Abstract:Anomalous change of some meteorological factors had taken place before the great earthquake of Ms=7.4 Occurred in Wuqia at 20 o'clock on August 23, 1985. Doing a statistical calculation of the meteorological data accumnlated over the years in Wugia and the neighbonring zones and comparing the obtained results, We discovered that the anomalies of the rainfall, and temperature, atmospheric pressure and temperature which had occurred before the earthquake in the central zone of earthquake were very apparent, and the earthquake epicentre is corresponding to the anomalous centre. This declares that some internal relations between meteorological phenomenons and earthquake exist really, so we think that the moterological factors can play a part in the earthquake forecast with a method of combining the meteorolocal factors with other measures.
