| 摘 要： | 选取当地1955~2004年春季3~5月降水资料,首先分析各年的降水概况,进而根据辽宁旱涝划分标准对当地旱涝进行划分,并通过小波分析方法进行周期分析,得出盘锦旱涝周期明显,具有5~6年和1~2年周期,最后对重度旱、涝年的500 hPa高度场距平合成图进行对比分析,旨在找出旱涝年的环流特点,以期为今后的旱涝状况预测提供科学依据。

| Abstract: | Annual general rainfall has been analyzed by using local data of spring precipitation from 1955 to 2004 and the flood and drought has been identified based on the standard of those in Liaoning province.Through analyzed by the measure of Molet waves,the results show that there is obvious flood and drought periods of 5～6 years and 1～2 years in Panjin.At last,contrasting the synthetical fig of anomaly height field in 500 hPa of severe dry and wet years,it is expected to find out the characters of circumfluence of dry and wet years in order to provide the science method to the forecast of flood and drought status. |
