Satellite remote sensing-based sea surface drift and oil spill drift and diffusion forecasting method

Abstract

The invention relates to a satellite remote sensing-based sea surface drift and oil spill drift and diffusion forecasting method. The method comprises the steps of S1, collecting data; S2, building three-dimensional temperature, salinity and current numerical forecasting models, and obtaining a sea surface current field; S3, establishing a drift dynamic forecasting mode of sea surface drifts, andobtaining drift path results of the drifts; S4, establishing an oil spill drift and diffusion dynamic forecasting mode, and obtaining drift paths and diffusion results of oil spillage; and S5, obtaining drift path results of drifts of different forecasting institutions, and in combination with the drift path results of the drifts obtained in the step 3, obtaining the optimal drift path result of the drifts; and meanwhile, obtaining the drift path results of the drifts of the different forecasting institutions, and in combination with the drift paths and the diffusion results of oil spill obtained in the step 4, obtaining the optimal drift path and diffusion result of oil spill. Compared with the prior art, the method overcomes the limitation of a forecasting institution; and multiple driftand diffusion forecasting results are integrated, so that the forecasting precision is improved.

Description

technical field [0001] The invention relates to the technical field of maritime search and rescue and the technical field of oil spill drift and diffusion prediction, in particular to a method for forecasting sea surface drift and oil spill drift and diffusion based on satellite remote sensing. Background technique [0002] With the expansion of the scale of ocean development and the rapid development of my country's offshore oil industry and offshore oil transportation industry, the scale of offshore oil exploration, development, and submarine pipeline laying continues to expand, frequent maritime activities, people falling into the water, ships, and various marine oil spills Sudden accidents at sea occur from time to time, and marine accidents are more concerned by people. Maritime accidents will bring huge disasters to the coastal countries of the world politically, economically and militarily. They will not only cause casualties and property losses, but also bring adverse...
