| 摘要: |
| 本文分析了渤海、黄海、东海海面热量平衡诸分量及其总和的季节变化,结果表明,进入海面的太阳总辐射是海洋从海面得到热量的主要来源;海洋从海面失去热量的主要原因,在黑潮海域是海面蒸发潜热耗失引起的,在近海海域,春、夏季海面有效回辐射耗热超过蒸发耗热,秋冬季相反。海气之间的感热交换量较小,冬季较明显。结果还指出,在3—8月海洋计温期,海洋从海面得到热量,在9—翌年2月海洋降温期,海洋从海面失去热量。 |

| HEAT BALANCE AT THE BOHAI SEA, HUANGHAI SEA AND EAST CHINA SEA SURFACES——Ⅱ. CHARACTERISTICS OF THE SEASONAL VARIATION |

| Abstract: |
| Analyses of the seasonal variation of heat balance and its components at the Bohai Sea, Huanghai Sea and East China Sea surfaces shouw that the main heat gain of the ocean from the sea surface is the incoming radiation, especially in the Kuroshio region, the main heat loss from the sea surface is the latent heat flux in the Kuroshio region in the whole year and near coastal region in fall and winter, the back radiation in the coastal region in spring and summer, the smallest heat flux is the sensible heat exchange. The results also show that the net heat gain of the ocean from the sea surface occurs in seasons from March to August and the net heat loss occurs from September to next February. |
