In section one, by using FICE scheme and TIME-GCM, a model of trace gases and OH airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and OH airglow are analyzed. The result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another. In this process, gravity wave undergoes growth, overturning, convection and breaking. And the no-isothermal structure can accelerate the breaking of gravity wave in mesospause, and the breaking of gravity wave is an important source of convection and small-scale waves. The propagation of gravity wave will affect the distribution of minor species.

在第一部分的工作中，利用全隐欧拉格式和全球热层-电离层-中间层-电动力学环流耦合模式，对重力波的非线性传播及其在传播过程中对中高层大气中氧族和氢族成分和与之密切相关的OH气辉辐射的影响进行了数值模拟，结果表明，从对流层向上传播的重力波经历了产生、发展、饱和、对流产生直至破碎的非线性演化，大气的非等温结构加速了重力波在中层顶区的破碎，重力波的非线性传播是小尺度对流和湍流产生的一个重要的源。

Gravity wave and ozone are two interesting topics in the middle and upper atmosphere. In this dissertation, they are studied by numerical simulation and instrument development respectively.In section one, by using FICE scheme and TIME-GCM, a model of trace gases and OH airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and OH airglow are analyzed.

Aluminium prices started the second week of July with a spurt above US$3,300/t on the back of production woes coming from the Shanxi region in China. Previous attempts to breach the US$3,100/t barrier in June and May were short lived with prices not finding the support needed to stay above those levels. Aluminium bounced back with renewed strength in July on further power driven supply fears and new long positions entering the market. In June momentum came from production disruptions in UK (at the 145,000 tpy Holyhead smelter) and India (at the 360,000 tpy Angul smelter) and news that two smelters in the US (Glencore's 168,000 tpy Columbia Falls and Alcoa's 267,000 tpy Rockdale smelters) were curtailing their production levels on the back of prohibitive power prices. LME 3M prices tested the US$3,200/t level at the end of the month but the bulls appeared to hesitate to bridge that mark retreating towards US$3,150/t at the beginning of July.

中国山西的生产危机推动铝价在7月份第二周周初站上3，300美元/吨。5月份和6月份铝价试图突破3，100美元/吨的关口，但这仅是昙花一现，铝价并没有找到站上这个价位的支撑。7月份铝价反弹，电力危机引发供应担忧以及新的多头进场推动铝价走强。6月份，英国（年产能145，000吨/年的Holyhead冶炼厂），印度（年产能360，000吨的Angul冶炼厂）以及美国两座冶炼厂（Glencore公司旗下年产能168，000吨的Columbia Falls冶炼厂和Alcoa公司旗下年产能267，000吨的Rockdale冶炼厂）因电价上涨宣布减产，从而为铝价走势提供了动能。6月末，LME三个月期铝价格上探3，200美元/吨这一价位，但市场做多动力不足，铝价在7月初回调至3，150美元/吨。
