Abstract Based on the data of seawater transparency and seawater turbidity,this paper gives a quantitative prediction model of "blue ocean" meteorological index,and analyzes its influencing factors,especially meteorological elements.The analysis shows that the prediction model of seawater transparency established by linear_model modular in scikit-learn machine learning library is effective.The "blue ocean" phenomenon is closely related to seawater transparency and "blue ocean" meteorological index can be quantified by the seawater transparency prediction model.Tidal range,sea state level and temperature have a significant impact on the "blue ocean" meteorological index.The index has a positive correlation with the temperature and a negative correlation with the wind.
