论文摘要

能源的供求受气象条件的影响。随着对可再生能源的需求的增加,准确天气预测的相关性增加。能源提供者和政策制定者要求天气信息以做出明智的选择并根据运营目标制定最佳计划。由于最近应用于卫星图像的深度学习技术的发展,使用遥感数据的天气预报也是重大进展的主题。本文使用基于U-NET的建筑研究了荷兰沿海海洋元素的多个步骤预测。在2年内跨越哥白尼观察计划的每小时数据已被用来训练模型并进行预测,包括季节性预测。我们提出了U-NET体系结构的一种变体,并使用残差连接,平行卷积和不对称卷积进一步扩展了这种新型模型,以引入三个其他体系结构。特别是,我们表明配备了平行和不对称卷积的体系结构,并且跳过连接优于其他三个讨论的模型。

The supply and demand of energy is influenced by meteorological conditions. The relevance of accurate weather forecasts increases as the demand for renewable energy sources increases. The energy providers and policy makers require weather information to make informed choices and establish optimal plans according to the operational objectives. Due to the recent development of deep learning techniques applied to satellite imagery, weather forecasting that uses remote sensing data has also been the subject of major progress. The present paper investigates multiple steps ahead frame prediction for coastal sea elements in the Netherlands using U-Net based architectures. Hourly data from the Copernicus observation programme spanned over a period of 2 years has been used to train the models and make the forecasting, including seasonal predictions. We propose a variation of the U-Net architecture and further extend this novel model using residual connections, parallel convolutions and asymmetric convolutions in order to introduce three additional architectures. In particular, we show that the architecture equipped with parallel and asymmetric convolutions as well as skip connections outperforms the other three discussed models.
