本文提出了震前低层大气的增温原因,利用温度倾向方程,考虑了每一项加热因子。铅直速度项(对流项)的值为-8.6°/天(3日)、-3.8℃/天(4日),位于地面至970毫巴的薄层内,辐射项分别为+3.9℃/天、+3.3℃/天,水平输送项,+0.43℃/天,-0.8°/天,潜热项很小。感热项(下垫面感热通量)是从倾向方程中倒算出来的,似乎分别是7.4℃/天,3.8℃/天。然而平均气温的观测表明,在1—4日的一半时间内高于平均地温。它意味着一半时间内感热输送是从大气输向地面,感热的净输送为零。这个结果表明震前低层大气加热非常不同于传统方式(热传导、涡流扩散),它似乎与地气污染有关,是震前地下所逸放出来。
In this paper, the reasons for the warming of the lower atmosphere before the earthquake are proposed. By using the temperature propensity equation, every heating factor is considered. The vertical velocity term (convection term) was -8.6 ° / day (3rd day), -3.8 ° C / day (4th day), and was in the ground to 970 mbar with radiation terms of + 3.9 ° C / Day, +3.3 ℃ / day, the level of transport items, +0.43 ℃ / day, -0.8 ° / day, latent heat is very small. The sensible heat (underlying sensible heat flux) is calculated from the propensity equation and appears to be 7.4 ° C / day, 3.8 ° C / day, respectively. However, observations of the average temperature show that it is above average ground temperature in half the 1-4 days. It means that in half the time the sensible heat is delivered from the atmosphere to the ground and the net heat transfer is zero. This result shows that the heating of the lower atmosphere before the earthquake is very different from the traditional method (heat conduction and eddy current diffusion). It seems to be related to the pollution of the earth’s air and is released from the ground before the earthquake.
