低平流层温度对银河系宇宙线强度变化的响应

RESPONSE OF THE LOWER STRATOSPHERIC TEMPERATURE TO VARIATIONS OF THE GALACTIC COSMIC RAYS INTENSITY

选用芬兰中子堆监测站从ｌｏｐ年７月至１９８９年３月的宇宙线强度月平均曲线数据，和在相对应期间我国境内海拉尔等４个高空气象观测站的３０ｈＰａ和１００ｈＰａ等位势高度上常规气温观测月平均资料，经统计分析，取得初步结果：低平流层气温与银河系宇宙线辐射强度之间呈现负相关的特性；与银河系宇宙线辐射强度峰区和谷区相对应会在低平流层中引起幅值为２—３℃的温度变化；不同纬度观测站所得观测数据表明，上述增温幅值随纬度降低而减少．

In this paper,the galactic cosmic ray(GCR)intensity observed by neutron moritor at Oulu.Finland for three succesive solar minima and meteorological data at 30 and 100hpa form 4 Chinese stations are used to find the correlations between GCR intensity and lower stratospheric temperature,The results show a negative correlation, the temperature changes 2℃ to 3℃ between GCR intensity maxima and minima.The magnetued of this chang decreasing as latitudes lowering.
