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 system for realizing real-time forecasting of comprehensive water level in sea areas, belonging to the field of marine environment forecasting, to realize forecasting of comprehensive water level in coastal sea areas, and to improve the efficiency and accuracy of real-time forecasting of comprehensive water level. The method includes: performing meteorological reports on the sea area, constructing a first meteorological forcing field; performing water level and ocean current reports based on the first meteorological forcing field, and obtaining a water level and ocean current field; performing weather forecast on the sea area, constructing a second meteorological forcing field; The meteorological forcing field is used to forecast the remaining water level, and the open boundary condition of the remaining water level is constructed; the tide level is forecasted based on the open boundary condition of the remaining water level, and the water level forecast value is generated; based on the water level ocean current field, the second meteorological forcing field, and the water level forecast value, the sea area is analyzed. Comprehensive water level forecast.

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...
