Abstract

The invention provides a forecast quality evaluation method and device for offshore sea surface wind. The method comprises the following steps: acquiring inspection and evaluation elements of sea surface wind forecast, forecast data to be detected and live observation data; if trend change exists in the forecast data, dividing the forecast time efficiency of the forecast data into a change time period and a non-change time period, and determining the change time period of the forecast time efficiency, forecast information of the change time period and forecast information of the non-change time period; performing quality evaluation on the forecast data of each time period according to the forecast information and the observation information of each time period; and if a cyclone appears in the forecast time, judging whether the quality evaluation is effective or not according to whether the actual cyclone center enters a forecast sea area or not and the distance between the actual cyclone center and the observation point or not. The method can solve the problem of quantitative evaluation of forecast quality of different trend changes in sea surface wind forecast, the problem of large evaluation result error when the weather changes drastically, and the problem of cyclone influence.

Description

technical field [0001] The invention relates to the technical field of marine forecast and inspection, not to numerical model forecast, in particular to a method and device for evaluating the forecast quality of offshore sea surface wind. Background technique [0002] In the past, marine forecasting organizations used manual qualitative assessment (using 4 or 8 East Asian weather maps and live ship observation data per day to subjectively evaluate the published forecasts) due to the lack of sea observation data. ), there is no scientific and unified evaluation method and standardized evaluation process, and the lack of objectivity, scientificity and fairness seriously restricts the objectification and standardization of forecast quality inspection and evaluation, which is not conducive to the development and improvement of forecast technology. [0003] In recent years, with the deployment of more and more ocean observation buoys, the ocean observation buoys have almost cover...
