Abstract

The invention discloses an unstructured grid significant wave height prediction system based on deep learning, which comprises a long short-term memory (LSTM) model, and the unstructured grid significant wave height prediction system comprises a time sequence processing model composed of two LSTMs and is a recurrent neural network with an input gate, a forget gate and an output gate. The input of the model is the effective wave height data of the unstructured grid in 10000 hours provided by the FVCOM mode, and the final output is the predicted wave height in the future 1 hour, 6 hours, 12 hours and 24 hours.

Description

technical field [0001] The present invention relates to the technical field of time-space sequence prediction, in particular to a deep learning-based unstructured grid significant wave height prediction method and system. Background technique [0002] Ocean waves are an important research field in physical oceanography, and wave heights are affected by environmental changes and Earth systems, especially waves due to climate change. Sea state characteristics such as wave period, wave direction, and significant wave height are important safety factors that must be considered in activities such as ocean engineering construction, marine transportation, environmental protection, and military operations. Among them, the significant wave height of ocean waves is the most important, and accurate and reliable prediction of significant wave height is an important task in marine and engineering applications. Therefore, it is of great significance to carry out accurate operational fore...
