higher rate along the coast of China. Areas exhibiting a rapid surge in duration predominantly reside in the southern Yellow Sea (SYS) and southern East China Sea (ECS, south of 28°N). In contrast, the long-term trends of mean and maximum intensities exhibit both increases and decreases: Rising trends primarily occur in the Bohai Sea (BS) and Yellow Sea (YS), whereas descending trends are detected in the northern ECS (north of 28°N). Influenced jointly by duration and mean intensity, cumulative intensity (CumInt) exhibits a notable positive growth off the Yangtze River Estuary, in the SYS and southern ECS. By employing the empirical orthogonal function, the spatio-temporal features of the first two modes of CumInt and their correlation with summer mean sea surface temperature (SST) and SST variance are further examined. The first mode of CumInt displays a positive anomalous pattern throughout the ECMS, with notable upward trend in the corresponding time series, and the rising trend is primarily influenced by summer mean SST warming. Moreover, both of the first two modes show notable interannual variability. Extreme MHW events in the SYS in 2016 and 2018 are examined using the mixed layer temperature equation. The results suggest that these extreme MHW events originate primarily from anomalous atmospheric forcing and oceanic vertical mixing. These processes involve an anomalous high-pressure system over the SYS splitting from the western Pacific subtropical high, augmented atmospheric stability, diminished wind speeds, intensified solar radiation, and reduced oceanic mixing, thereby leading to the accumulation of more heat near the sea surface and forming extreme MHW events.
