格尔木太阳辐射与气温的多年变化

利用格尔木１９５６～１９９４年的气温和太阳总辐射资料，分析了该地区太阳总辐射和气温的多年变化特征及其相关关系。结果表明：３０多年中该地区太阳总辐射没有明显的减少趋势；年平均气温６０年代为低值，７０年代迅速上升，比东部平原地区提前，且呈现“冬暧夏凉”的变化趋势；７０年代至９０年代年平均气温与太阳总辐射呈现滞后一年的正相关；夏季气温与同期太阳总辐射有很好的正相关，但冬季的气温变化则与太阳总辐射呈负相关

SECULAR VARIATION CHARACTERISTICS OF SOLAR RADIATION AND AIR TEMPERATURE AT GOLMUD

The secular variation characteristics and the relationship between global radiation and air temperature are analysed by using the data of air temperature and global radiation from 1956 to 1994 at Golmud. The results show that decreasing tendency of the global radiation is non-obvious in 37 years. The annual mean air temperature is low in the 1960's, it rapidly increases in the 1970's and early appears about 10 years than that in eastern plain. There is a tendency of warming in winter and cooling in summer. The relationship between annual mean air temperature and global radiation is positive correlation of delay one year from the 1970's to 1990's. The relationship between the air temperature and global radiation for the same period is positive correlation in summer and is negative correlation in winter.
