| 摘要 | The diurnal temperature range (DTR) is considered a signature of observed climate change, which is defined as the difference between the maximum (T-max) and minimum temperatures (T-min). It is well known that the warming rate of mean temperature is larger at high elevations than at low elevations in northeast China. However, it is still uncertain whether DTR trend is greater at high elevations. This study examined the spatiotemporal variation in DTR and its relationship with elevation in northeast China based on data from 68 meteorological stations from 1961 to 2015. The results show that there was a significant declining trend (0.252 degrees C/decade) in DTR from 1961 to 2015 due to the fact that T-min increased at a faster rate than T-max. Seasonally, DTR in northeast China showed a decreasing trend with the largest decrease rate in spring (-0.3167 degrees C/decade) and the smallest decrease rate in summer (-0.1725 degrees C/decade). The results of correlation analysis show that there was a significant positive correlation between the annual DTR trend and elevation in northeast China. This is due to the fact that increasing elevation has a significant warming effect on T-max. Seasonally, there were significant positive correlations between the DTR trend and elevation in all seasons. The elevation gradient of DTR trend was the greatest in winter (0.392 degrees C/decade/km) and the lowest in autumn (0.209 degrees C/decade/km). In spring, summer, and autumn, increasing elevation has a significant warming effect on T-max, leading to a significant increase of the DTR trend with increasing elevation. However, in winter, increasing elevation has a significant cooling effect on T-min, resulting in a significant increase of the DTR trend with increasing elevation. |
