Abstract Using the air temperature data of the National Center for Environmental Prediction (NCEP), we compared multiple layers of air temperature differences before, during and after the Jiujiang earthquake, and explored its relationship with the additive tectonic stress caused by celestial tide-generating force (ATSCTF). The earthquake occurred at the 1 of 4 high phases of ATSCTF, while the temperature rise came from land surface to high sky. It indicated that the tide force could trigger an earthquake when the tectonic stress was in critical status, and the air temperature rise reflected the terra stress change modulated under the tidal force. During the shock period of ATSCTF, the distribution of air temperature changes both near land surfaces and upper multi-layers along the active fault zones showed a tectonic disturbance pattern of calm before earthquake, rise during earthquake, calm after earthquake as well as a heat distribution pattern of the surface air warmed by land, uplifted by heat flux, cooled and dissipated in the sky. The pattern of changes obeyed the rule of thermal rise of rocks broken under stress loading and the principle of atmospheric thermal dynamic diffusion in vertical. We argued that an earthquake may also be a reason for air temperature differences rather than a simple weather process. At the same time, the rise of air temperature was synchronized with the ATSCTF fluctuant, which showed that tidal force had a particular indicative significance for the identification of temperature anomaly on seismic faults. Because of the mechanical characteristics of the study of earthquake thermal anomalies, it could help to identify the earthquake thermal anomalies and the climatic thermal anomalies, and provided a clear time-indication for the choice of the background temperature in the seismic thermal anomaly recognition.

九江地震前后多层气温差异对潮汐力和构造应力的影响

摘要 利用国家环境预报中心(NCEP)的气温数据,对比了九江地震前、中、后的多层气温差异,探讨了其与天体潮汐力引起的附加构造应力的关系。 (ATSCTF)。地震发生在ATSCTF 4个高位中的1个,而温升则是从地表到高空。表明当构造应力处于临界状态时,潮汐力可以引发地震,气温上升反映了潮汐力调制下的地应力变化。在 ATSCTF 的冲击期间,沿活动断裂带近地表和上层多层气温变化的分布呈现震前平静、震中上升、震后平静的构造扰动格局,并呈现出受高温影响的地表空气热量分布格局。陆地,被热通量抬升,冷却并消散在天空中。其变化规律遵循应力载荷作用下破碎岩石的热升规律和大气热动力垂直扩散原理。我们认为地震也可能是导致气温差异的原因,而不是简单的天气过程。同时,气温上升与ATSCTF波动同步,表明潮汐力对于识别地震断层温度异常具有特殊的指示意义。由于地震热异常研究的力学特性,有助于识别地震热异常和气候热异常,为地震热异常识别中背景温度的选择提供明确的时间指示。
