The invention discloses a sea wave significant wave height correction method and device based on a sea air temperature difference, computer equipment and a storage medium. The method comprises the following steps: calculating a Richardson number representing atmospheric stratification instability according to an air temperature Ta, an air temperature measurement height zt, a sea surface temperature Tw, a wind speed u and a wind speed measurement height z which are acquired in advance, and recording the Richardson number as Rb; according to the Richardson number Rb and a pre-obtained seawater depth D, calculating a correction coefficient, and recording the correction coefficient as xi; the corrected significant wave height is calculated according to the correction coefficient xi and the pre-obtained initial significant wave height Hsmod and recorded as Hscore, and the corrected significant wave height data is obtained, so that the phenomenon that the significant wave height is obviously small is overcome; and the physical process lacked in the current sea wave mode, namely the influence of the atmospheric stratification instability on the wind wave growth relationship, is supplemented.
Description
technical field [0001] The present application relates to the technical field of marine forecasting, in particular to a method, device, computer equipment and storage medium for correcting significant wave height of ocean waves based on sea-air temperature difference. Background technique [0002] Waves are the most common and important natural phenomenon on the ocean surface, and they are also one of the most important factors affecting the safety of marine navigation, marine fisheries and other related marine activities. Therefore, accurate observation of ocean waves (that is, ocean wave observation) is of great significance to the life safety of personnel participating in marine activities and the development of ocean economy. At the same time, ocean waves will also have a non-negligible impact on the state of the atmosphere through the air-sea interaction, thereby affecting the weather and global climate. Therefore, accurate wave observation is extremely important for b...
