摘要

厄尔尼诺或南方涛动是热带海洋与大气强烈耦合和相互作用的结果，对全球气候系统的发展起着重要作用。本研究以泰米尔纳德邦的月降雨量数据集和59年(1950 - 2008)的尼诺3.4海温数据集为数据集，通过干预分析，模拟和分析了厄尔尼诺事件对泰米尔纳德邦年降雨量的影响。实验结果表明，ARIMA - Intervention模型能够更准确地解释和分析干预事件的影响。

El Nino based intervention analysis of Rainfall in Tamilnadu

The El Nino or Southern Oscillation is the outcome of the strong coupling and interactions between the Tropical Ocean and Atmosphere, which plays a major role in the development of global climatic system. In this study, a data set containing the Monthly Rainfall in Tamilnadu and a data set containing the Sea Surface Temperature of Nino 3.4 for 59 years (1950 – 2008) are used to model and analyse the impact of El Nino events in the Annual Rainfall of Tamilnadu through Intervention analysis. The experimental results show that the ARIMA - Intervention model is more precise in explaining and analysing the effect of Intervention events.
