The invention discloses a method for pre-estimating effective height of sea waves based on CMIP5. The method comprises following steps of acquiring original data from ERA-Interim and CMIP5 series of tests and carrying out data preprocessing; selecting a proper sea level pressure field; using data of 1981-2000 years in the ERA-Interim to correct a prediction mode; using data of corresponding periods in the CMIP5 to estimate an optimal prediction mode; using the prediction mode to pre-estimate effective heights of future sea waves. According to the invention, by using the data of CMIP5 and the long-term stable ERA-Interim re-analysis data of the European Centre for Medium-Range Weather Forecasts, extracting data of effective heights of the sea waves therefrom; and using the method of a multiple regression model, pre-estimating effective heights of the multi-time sea waves. According to the invention, based on the traditional atmosphere-ocean coupling mode, an earth system mode is firstlyintroduced; by use of the test data in the CMIP5, problems of periods and reliability of observation data are solved; sea wave protection work of costal zones can be effectively guided; and the method is high in operability.
Description
technical field [0001] The present invention relates to the field of ocean wave parameter calculation, in particular to a method for estimating the effective wave height of ocean waves based on CMIP5 (Phase 5 of Coupled Model Intercomparison Project, abbreviated as CMIP5). Background technique [0002] Ocean waves are the ocean phenomenon most directly and closely related to human beings, and have a non-negligible impact on people's production and life. For example, sea navigation, fishery production, offshore oil platforms, and wave energy utilization are all closely related to ocean waves. [0003] Significant wave height is an important parameter to reflect the characteristics of ocean waves, so the prediction research of wave height has important practical significance. To predict the wave height of ocean waves, long-term and stable ocean wave observation data must first be obtained. However, although traditional observation methods such as buoys can accurately obtain i...
