Description

technical field [0001] The invention relates to the technical fields of buoy measurement and big data processing, and in particular to a method, system, electronic device and computer-readable storage medium for evaluating the error of buoy swell wave height observation data. Background technique [0002] Swell is a common ocean phenomenon, mainly refers to the long-period sea surface waves left over after the local wind speed weakens or the wind direction changes, or generated by the storm sea area and propagated over long distances. Accurate observation of swell wave height has important scientific research significance and engineering practice significance for the research of momentum exchange in the air-sea boundary layer and the early warning and monitoring of ocean swell. [0003] Wave buoy (hereinafter referred to as buoy) is one of the main methods for long-term fixed-point on-site observation of swell. Because of its high reliability and accurate measurement, it is ...
