摘要
本文根据广州1961-2002年历年各月的总辐射、直接辐射、散射辐射和日照百分率资料,采用最小二乘法拟合太阳辐射总量计算公式经验系数ao、bo以及散射辐射总量经验计算公式经验系数ao、bo,得到广东省不同方位变倾角倾斜面上月太阳辐射总量的气候学经验计算公式。同时结合广东省各县市气象站累年各月的日照百分率资料,以45°倾角为例,分析了广东省东、西、南、北四个朝向的倾斜面上太阳辐射总量的年月分布特征。
In this paper, an empirical formula calculating monthly total solar radiations on slopes with different directions is formulated based on the Fine Weather Model. With the monthly data of total solar radiation, incident radiation, scattered radiation and percentage of sunshine from 1961 to 2002 in Guangzhou,least square fitting methods are used to fit the empirical coefficients in the formula of total solar radiation and scattered radiation which was developed by Angstrom and Anderson. And the climatological formula for monthly total solar radiations on slopes at any angles and any directions in Guangdong was obtained. Furthermore, based on the empirical formula and the sunshine percentage over weather stations in Guangdong, taking the slopes with 450 angle facing south, north, east and west, respectively, as examples, the monthly and yearly total solar radiations in all parts of the province are calculated, and their spatial and temporal characteristics are analyzed.
