摘要

摘要: 根据本文定义的中太平洋纬向风辐散辐合指数, 初步揭示了中部型El Nino事件的形成机理。结果表明, 纬向风异常的辐散辐合是中部型El Nino事件形成的关键过程。由相关分析表明, 中太平洋纬向风辐散辐合和中部型事件之间存在显著的时滞相关关系。中太平洋纬向风辐散辐合指数可以用来预测中部型事件的发生。在此结果的基础上, 建立了一个一元线性回归方程, 该方程可以提前5个月对中部型事件进行预测。

Abstract: The central Pacific (CP) zonal wind divergence and convergence indices are defined, and the forming mechanism of CP El Niño (La Niña) events is discussed preliminarily. The results show that the divergence and convergence of the zonal wind anomaly (ZWA) are the key process in the forming of CP El Niño (La Niña) events. A correlation analysis between the central Pacific zonal wind divergence and convergence indices and central Pacific El Niño indices indicates that there is a remarkable lag correlation between them. The central Pacific zonal wind divergence and convergence indices can be used to predict the CP events. Based on these results, a linear regression equation is obtained to predict the CP El Niño (La Niña) events 5 months ahead.
