Description

technical field [0001] The present application relates to technical fields such as oceanographic surveying and big data processing, and specifically relates to a numerical model sea surface wind speed correction method, device, electronic equipment and storage medium. Background technique [0002] Ocean surface wind (sea surface wind) is the most common and important natural phenomenon on the ocean surface, and it is also the basic driving force for generating and affecting other important ocean phenomena such as waves and currents. Sea surface wind and the resulting waves are one of the most important factors that affect the safety of marine navigation, marine engineering and other related marine activities. Therefore, accurate prediction of sea surface wind will be of great significance to the life safety of personnel participating in sea activities and the development of marine economy. At the same time, because the friction of the sea surface on the sea surface wind is ...
