| 摘 要： | 利用青海玉树国家基本气象观测站1961-2010年的总辐射常规观测资料, 分析了玉树地区总辐射的长期变化趋势. 结果表明: 玉树地区总辐射在1961-2010年期间总体呈现减弱趋势, 其变化经历了增强变"亮"-减弱变"暗"-增强变"亮"-震荡回落4个阶段; 春、夏季的总辐射变化趋势对年际变化趋势有主导作用. 小波分析表明, 玉树地区近50 a的总辐射变化过程中, 存在多时间尺度周期的变化特征; 长期变化趋势和国内其他站点的变化趋势相比均表现出减弱的趋势, 但各站点减弱趋势倾向率不同. 最后, 对比分析了总辐射和同期气象要素、MODIS反演的气溶胶AOD之间的关系.

| Abstract: | Based on the surface radiation data at Yushu station from 1961 to 2010, the secular variation of solar radiation was analyzed. The result shows that the trend of secular variation of solar radiation over Yushu region from 1961 to 2010 was gradually declining. The long term variation of solar radiation was experienced four phase: "brightening", "dimming", "brightening" and "declining". The inter-annual variation was mainly determined by the variations of spring and summer. The wavelet analysis showed there are multiple time scale periods in the solar radiation sequence during the past 50 a. Compared with other stations in China, the long term variation of solar radiation showed the same declining trend, but the climatic trend rates are not as well as Yushu. The relationships between solar radiation and meteorological elements、aerosol optical depth (AOD) were also briefly analyzed. |
