Abstract

Possibility estimation of generating internal waves has been recognized as a difficult problem because of the complex generation mechanisms and insufficient in situ observation data of internal waves. In this study, a inference model based on the fuzzy logic technique was developed for estimating the generation possibility of internal waves. The marine environmental factors causing the occurrence of internal waves were distilled from ocean data and used as the inputs of the fuzzy inference model, and the generation possibilities of internal waves were used as the output of the model. The developed model was applied to the northwest Pacific, and the results were verified using satellite remote sensing images. The satisfactory results indicate that the inference model based on fuzzy logic is a useful first step in the development of generation estimation of internal waves and can be used as a supplement of traditional methods, which will be helpful for the risk assessment of ocean engineering.
