Marine heatwaves (MHWs) can significantly impact marine ecosystems and socio-economic systems, their severity may increase with global warming. Nevertheless, research on the onset decline rates of MHWs remains limited, historical future variations are not yet fully understood. This study, therefore, analyzes spatiotemporal characteristics MHW by using sea surface temperature data from OISSTv2.1 CMIP6. The results indicate that during period 1982 to 2014, were higher in eddy-active mid-latitude current systems western tropical region but lower subtropical gyres. A remarkably high correlation (0.94) exists between rates; regions also tend have rates. Approximately 49.69% ocean exhibits an increasing trend rates, significant increases observed Eastern Equatorial Pacific. Meanwhile, 92.87% oceanic exhibit Looking ahead (2015~2100), both SSP245 SSP585 scenarios display consistent spatial patterns Kuroshio-Oyashio Extension, Gulf Stream, Antarctic Circumpolar Current, Brazil-Malvinas Confluence relatively Under scenario, than those under scenario. indicates as warming intensifies, more extreme likely occur. finding it is necessary pay attention rate when mitigating its potential impacts.
