| 摘 要： | 简要介绍了近十多年来地气相互作用研究领域所取得的成果,并从整体地球系统的角度探索自然灾害(气象灾害和地震灾害)的成因.在总结和评述过去工作的基础上,提出了地幔对流节律性假说,并利用这一假说解释了板缘地震、地球自转和厄尼诺之间的关系;利用地幔中存在中小尺度对流这一设想并结合绝对涡度守恒原理讨论了板内地震、地热流和旱涝分布之间的联系.最后提出了对今后地气耦合研究工作的一些看法.

| Abstract: | Advances in the interaction between the Earth and the atmosphere during recent 10 years are brieflyintroduced and the causes of natural disasters(include meteorological disaster and seismic disaster)are ex-plored from the point of view of earth system in this paper.Based on concluding and reviewing the studieson earth-atmosphere coupling,before,a hypothesis of mantle convection rhythm is put forward and thehypothesis is used to explain relationships between plate-boundary earthquake,earth rotation and ELNino;a hypothesis of microscale and mesoscale convection occurring in the mantle and principle of con-servation of absolute votticity are used for discussing relationships between intraplate earthquake,geothermal flow and distribution of drought and water-logging.In the last section of the paper,someviews about studies on earth-atmosphere coupling in the future are given. |
