Abstract: By using 541-station uniform maximum temperature in China, the temporal and spatial distributions of yearly high temperature days with daily maximum temperature ≥35℃ and their responses to global warming were analyzed. The results show that the average high temperature days have two high centers in Turpan Basin and Jiangnan region. The high temperature days have an evolutional trend of increasing-decreasing-increasing and show the significant 3-year period in Xinjiang and the 3- to 6-year period in the 4 regions of eastern China. The time of trend changing from decreasing to increasing is not synchronous for the whole country, and it gets later with the increasing latitude.

Key words: high temperature days, global warming, regional response
