NAO and jet indices

This fileset provides the seasonal NAO indices and the jet latitude and jet speed indices for the ERA-Interim and ERA-20C reanalyses, and the ASF-20C, SEAS5 and GloSEA5 (CS3) seasonal re-forecasts. The methodology is described in the article "Seasonal predictability of the winter North Atlantic Oscillation from a jet stream perspective".

本数据集文件集提供了ERA-Interim、ERA-20C再分析资料，以及ASF-20C、SEAS5和GloSEA5 (CS3)季节再预报试验的季节北大西洋涛动（North Atlantic Oscillation, NAO）指数、急流纬度指数与急流风速指数。该数据集所用的研究方法详见论文《从急流视角探讨冬季北大西洋涛动的季节可预报性》。
