纬向流动是指方向对称的带状剪切流动，是自然界和实验室中普遍存在的现象。现在人们普遍认识到，在几乎所有漂移波湍流的情况和情况中，纬向流都是一个关键的组成部分，以至于这个经典问题现在经常被称为“漂移波-纬向流湍流”。本文从理论、计算以及与实验结果的对比等方面提出了新的观点和统一的概念，有助于理解纬向流物理。特别强调确定取得进一步进展的途径。(c) 2006年美国物理研究所。
Zonal flows, which means azimuthally symmetric band-like shear flows, are ubiquitous phenomena in nature and the laboratory. It is now widely recognized that zonal flows are a key constituent in virtually all cases and regimes of drift wave turbulence, indeed, so much so that this classic problem is now frequently referred to as "drift wave-zonal flow turbulence." In this review, new viewpoints and unifying concepts are presented, which facilitate understanding of zonal flow physics, via theory, computation and their confrontation with the results of laboratory experiment. Special emphasis is placed on identifying avenues for further progress. (c) 2006 American Institute of Physics.
