海洋仪器的精心研制和有效地使用,是促进海洋科学技术发展的重要一环。选用精良仪器、充实新的技术对海洋科技资料的准确性也起着重要作用。所以这是海洋事业发展的迫切需要。海洋局为了更新海浪观测仪器、改进海浪观测和波高计算方法、提高资料准确度,在北海分局小麦岛海洋站对新型仪器H_(AB)-2型岸用光学测波仪和波高观测方法进行了对比试验。通过35次海浪观测资料表明,用H_(AB)-2型比H_(AB)-1型岸用光学测波仪观测海浪、波高准确度提高0.2米。在四种波高计算方法中,选择了平均位置法作为最佳海浪观测计算方法。
The careful development and effective use of marine instruments is an important part of promoting the development of marine science and technology. Selection of sophisticated equipment, enrich the new technology on the accuracy of marine science and technology information also plays an important role. So this is an urgent need for the development of the marine industry. In order to update the wave observation instruments, improve the wave observation and wave height calculation method and improve the data accuracy, the Oceanic Administration carried out the H_ (AB) -2 shore optical wave instrument and the wave height observation method at the Wheat Island Marine Station of Beihai Branch Comparative Test. The observations of 35 ocean waves show that the accuracy of wave height is improved by 0.2 m with H_ (AB) -2 type H_ (AB) -1 shore optical wave instrument. Among the four wave height calculation methods, the average position method was selected as the best wave observation calculation method.
