简介:自从2003,这篇论文考察中央规模天气动力学的主要理论进步,包括:(1)平衡并且失衡的流动的动态机制被使用学习中央规模循环的开始和发展问题。对称的不稳定性和横向波浪的不稳定性在线和旋涡空气传送对流被分析,并且进一步的研究在非线性的对流对称的不稳定性上被做了。在强迫对流和不稳定的传送对流和中央规模运动的波浪特征之间的相互作用也被讨论。(2)动态边界层建模的中间的空气被开发。复杂非线性的相互作用在大气的边界层和自由大气层之间理论上被分析。低级前面的地形学边界层和另外的边界层的结构动态问题被讨论。(3)在东亚空气发行量的背景下面的meso-β-scale暴风雨的形成和发展与MPV(潮湿的潜在的涡度)的变化被诊断异例。,并且在潮湿的空气。
