Abstract:
The variation characteristic of sunshine duration over Black Gobi Desert of China was analyzed on the basis of monthly sun- shine duration series (1960 -2011) from 11 surface meteorological stations. The results indicated that although sunshine duration was decreasing markedly in most parts of China,in Black Gobi Desert,the variation of sunshine duration was steady and showed an insig- nificant trend with a decreasing rate of -2. 0 h/10 a in recent 52 years,which was much less than that of surrounding areas. Among the four seasons,the sunshine duration showed an increasing tendency with a rate of 0. 34 h/10 a in spring,but a negative trend oc- curred in other seasons,especially in winter,the decreasing trend was significant with a rate of -3. 04 h/10 a. For different regions, annual sunshine hours variation was not the same,in the northern foot of the Tianshan Mountains and the western Qilian Mountains and the parts of west side of Alxa Plateau,the sunshine duration showed an decreasing tendency,but in the Hami basin,Dunhuang basin and most parts of Beishan,it showed an increasing tendency. The decrease of sunshine hours in Black Gobi Desert was closely related to obvious increase of annual precipitation and decrease of annual mean wind speed there.
Key words: Black Gobi Desert, sunshine duration, trend, abrupt change, influence factor
摘要:
利用 1960 ~2011 年中国黑戈壁地区 11 个气象站日照时数数据,分析了该地区日照多年变化特征。研究表明,该地区近 52 a 来日照时数减少的变化并不明显,其趋势变化率为 -2. 0 h/10 a,远小于周边地区。四季之中,春季日照时数呈增加趋势,其他三季呈减少趋势。从空间分布上看,不同区域,年日照时数变化也不相同。黑戈壁地区年日照时数的减少与年降水量的显著增加和年平均风速的减小密切相关。
