中文摘要	利用格尔木大型光伏电站内外空气温湿度观测资料,比较站内外气温与空气相对湿度的日变化与年变化特征,分析造成光伏电站内外空气温湿度差异的可能原因。结果显示:对2m气温而言,冬季白天,站内外基本相同;春、夏、秋季白天站内明显高于站外,夏季差异达最大,为0.67 ℃,这与太阳电池板发热,加热空气的效应大于光伏板的遮阳冷却效应有关;而在四季夜晚,站内2 m气温值均高于站外,这可能与光伏板对近地面层的保温作用有关。而10 m气温,四季白天站内均低于站外,其中秋、冬季相差较大,这可能与冬、夏气温对太阳电池板光电转换效率的影响,进而造成10 m处能量收支差异有关;夜晚表现为站内低于站外,这可能与白天站内外地表能量收支差异有关。在年变化中,站内2m气温月均值均高于站外,站内10m气温月均值均低于站外。在10m高度处,夜晚站内空气相对湿度大于站外。
英文摘要	Based on the air temperature and humidity observation data in the large solar farm and the region without PV array in Golmud,this study compared the mean diurnal and annual variation features of the air temperature and humidity in the two sites,and tried to understand the cause of the differences,i.e. the climate effect of the PV farm. The results show that air temperature at height of 2 m in the two sites are basically the same in winter daytime,but in the other seasons,the daytime air temperature in the PV farm is higher than that in the region without PV farm,the maximum difference appears in the summer daytime,which is 0.67 ℃,the reason is that the solar panels radiate heat during the daytime,and its effect of heating the air is greater than the shade cooling effect. The nighttime air temperature at height of 2 m in four seasons in the solar farm are higher than that in the region without PV arrays since the solar panels have heat preservation effect near the ground. The daytime air temperature at height of 10m in four seasons in the solar farm are lower than that in the region without PV arrays,the larger difference value appear in autumn and winter,because the air temperatures in winter and in summer make different power conversion efficiencies of photovoltaic panels,thus causing energy budget different at height of 10 m in the two sites. The nighttime air temperature at height of 10 m in the solar farm are lower than that in the region without PV array since the surface energy budgets are different during the daytime in the two sites. Monthly average air temperature at height of 2 m in solar farm is higher than that in the region without PV array and monthly average air temperature at height of 10 m in the farm is lower than that in the region outside the farm. The nighttime air relative humidity at height of 10 m increased in the PV farm.
