Effect of Urbanization on Surface Air Temperature Trends over Northern Xinjiang
Based on the temperature reference station data set and analysis method developed in the previous research,the trend variation characteristics of the surface temperature series recorded by the base station,reference stations and four representative urban stations in northern Xinjiang were compared and analyzed,and the possible reasons for the particularity of urbanization in the temperature series of urban station in northern Xinjiang were discussed.The results show that,compared with other regions in China,the impact of urbanization of urban stations and references stations shows a significant negative trend of temperature.This paper examines the peculiarity in urbanization effect of northern Xinjiang as found in previous studies.The annual mean urbanization effect at the national stations reaches-0.05℃/10 a,and the urbanization contribution is-14.1%.The urbanization effects in spring,summer,and autumn shows a significant negative trend,with that of autumn being the most significant.The urbanization effect in winter shows an insignificant positive trend.The annual mean urbanization effect at the four urban stations of Wusu,Shihezi,Karamay and Urumqi ranges from-0.07 to-0.19℃/10 a,and the urbanization contributions ranges from-23.3%to-100%.The analysis results of this article contribute to a deeper understanding of the particularity and possible reasons of the urbanization effect in arid areas,and have certain reference significance for detection and attribution of regional climate change.
