By using a new monthly temperature dataset from 1961 to 2014 over China by 0.5°×0.5° spatial resolution, the variation of the air temperature during the global warming hiatus period (1998-2014) was analyzed. It is found that, during the global warming hiatus period, the increasing trend of the mean and maximum air temperature over China indeed shifted, however the increasing trend of minimum air temperature over China didn't ceased, but only slowed down. The decrease in heating rate was mainly caused by the cooling trend in winter. The analysis showed that the warming type of China changed:the temperature in northern China showed a decrease trend, the temperature showed a relatively strong increase trend in Tibetan Plateau and southwestern region. For the seasonal means, the warming trend was very notable in summer but relatively weak in winter. For the elements, the strongest increase trend of temperature was the minimum temperature.

Key words: global warming hiatus, air temperature, variation characteristics, homogenization, grid dataset
