| Abstract: | The great gorge of Yarlung Zangbo river is a hot|spot over earth has been proved by the gravity, geomagnetic, geological, geothermal heat and atmospheric data. Some substances often surge from mantle to the earth surface, which process is not constant and has obvious pulse, characterized by ground temperature over hot|spot region where is a apparent positive relation in correlation map of the variations of Zedang's temperature (at 3 2m) in stations over China from 1965 to 1992. It can bring more precipitation here. Out of from the hot spot, there are positive and negative axes around the hot|spot and to arrange in circular waves with same distance. The average distant of the axes is about 820km, which prove the pulse propagation would infect the distribution of summer precipitation in China. In the hot|spot region, the geothermal heat pulse propagation has preference direction. So, it has obvious contribution for summer precipitation in South Ch ina. |
