More frequent and intense heatwave events (HWEs) on the Tibetan Plateau (TP) present substantial threats to ecological hydrological systems. However, understanding changes in HWEs TP is limited, primarily from analyses at individual stations or single elements (glaciers, lakes). Here, using refined data, we quantify magnitude by aggregating multiple indicators into a comprehensive index explore influence of environmental factors over TP. Our findings indicate that has significantly increased since 21st century, especially autumn. From 1979–2000 2001–2022, hotspots migrated toward northwestern TP, whereas regions with most rapid increase shifted opposite direction. During inter-seasonal, spring winter, migration direction changed northwest first 22 years (1979–2000) southeast recent (2001–2022). We also find downward shortwave radiation plays significant role spatial stratified heterogeneity (SSH) magnitude, while trend temperature dominant SSH magnitude. Moreover, elevation correlated variability. The elevation-dependence become more pronounced years, high-heatwave migrating higher elevations. Furthermore, difference land cover type can affect intensity some extent. underscore patterns evolution around century provide scientific basis for interaction between different periods.
