摘要
本文以海城、乌恰地震为例分析了我国强震前特大干旱的大气环流特征.表明强地震前的气象异常是显著的,且大气环流相对于多年平均环流具有明显的干旱特征,从而揭示了地震与大气环流异常之间的相互联系,这对提高强地震中长期预测的准确率有一定实际意义.
In this paper,the meteorological anomaly,the circulation characteristies of most droughts beforeearthquake are analyzed in the northeast,and the northwest areas of China.It is shown that the meteo-rological anomaly is of significance before earthquake,and the circulation has significant drought fea-tures to annual mean circulation from 1951 to 1980 years.In addition,it is pointed out that there iscorrelation between earthquake and the circulation anomaly,this correlation is useful for raising accu-rate rate for midrange and long-term prediction of strong earthquake.
