Time-Series Embeddings from Language Models:A Tool for Wind Direction Nowcasting

扫码查看
Wind direction nowcasting is crucial in various sectors,particularly for ensuring aviation operations and safety.In this context,the TELMo(Time-series Embeddings from Language Models)model,a sophisticated deep learning ar-chitecture,has been introduced in this work for enhanced wind-direction nowcasting.Developed by using three years of data from multiple stations in the complex terrain of an international airport,TELMo incorporates the horizontal u(east-west)and v(north-south)wind components to significantly reduce forecasting errors.On a day with high wind direction variability,TELMo achieved mean absolute error values of 5.66 for 2-min,10.59 for 10-min,and 14.79 for 20-min forecasts,processed within a swift 9-ms/step timeframe.Standard degree-based analysis,in comparison,yiel-ded lower performance,emphasizing the effectiveness of the u and v components.In contrast,a Vanilla neural net-work,representing a shallow-learning approach,underperformed in all analyses,highlighting the superiority of deep learning methodologies in wind direction nowcasting.TELMo is an efficient model,capable of accurately forecast-ing wind direction for air traffic operations,with an error less than 20° in 97.49%of the predictions,aligning with re-commended international thresholds.This model design enables its applicability across various geographical loca-tions,making it a versatile tool in global aviation meteorology.
