在 1993/1994 的夏天在西藏的高原和 NCEP/NCAR 分析数据,在东方西藏的高原降雨之间的关系和向西和平的副热带的高度的 southward/northward 移动上基于平淡的降雨数据被学习。结果显示出那:向西和平的副热带的高度反常地被定位到更南部的纬度,高山脉主要是在它的过程的伪双周刊 southward/northward 摆动向北方在 1993 从 5 月变到 8 月;但是它反常地被定位到更北的纬度,高山脉显然是在它的过程的 30-60-day southward/northward 摆动向北方在 1994 从 5 月变到 8 月。同时,东方西藏的高原降雨 active/break 的变化有高山脉 southward/northward 摆动的类似的特征,这被发现。因此,在夏天的向西和平的副热带的高度的 southward/northward 移动可能与东方西藏的高原降雨 active/break 的变化有关。[出版摘要]
Based on the routine rainfall data on the Tibetan Plateau and NCEP/NCAR reanalysis data, the relationship between the eastern Tibetan Plateau rainfall and the southward/northward shift of West Pacific subtropical high in summer of 1993/1994 is studied. The results show that: the West Pacific subtropical high is abnormally located to more southern latitude and the high ridge is mainly the quasi-biweekly southward/northward oscillation in its processes of northward shift from May to August in 1993; but it is abnormally located to more northern latitude and the high ridge is obviously 30-60-day southward/northward oscillation in its processes of northward shift from May to August in 1994. At the same time, it is found that the changes of the eastern Tibetan Plateau rainfall active/break have the similar characteristics of the high ridge southward/northward oscillation. Therefore, the southward/northward shift of the West Pacific subtropical high in summer may be related to the changes of eastern Tibetan Plateau rainfall active/break.
