An error estimation of the divergence of current
流场散度的误差估计

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.
