基于创建的行星会合指数运动学方程，获得了太阳绕太阳系质心的运动周期为准22年.太阳轨道运动周期和北半球高空大气温度场准22年变化周期二者具有极大的相关性.在整个太阳系角动量守恒的前提下，得到太阳轨道角动量和太阳自转角动量之和守恒.理论上，通过太阳绕转和自转角动量间的转换，建立了行星会合指数与全球高层大气温度场变化的对应关系，进而在大气温度场变化与太阳活动之间建立了联系，并对全球气候变化的成因机制进行了新的探索.

英文摘要：

The kinematics equation of the planetary synodic index was created, and based on it, a cycle of 22-year was determined for Sun motion round the mass center of the solar system. This period is highly correlated to the 22-year cycle of the upper atmospheric temperature of the northern hemisphere. On the premise of the conservation of angular momentum in the whole solar system, the sum of angular momentums between Sun motion round the center of solar system and solar rotation is conservative. Through their transformation between the angular momentums between Sun motion round the center of solar system and solar rotation, we found the corresponding relations between the planet juncture index and variation of the upper atmospheric temperature of Earth. In addition, we studied the relations between the upper atmospheric temperature change and the solar activity, and discussed the genetic mechanism of global climate change.
