The impact of NSCAT winds on predicting the 1997/1998 El Niño: A case study with the Lamont‐Doherty Earth Observatory model

Using the NASA scatterometer (NSCAT) winds for initialization has greatly improved the Lamont‐Doherty Earth Observatory model forecasts of the 1997/1998 E1 Niño. The improvement is mostly attributed to the better resolved wind field in the southeast tropical Pacific. Because of the simplicity of the model and the short record of the NSCAT data, our model results should be taken as indicative rather than conclusive. Nevertheless, it is crucial to assimilate accurate information into the initial model state to predict the development of E1 Niño. Satellite‐derived wind products certainly have the potential to provide such information for real‐time forecasting.
