Short summary
Annual air temperature spiked and glacier retreated shortly before the three periglacial debris flows in Tianmo valley. However, they did not occur when glacier retreat was sharpest, resulting from the frozen bared glacial till as the melting of internal ice lags behind glacial retreat. The activity of the glacial till can be enhanced by prolonged high air temperature. Finally, either rainfall or continuous percolation of ice ablation water flows can generate debris flow.
