中文摘要: |
本文利用波谱分析方法,研究了隆冬北半球极地涡旋的崩溃过程,指出极地涡旋的崩溃是中、高纬度环流相互作用的产物。当中纬度地区有长波脊向北发展时,有利于极地涡旋崩溃。当高纬度地区有西风角动量向南输送时,有利于极地高压的建立。 |
英文摘要: |
In this paper, by the method of power-spectra analysis, the collapse processes of the mid-winter polar vortex in the Northern Hemisphexe are investigated. It is shown that they are the consequence of interactions between atmosphere circuladons of higher and middle latitudes. The northward development of long-wave ridges of middle latitudes favors the collapsing and southward transport of positive angular momentum from higher latitudes favors the setting-up of the polar high. |
