正如前述,黑潮流系是北太平洋的西边界强流,它是北赤道流的延续部分,因此具有流速大,高温高盐等水文特性。 一、温盐值的基本指标 在东经130°以西,和北纬30°以南,黑潮流系的表层水温:夏季均在28°—30℃范围内,冬季则为20°—26℃左右,而盐度值为34.0—35.0‰范围内,并且冬季(34.5—34.8‰)大于夏季(33.6—34.5‰),夏季受降水及江河迳流的影响,盐度值可以降到34‰以下,但到50米层,盐度值均高于34‰。
As mentioned above, the Kuroshio Current is a strong current in the western boundary of the North Pacific Ocean. It is a continuation of the northern equatorial current and therefore has hydrological characteristics such as large velocity, high temperature and high salt. First, the basic indicators of temperature and salinity in the longitude 130 ° west, and latitude 30 ° south, the Kuroshio current surface water temperature: summer are in the range of 28 ° -30 ° C in winter is about 20 ° -26 ° C, and The salinity value is in the range of 34.0-35.0 ‰, and is greater in winter (34.5-34.8 ‰) than in summer (33.6-34.5 ‰). In summer, due to precipitation and river runoff, the salinity value can be reduced below 34 ‰, 50 meters layer, salinity values were higher than 34 ‰.
