赛什腾山和冷湖镇日照时数对比分析

Comparative Analysis of Sunshine Hours in Lenghu Saishiteng Mountain and Lenghu Town

利用冷湖赛什腾山和冷湖镇气象观测站日照资料,对冷湖赛什腾山和冷湖镇两站日照时数的季节、月变化特征及气象影响因子进行了分析。结果表明:两地日照时数存在明显的季节差异,具体季节表现有所不同,其中赛什腾山春秋日照时数多、冬夏日照时数少,日照百分率夏季最小、秋季最大;分月来看两地日照时数的月变化均表现出波折起伏的变化状况,出现了两个峰值,赛什腾山第一个峰值出现在5月、第二个峰值出现在10月;从影响气象因素来看,赛什腾山日照时数与水汽压、相对湿度、风速呈负相关。分析结果对认识该地区气候背景和太阳能资源状况、开展赛什腾山天文台天文观测具有一定的现实意义。

Based on the statistical data of sunshine hours in Lenghu Saishiteng Mountain and Lenghu Town meteorological observation stations, the seasonal and monthly variation characteristics and meteorological influencing factors of sunshine hours in Lenghu Saishiteng Mountain and Lenghu Town were analyzed. The results show that there are obvious seasonal differences in the sunshine hours between the two places, but the specific seasonal performances are different. In Saishiteng Mountain, the sunshine hours are the least in summer and winter, and the sunshine percentage decreases in spring and summer. The monthly variation of sunshine hours in the two places showed a fluctuating trend with two peaks. The first sunshine hours peak of Saishiteng Mountain appeared in May, and the second peak appeared in October. From the perspective of influencing factors, the sunshine duration of Saishiteng Mountain is negatively correlated with water vapor pressure, relative humidity and wind speed, but positively correlated with precipitation. The analysis results have a certain practical significance for understanding the climate background and solar energy resources in this region and for astronomical observations at Saishiteng Mountain.
