【摘要】：大氣強迫的日變化可以減弱海表溫度的水平梯度加強表層與次表層間的垂向混合,從而影響海溫的模擬。本文基于區(qū)域海洋模式ROMS,利用NCEP/NCAR發(fā)布的6h1次的10m風速、短波輻射、海表氣壓等再分析資料,研究了大氣強迫的日變化對東中國海溫度模擬的影響。通過與觀測資料比對發(fā)現,相比于日均大氣強迫下的模擬,日變化大氣強迫下的模擬與觀測更為接近。大氣強迫的日變化對東中國海的海-氣熱通量具有顯著影響,能夠使東中國海年均海氣熱通量增加1.4W/m~2,夏季增加13W/m~2,冬季減小10W/m~2。大氣強迫的日變化通過海-氣界面的熱力和動力過程影響水溫的垂直結構,加強東中國海的上層混合,使東中國�；旌蠈雍穸�(MLD)增加約10%;夏季黃海冷水團的平均溫度升高0.5℃,體積減少約1/3。
[Abstract]:The diurnal variation of atmospheric forcing can weaken the horizontal gradient of sea surface temperature and strengthen the vertical mixing between surface and subsurface, thus affecting the simulation of sea surface temperature. Based on the regional ocean model (ROMS), the influence of diurnal variation of atmospheric forcing on the temperature simulation of the East China Sea is studied by using the reanalysis data of 10 m wind speed, shortwave radiation and sea surface pressure released by NCEP/NCAR. Compared with the observational data, it is found that the simulation of diurnal atmospheric forcing is closer to that of daily atmospheric forcing. The diurnal variation of atmospheric forcing has a significant effect on the sea-air heat flux in the East China Sea, which can increase the average annual air-sea heat flux by 1.4 W / m ~ (2) in the East China Sea, 13 W / m ~ (2) in summer and 10 W / m ~ (2) in winter. The diurnal variation of atmospheric forcing affects the vertical structure of water temperature through the thermal and dynamic processes of the air-sea interface, strengthens the upper layer mixing in the East China Sea, increases the thickness of the mixing layer in the East China Sea by about 10%, and increases the average temperature of the Huang Hai cold water mass by 0.5 鈩，
