| 摘 要： | 本文根据时空谱分析方法，对照分析了长江上游汛期（６～９月）丰水年（１９５４年）和枯水年（１９７２年）５００ｈＰａ，上准静止波，瞬变波能量，以及表现瞬变波的驻波和移动波（包括东进波和西退波）。结果表明，所有这些波动能量的时空分布在丰水年和枯水年均在显著性差异。

| Abstract: | On the basis of the space-time spectral analysis method, the paper compares with analysing the features of various atmospheric fluctuations on 500hPa as the plenty (1954) or deficiency(1972) discharge of the upper reaches of the Changjiang River in flood period (Jun. to Sep.),and obtains some significant information. The analytic results show that the features of space-time distributions between the various fluctuations of plenty and dificiency discharge year are obviously different. |
