摘要
利用新疆乌鲁木齐市日射站1960-2005年的逐日太阳总辐射、日照时数、低云量和水汽压等资料,采用常规统计方法,分析乌鲁木齐市太阳总辐射的时间变化特征并分析其原因;在太阳总辐射气候学计算原理的基础上,采用线性回归方法建立各月的总辐射计算公式,根据回归误差分析和相关系数检验,确定适合乌鲁木齐市的月太阳总辐射气候学推算公式,进而计算全区各站点逐月太阳总辐射通量,分析新疆地区四季太阳总辐射空间分布特征.结果表明,新疆地区太阳总辐射7月达到最大值,而太阳总辐射最小值一致出现在12月份;各季节的太阳总辐射以夏季最大,其次为春季、秋季、冬季.新疆地区年太阳总辐射和各季节太阳总辐射均呈现逐年下降的趋势,这是由于日照时数减少,低云量增大引起的.新疆地区四季太阳总辐射总体呈现北低南高的空间分布格局.
Abstract
Bascd on the daily solar radiation,daily sunshine hours,low cloud and water vapor pressure data of Urumqi Meteorological Station during 1960-2005,the temporal variation characteristics of total solar radiation in Urumqi were analyzed by the conventional statistical method.On the basis of the climatological calculation formula of solar radiation,using the linear regression method to establish the formula for calculating the total radiation in each month,which determined the suitable climatological formula for monthly solar radiation for Urumqi City by the regression error analysis and correlation coefficient test.Therefore,the ground solar radiation flux was calculated form month to month,and the spatial distribution characteristics of the solar radiation in the four seasons in Xinjiang were analyzed.The results showed that the total solar radiation in Xinjiang reached its maximum value in July,and the minimum value of total solar radiation was consistent with that in December.The total solar radiation in each season was the largest in summer,followed by spring,autumn and winter.The trend of annual and seasonal total solar radiation were decreased,which was due to the decrease of sunshine duration and the increase of low cloud amount.The spatial distribution pattern of the total solar radiation in the four seasons showed Northern lower than southern.
