| 摘 要： | 统计分析了半个世纪以来，气候变冷区域青藏高原东侧地区云，日照，温度和日较差的变化及相互关系。结果表明，青藏高原东侧地区气候变化具有显著的区域特征,总云量与日照比全国平均情况有更密切的反相关系，并且都与日较差有很好的线性相关。在春，夏季，它们都与温度有，但秋，冬季相关不明显。最后指出了云和日照可能是青藏高原东侧地区春，夏季温度变化的重要原因，而秋，冬季则与亚洲范围大气环流及青藏高原影响等有关。

| Abstract: | The variations and interrelations of the cloudiness, sunshine, temperature and daily range of the cooling region on the eastern side of Qinghai Xizang Plateau are statistically analyzed during the last half century. It is obtained that the climate change has obviously regional characteristics on the eastern side of Qinghai Xizang Plateau. The total cloudiness and sunshine have closer opposite relation than that of China. Both have well linear correlation with daily range and have closely correlation with temperature in spring and summer, but do not in autumn and winter. Finally, it is pointed out that the cloudiness and sunshine are possibly important reasons for the variation of temperature on the eastern side of Qinghai Xizang Plateau in spring and summer. But in autumn and winter, the variation of temperature is connected with the general circulation in Asia and the influences of Qinghai Xizang Plateau. |
