本文通过逐日气象资料,研究了近二十年来滇东地区12次地震(震级≥5)之前地面气温的变化。发现不少震例,震前震中区气温有升高的现象。这种局部温度异常(热晕),很可能与震前地下热能的逸出有关,但是,也应重视由天气系统热力作用所形成的增温背景。 Based on daily meteorological data, this paper studies the changes of ground air temperature before 12 earthquakes (≥5 in magnitude) in eastern Yunnan over the past two decades. Found a lot of earthquake cases, the epicenter temperature before the earthquake has increased the phenomenon of temperature. This local temperature anomaly (thermal halo) is probably related to the escape of subsurface heat prior to the earthquake, but attention should also be given to the warming background created by the thermodynamic effects of the weather system.
