| 摘 要： | 用2006年夏～2007年秋在北部湾获得的船测气象资料,由块体公式计算了海-气通量.结果表明:北部湾春、夏季节获得热通量,而秋、冬季节失去热通量.春季通过湍流交换造成的热通量对海面热平衡的贡献最小,其次是夏季、冬季和秋季.在年平均尺度上感热通量和潜热通量分别占净辐射通量的7.4%和77.4%,15.2%的净辐射热量通过海洋过程消耗掉.感热通量随海-气温差的加大而增大,而与风速之间呈现复杂的非线性关系.海-气温差增加1 ℃,感热通量增加6.7～12.7 W/m2;较大的感热通量(>30 W/m2)容易出现在5～10 m/s风速条件下.潜热通量与风速和相对湿度呈明显的相关关系:风速增加1 m/s,潜热通量增加约18 W/m2,而相对湿度下降1%会导致6 W/m2潜热通量的增加. |

| Abstract: | Air-sea flux in Beibu Gulf was calculated by bulk formulae with vessel-measured meteorological data from Summer 2006 to Autumn 2007.The calculation showed that Beibu Gulf gained net heat flux in spring and summer,lost net heat flux in autumn and winter.The contribution of heat flux caused by turbulence exchange to the heat balance of sea surface was minimum in Spring,and maximum in Autumn. On the annual average scale,sensible heat flux was 7.4% of the net radiation flux,and latent heat flux was 77.4%.15.6% ... |
