运用中华传统文化的整体思维和现代统计学、气象学、地震学原理，发现特大暴雨、台风突变和大地震临震、火山爆发等突发性特大自然灾害(均为当前公认的世界性科学难点)，都是在内部条件基本具备情况下，由月亮为主的“三星一线”时的引潮力共振异常叠加而触发。用此种内外因耦合方法预测特大暴雨和大地震临震，成功率分别为727%和40%。提出了“三星一线”时是否存在引力放大和电磁力放大的系列观测实验和研制特大暴雨数值预报模式的方案。

Applying the traditional Chinese whole view thought and the principles of the modern statistics, meteorology and seismology, it is found that most natural disasters of a sudden (include the extraordinary rainstorm, typhoon sudden change, impending violent earthquake,volcanic eruption, etc. ) are triggered by tide-generating force resonance at collinearity of three stars when the internal conditions are satisfied. Using the internal-external cause coupling method to predict extraordinary rainstorms and impending violent earthquakes, the success rate is respectively about 72.7 % and 40 % . This study program include serie observation experiments to test whether there exist amplifications of the gravitational force and the electromagnetic force at the time of collinearity of three stars and sets up the forecasting mode of extraordinary rainstorm.
