摘要:
[Objective] The aim was to analyze diurnal temperature range in Guigang from 1960 to 2009.[Method] Based on the conventional meteorological data(mean daily temperature,mean maximum temperature,and mean minimum temperature) of Guigang region during 1960-2009,the Diurnal Temperature Range(DTR) and the DTR trend were studied.[Result] The annual minimum temperatures and the annual maximum temperature were significantly increasing.The maximum temperature rose less than minimum temperature and spatial changes of daily temperature narrowed gradually from the Tropic of Cancer to the two sides.The extreme diurnal temperature decreased mostly in stations far away from the Tropic of Cancer and the significance was strong.The extreme diurnal temperature decreased little in stations close to the Tropic of Cancer.Influences of different factors on daily difference varied.DTR positively correlated with sunshine duration,and negatively related to total cloudiness,relative humidity and precipitation.DTR had insignificant relation with average wind speed.[Conclusion] The study provided basis for the understanding of climate changes in Guigang.
