Problems solved by technology

[0004] To sum up, the existing forecasting methods mainly have single and isolated forecasting elements, and the tidal tide level and storm tide level are forecasted separately, and the interaction between the two is not considered, and the comprehensiveness of the forecast results is not high. High, the influencing factors considered in the forecast are not comprehensive enough, and the influence of ocean currents is not included, which cannot meet the needs of comprehensive water level prediction in coastal waters, and affects the efficiency and accuracy of comprehensive water level real-time forecasting, and there are certain limitations

Abstract

The invention provides a method and a system for forecasting comprehensive water levels of sea areas in real time, and belongs to the field of marine environment forecasting. The method includes reporting back the meteorology for the sea areas and constructing first meteorological force fields; reporting back water level sea current on the basis of the first meteorological force fields and acquiring water level sea current fields; forecasting the meteorology for the sea areas and constructing second meteorological force fields; forecasting residual water levels on the basis of the second meteorological force fields and constructing residual water level open boundary conditions; forecasting open boundary tide levels on the basis of the residual water level open boundary conditions and generating water level forecast values; forecasting the comprehensive water levels of the sea areas on the basis of the water level sea current fields, the second meteorological force fields and the water level forecast values. The method and the system have the advantages that the comprehensive water levels of the offshore sea areas can be forecast in real time, and the comprehensive water level real-time forecasting efficiency and precision can be improved.

Description

technical field [0001] The invention relates to the technical field of marine environment forecasting, in particular to a method and system for realizing real-time forecasting of comprehensive water levels in coastal sea areas. Background technique [0002] The water level changes in the coastal waters will directly affect the coastal areas, especially under extreme weather conditions such as typhoons and extratropical cyclones, the high water levels will cause serious disasters in coastal areas. The comprehensive water level includes not only the normal change of ocean water level dominated by tidal action under normal weather conditions, but also the change of storm surge water level under extreme weather conditions. According to the requirements of the national and local people's governments at all levels for marine forecasting work, realizing real-time prediction and early warning of comprehensive water levels in coastal waters will effectively improve the disaster preve...
