Based on the positions of 1027 typhoons that passed through Western Pacific (WP), East China Sea (ECS), and South (SCS), results indicate category marine heatwaves (MHWs) significantly decreases or dissipates after a typhoon’s passage, with stronger causing more pronounced dissipation. The presence MHWs does not necessarily enhance typhoon intensity; in as many 151 cases, weakened despite MHWs. Furthermore, case studies were conducted using three traversed different regions—Hinnamnor (2022), Mawar (2023), Koinu (2023)—to investigate dual effects intensity their dissipation satellite observations ocean reanalysis datasets. Results show by increasing sea surface temperature (SST) heat content (OHC), while also strengthening stratification shallower mixed layer depth (MLD), creating favorable conditions for intensification. While may initially intensity, passage triggers intense vertical mixing upwelling, which disrupts MHW structures alters distribution, potentially leading to fluctuations. impact varies time space, can sustain strength loss induced typhoon. Additionally, variations OHC mean upper 100 m (T100¯) inner-core region (R50) than outer-core (R30), indicating energy exchange is concentrated inner core, broader air–sea interactions occur outer core. development SST but are highly susceptible rapid due typhoon-induced impacts, forming dynamic two-way interaction.

ABSTRACT Because of the rising global temperatures, Sargassum fusiforme (Harvey) Setchell, a commercially valuable seaweed, has experienced reduced yield and quality due to high temperatures from marine heatwave events. However, mechanisms underlying effects stress on S. remain unclear. In this study, carbon nitrogen assimilation processes in were analyzed. These results indicated that stress, especially at 30°C for 12 days, significantly increased levels hydrogen peroxide (83%), malondialdehyde (84.7%), relative conductivity (16.5%) algae, which suggested an increase algal damage. Morphologically, damaged thylakoid structure photosynthetic efficiency algae accumulated NADPH, ATP, α‐ketoglutarate significantly, resulting decreased content mannitol, product. Additionally, physiological transcriptomic revealed inhibited rate nitrate absorption activities most enzymes associated with accumulation, while upregulating glutamate dehydrogenase (GDH), suggesting crucial role GDH 's adaptation stress. terms amino acid composition, proline alanine sensitive treatment. Moreover, under natural environment simulation validation experiment, showed same performance as laboratory conditions. The events oxidative damage assimilation, ultimately leading negative growth algae. Thus, context rapid warming exacerbating events, our study provides insights high‐temperature‐resistant breeding ecological management coastal aquaculture.
