摘要
用Ｐ－σ混合坐标系五层原始方程模式，模拟了１９９１年７月１－２日长江中下游地区的暴雨过程，并就不同海域海表温度异常对此次降水过程的影响进行了数值试验。结果表明，当海表温度发生异常时，环流形势在短期（２－３天）内就有所变化，降水也受到一定程度的影响。
By employing a P σincorporated coordinate model with five layer primitive equations, the rainstorm of the middle and lower Yangtze River of July 1-2, 1991 has been simulated. And three numerical experiments with sea surface temperature anomalies of different sea areas have been carried out to investigate the effect on this rainstorm.The results show that the atmospheric circulation and precipitation could be changed somewhat in short term(2-3 days) by the sea surface temperature anomalies.
