低温降水对未来强震的指示意义

本文列举震前低温降水与强震相对应的案例。指出这种对应关系的内在机制是:震前地壳内应力增强裂隙增多,使地下气体大量逸出,大气中气溶胶浓度增大;从诱发寒潮,反射、吸收太阳入射辐射、改变云层性质及作为水蒸气凝结核造成降水等方面导致低温。

Cooling-Snowing & Aerosol Increasing before Strong Earthquakes

The article listed the cases in which low temperature and snow falling were followed by strong earthquakes.Research shows that the mechanisms of the correspondence are that the escaping of large amount of underground gas from the Earth surface caused the growing in number of aerosol raised into the atmosphere because of the increasing of micro-fractures in the crust before earthquakes.The underground gas escaping may induce a cold wave;the aerosol would reflect and absorb the radiation of the Sun,increase the reflection of clouds as well as coagulate water vapors to precipitate(in case vapors are plentiful);so temperature gone down.
