| 摘要: |
| 本文利用1986年及1987年秋季在菲律宾以东海域进行的CTD观测资料,分析了该海域上层海水热含量分布及变化,得出,热含量由南向北随纬度逐渐增大,这主要是北赤道流引起的等温线自南向北下倾造成的,另外也与南部和北部的冷涡和暖涡有关。本文认为,两年里热含量的差异可能与1986年生成的El Nin有关。另外,北太平洋赤道流体积输送量的变化与菲律宾海热含量的变化也有一定的联系。 |

| A PRELIMINARY ANALYSIS OF THE HEAT CONTENT DISTRIBUTION AND CHANGE IN THE PHILIPPINE SEA |

| Abstract: |
| Based on the CTD data gathered in the fall of 1986 and 1987 in the philippine Sea with R/V Science 1, heat content in the upper layer is examined in terms of distribution and change. The result shows that the heat content increases with latitude northward. Obviously the northward increase of the heat content is associated with the northward declination of isotherms, which probably is caused by the North Equatorial Current. In addition, the cold eddy and the warm eddy in the south and the north, respectively made to certain extent contribution to the heat content. The difference in heat content between 1986 and 1987 seems to be related to El Nino formed in 1986. On the other hand, the heat content is also associated with the volume transport of the North Equatorial Current. |
