西北太平洋137°E断面海流的纬向体积输送
顾玉荷
中国科学院海洋研究所 青岛266071
摘要:
利用日本气象厅1967-1989年间沿137°E断面观测到的水文和海流资料,计算了该断面上1°S-34°N的纬向体积输送。纬向体积输送的明显特点是复强冬弱,无论是多年平均的还是个别年份的,不管是东向输送分量还是西向输送分量,该特征都是非常明显的。净输送量有非常大的年际变化,70年代以向西输送为主,80年代则以向东输送为主,峰值出现在ElNio事件前后,二者有一定的关系。

ZONAL VOLUME TRANSPORTS AT 137° E IN THE NORTHWESTERN PACIFIC

Abstract:
Two data sets from JODC obtained by the R/V Ryfou were used to calculate the volume transport along 137 ° E between 1° S - 34 ° N. Routine 1967 - 1989 meridional hydrographic data, from 23 repeated cruises in winter and 18 cruises in summer were used to calculate the geostropic volume transport between 3 -34° N (referred to 104 kPa). 1971 - 1985 subsurface current data (measured with two current meters, between 1° S - 8° N, 0 - 500m, obtained in 14 repeated summer and winter cruises) were used to calculate the transport between 1° S - 8° N. The eastward and westward components of the transport were calculated separately.

The basic features of the volume transport in this section were as follows. In the whole section the long term annual mean eastward and westward component of the transport in summer were larger than that in winter, but the net volume was not. Over most of the observed year the eastward and westward component of the volume transport in summer were obviously larger than in winter. The net transport showed very large interannual variation and in general was mainly westward in the 1970's, but eastward in the 1980 's, a few eastward peaks of the net transport appeared before and during the past El Nino events. There are some close relationship between the net volume transport and the El Nino events.

Key words:  137° E, Zonal volume transport, Interannual variation, El Nino
