福建省5级地震的气候前兆

本文通过相关统计事实,初步探讨了福建5级地震前期的气象异常,提出了“气压、气温和雨量”模式,发现一次中强震前的1～3a间,先出现大面积降压和最高气温的异常增温,后出现大面积的干旱。这一时序演变,似可作为一次完整的孕震过程的气象前兆而用于中长期地震预报。

Climatic indications of M 5 earthquake in Fujian

Based on the meteorological abnormalities before an earthquake, this paper studies the relationship between meterology and earthquake and puts forward that an earthquake has its indications in air pressure, air temperature and rain. It is concluded that there would occur in series of large-scale pressuredrop and abnormal rise of extreme high air temperature and then large-scale drought one to three a before a M 5 earthquake. This temperal evolution may be regarded as a climatic indication of earthquake and be used for earthquake prediction.
