利用1998年11月~1999年2月中国第15次南极考察资料,讨论了普里兹湾附近陆缘水边界(CWB)两侧的水团分布,以及CWB的中心位置、锋面宽度、锋面强度、锋面的垂直深度和垂直厚度等物理特征的空间变化.并与1992年12月~1993年2月中国第9次南极考察资料进行了比较,说明了CWB的时间变化。同时,还进一步分析了CWB两侧海水运动的各向异性,以及动力高度场的形势。指出了动力高度槽、CWB锋面位置、流场切变线的一致性,合理地解释了绕极深层水涌升的动力学原因.
Based on the 15th Antarctic survey data of China from November 1998 to February 1999, the water mass distributions on both sides of the marginal water boundary (CWB) near Prydz Bay and the center position, front width, frontal intensity of CWB , Frontal vertical and vertical thickness and other physical features of the spatial changes. And compared with the 9th Antarctic expedition data of China from December 1992 to February 1993, showing the time variation of CWB. At the same time, the anisotropy of seawater movement on both sides of CWB and the situation of dynamic height field are further analyzed. Pointed out the consistency of the dynamic height slot, CWB frontal plane and flow field shear line, reasonably explained the dynamic reason of the water surge around the deep layer.
