西北地区太阳总辐射的气候学计算及分布特征
Climatological Calculation of Total Solar Radiation and Its Distribution Characteristics in Northwest China
摘要
Abstract
Based on the observation data of 25 insolation stations and the data of sunshine percentage from 163 conventional meteorological stations in Northwest China during 1960-2009, the estimated formula of total solar radiation was established by using the percentage of sunshine to calculate the total solar radiation in Northwest China and discuss the spacial distribution characteristics. The results indicated that the annual amount of total solar radiation in Northwest China from 1960 to 2009 presented the spacial distrib ution characteristics of low on both sides and high in the middle. The high value area was located in Qaidam Basin area, Eastern Xinjiang and the junction areas of Qinhai, Xinjiang and Gansu in Western Gansu, and the maximum value was in Geermu and Qinghai. Two low-value areas were located in Shaanxi and the south areas of Gansu and Tianshan areas of Xinjiang. The minimum value was in Ankang, Shanxi. From the spatial distribution every month,it indicated that the location of the high-value area in the central areas and the low-value area in the west of Northwest China changed obviously, especially in the central high-value areas, there were the obvious characteristics, such as, moving northward and back from southward;however, the location of the low-value area had not obvious changes.关键词
