| 摘要: |
| 对近十年出现的3个厄尔尼诺年和2个反厄尔尼诺年中4—10月的夏季热带平均流场及几个主要系统作了定量综合分析和对比,得到:它们的沃克环流和哈得莱环流、对流层低层ITCZ和对流层高层TUTT的位置以及40—50°E、145°155°E处的低层越赤道气流强度均和常年不同,它们各自的年际和月际之间的平均环流和主要系统的特征也有差别。 |

| Abstract: |
| The features of mean tropical flow fields and a few major systems are quantitatively and compositely analysed and the results compared for the summertime in three El Nino years and two anti-El Nino years in the past ten years. It is shown that the walker cell and Hadley Cell, the positions of FTCZ at lower levels and TUTT at upper levels, the cross equatorial flow intensity at 40-50°E and 145-155°E, are respectively different from their own averages. Difference is also found within the circulation and individual systems in terms of their averages from year to year and from month to month. |
