英文摘要	Extreme climate events have exerted strong effects on permafrost environments over the past few decades. The occurrence of extreme warming events during the cold season can alter the hydrothermal dynamics of the active layer. Here, we used meteorological and observational soil hydrothermal data to investigate variations in extreme warming events and their impacts on the hydrothermal regimes of the active layer in three permafrost regions in China. The results indicated that the eight analyzed extreme warming indices showed statistically significant increasing trends with differing rates from 1962 to 2019. Prominent differences existed in the mean values and linear trend magnitudes not only among the three permafrost regions but also among the eight indices. Most recorded high-intensity extreme warming events occurred primarily in the past 15 years (2005-2019). The occurrence times of extreme events and the active layer freeze-thaw process codetermined the influential extents of the extreme events on the active layer hydrothermal conditions at the Tanggula permafrost Monitoring Site. Events that occurred from March to April could cause soil temperature to increase with a greater magnitude than that induced by events occurring from October to November. Different event types could also lead to distinct differences in their corresponding influential extents. [GRAPHICS] .
