【摘要】：利用MASNUM海浪模式、ECMWF高分辨率風(fēng)場對2012年8月份臺風(fēng)過程下的浙江海域的海浪狀況進行了數(shù)值模擬,與近岸觀測站的風(fēng)、浪資料進行了對比檢驗和誤差分析,最后針對8月份"達維""�？�"及"布拉萬"3個臺風(fēng)過程對浙江海域的影響進行了對比分析.風(fēng)速驗證結(jié)果顯示2個站點ECMWF風(fēng)速和觀測風(fēng)速的偏差分別為0.18、-0.34 m/s,平均絕對誤差則為2.57、1.96m/s,均方根誤差為3.40、2.65 m/s,與觀測風(fēng)速有較好的一致性.海浪驗證結(jié)果顯示8月份有效波高的相關(guān)系數(shù)在0.84以上;8月份發(fā)生的"達維""海葵"及"布拉萬"3個臺風(fēng)期間的有效波高、波周期的模擬值與觀測值的均方根誤差分別介于0.19~0.37 m、0.88~1.28 s,波向的平均絕對誤差介于19.39°~37.65°,表明MASNUM海浪模式能夠較好的再現(xiàn)浙江海域臺風(fēng)期間的海浪狀況,能夠較好模擬出浙江近海的最大波高.在數(shù)值模擬和實際觀測的基礎(chǔ)上,進一步的對比分析表明:"�？�"臺風(fēng)期間,浙江外海有效波高的最大值達7.6 m,而"達維"和"布拉萬"臺風(fēng)期間,數(shù)值顯示最大有效波高分別為4.4、5.4 m.
[Abstract]:The high resolution wind field of MASNUM wave model (ECMWF) is used to simulate the sea wave condition in Zhejiang during typhoon on August 2012, which is compared with the wind at the offshore observation station. The wave data are compared and tested and the error is analyzed. Finally, on August, "Davi", "sea anemone" and "Brawan" The results of wind speed verification show that the deviation between ECMWF wind speed and observed wind speed is 0.18. The mean absolute error was 2.57 / 1.96 m / s, and the root mean square error was 3.40 / 2.65 m / s. The results of wave verification show that the correlation coefficient of effective wave height in August is above 0. 84; In August, the effective wave height during the three typhoons of "Dawei" "sea anemone" and "Brawan", the root mean square error of the simulated wave period and the observed value was between 0.19 and 0.37 m, respectively. The mean absolute error of the wave direction is 19.39 擄~ 37.65 擄, which indicates that the MASNUM wave model can well reproduce the wave condition during the typhoon in Zhejiang. On the basis of numerical simulation and practical observation, further comparative analysis shows that: sea anemone during typhoon. The maximum effective wave height off the coast of Zhejiang is 7.6 m, while the maximum effective wave height is 4.44.4mduring the typhoon "Davi" and "Brawan".
