| 摘要: |
| 按照误差传递原理,推导出流场散度的误差估计式,并将其应用于赤道中东太平洋上升流区域水平散度误差的估计。应用结果表明:赤道中东太平洋上升流区多年平均流场的散度稳定,平均散度约为3.0×10-7s-1;和通常采用的误差估计公式相比,该估计公式降低了散度误差,从而提高了散度的可信度。 |

| An error estimation of the divergence of current |
|
|
| Abstract: |
| According to the error translation rule, an error estimation of the divergence of current is given, and is applied to calculating the horizontal divergence of current in the equatorial center-eastern Pacific. The results show that the horizontal divergence of annual mean current in the equatorial center-eastern Pacific is steady, and the mean divergence is about 3.0×10-7 s-1. The error estimation is smaller than the usual error estimation, and hence the reliability is increased. |
