| 摘要: |
| 通过对气候标准值从1961~1990年改为1971-2000年后ENSO指数的变化分析,确定了新指数的ENSO事件定义指标和强度划分指标,重新定义了1951~2003年的ENSO事件及事件强度,并对新旧指数定义的ENSO事件的长度、峰值、强度等进行了分析比较。 |

| Abstract: |
| Through studying changes in ENSO indices relative to change of climate reference from 1961~1990 to 1971~2000, we generated new standards to define ENSO episode and its intensity. Then according to the new climate references and new index standards, ENSO episodes and their intensities for 1951~2003 have been classified. Finally, an analysis has been performed comparing the old and new ENSO durations,peak values and intensities. |
| Key words: change of climate reference ENSO episodes indicators |
