地球自转与东北地区夏季温度变化

RELATIONSHIP BETWEEN EARTH ROTATION SPEED AND TEMPERATURE OF NORTHEAST CHINA IN SUMMER

摘要: 该文研究了东北地区夏季温度与地球自转速度变化的关系.得到:地球自转减慢时东北温度偏低, 当自转年变量ΔU≤-22时出现典型的低温冷害年; 自转加快时东北温度偏高.东北地区夏季温度与极移振幅的位相也有较好的关系:在极移振幅的峰值年附近容易发生冷夏年, 在极移振幅的谷值年附近容易发生热夏年.

Abstract: The relationship between temperature of Northeast China in summer and the earth rotation speed is studied. The results indicate that temperature of Northeast China is lower when earth rotation speed decreases and higher when earth rotation speed increases. The temperature of Northeast China in summer has also relevance to the phases of amplitude of polar motion.
