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.
