摘要:

飓风是一种围绕一个确定的中心循环的气旋,其封闭风速超过75英里/小时,起源于热带和亚热带水域。飓风登陆时会造成严重的灾害。准确预测其轨迹路径对于减少经济损失和拯救人类生命至关重要。考虑到天气数据的复杂性和非线性,循环神经网络(RNN)可能有助于对飓风行为进行建模。我们提出了一个完全连接的RNN的应用程序来预测飓风的轨迹。我们在细网格上使用RNN来减少典型的截断误差。我们利用国家飓风中心(NHC)公开提供的纬度,经度,风速和压力来预测每隔6小时的飓风轨迹。结果表明,该技术是有竞争力的,目前采用的方法由NHC和可以预测长达约120小时的飓风路径。

英文摘要:

Hurricanes are cyclones circulating about a defined center whose closed wind speeds exceed 75 mph originating over tropical and subtropical waters. At landfall, hurricanes can result in severe disasters. The accuracy of predicting their trajectory paths is critical to reduce economic loss and save human lives. Given the complexity and nonlinearity of weather data, a recurrent neural network (RNN) could be beneficial in modeling hurricane behavior. We propose the application of a fully connected RNN to predict the trajectory of hurricanes. We employed the RNN over a fine grid to reduce typical truncation errors. We utilized their latitude, longitude, wind speed, and pressure publicly provided by the National Hurricane Center (NHC) to predict the trajectory of a hurricane at 6-hour intervals. Results show that this proposed technique is competitive to methods currently employed by the NHC and can predict up to approximately 120 hours of hurricane path.
