针对低能见度天气的危害性，运用信息数字方法发现了霾的发生、发展与地热的联系和大气结构特征的改变。霾的预测、预防，需要正确把握近地低空大气的滚流状态和热结构特征。霾的形成既有人为排放也有自然界地热引发地下污染物和污浊气体的释放问题，地热可作为霾天气预报的先兆信息。大气环境的改善，需要人们改进排放技术，也需要研究自然污染源问题。

Aimed at the harmfulness of low visibility weather， using digital information method found the relationship between occurrence， development of haze and geothermal， and the change of atmospheric structure characteristics. Prediction and precaution of haze need to correctly grasp tumble state of the lower atmosphere near the earth and thermal structural features. The formation of haze both has anthropogenic emissions also has the release of underground pollutants and dirty gas caused by natural geothermal. And geothermal can be taken as premonitory information of haze weather forecast. To improve the atmospheric environment， people need to improve emissions technology， also need to study the natural sources of pollution problems.
