的实验有很多,通常面向孩子,涉及到瓶中“云”或类似的东西。这些练习对他们来说都是整洁的,但苍白的美丽相比真正的云。真的你只是雾在瓶子里。

Using currently available (preferably consumer grade) technology, is it possible to create real clouds? Or even better, a real weather system? Imagine you have an enclosed 10 ft wide cube. If you build a landscape inside, complete with mountains and bodies of water, and you have complete control over the boundary conditions of the cube (temperature, airflow in/out, etc.), can you reproduce the beauty of a towering cumulus cloud inside the cube? One step further... can you create thunderstorms?

I have a very rudimentary understanding of how weather works, but the engineer in me says in theory this should be possible. But in reality a lot of small details glare out at me as possible show stoppers. Aerodynamics does not scale, because of the constant size of air molecules at all scales. I suspect this limitation may affect my weather system puzzle as well. Also with respect to thunderstorms, I suspect the 10 ft wide cube may not be able to mimic the role of planetary grounding, atmosphere, etc., in the creation of electric discharges.

真正的云是美丽的,因为他们是巨大的,你观察他们,从而获得能够看到一个截然不同的“边界”,因此,形状。但是如果你曾经穿过云在一个平面上,从而看到一关闭,你会发现他们真的是“雾”。你会努力重建规模云在一个小环境;水分子有一个相当一致的大小和你不能只是整个系统缩减规模。

Similarly, you could probably create a thunderstorm but at that scale it would be over so fast you'd barely see it. An obvious example is the movement of water droplets as steam leaves your kettle and condenses. You just see a quick whoosh of vapour particles spiralling about and, well, that's about as close to a rainstorm as you'll get.

Some phenomena, such as air vortices, can manifest at smaller scales — I've seen more than a few mini-tornados forming in my garden dragging leaves around in a funnel fashion — but I'm not sure you'd ever be able to contain enough energy to see that happen for more than a fraction of a second in a small tube.

我记得读几次有一个非常大的NASA机库现象”下雨室内展出。“这不是屋顶的漏水,因为它可能是一个万里无云的夜晚,它仍然会发生。据说,有云形成内部的建筑。

你只需要一个足够大的空间,。你需要寒冷空气的顶部,底部,然后温暖的空气和水蒸气凝结。然后你可能会下雨,即使雪形成取决于温度。的条件是正确的云。现在如果你想创建一个雷雨,你需要空气运动,向上,向下,侧面等等。你定需要产生冰雹和强降雨。理论上的可能,但是它非常昂贵(你需要一个大规模的建筑/机库或圆顶,美国航空航天局;))和非常昂贵的设备,让它工作,另一方面,一旦你拥有它,您已经创建了一些没有人有史以来建造的最大的),你可以控制天气在封闭的环境中。

是的可以构建一个结构类似于你描述的,而这正是一些研究者使用研究云的形成和运作的过程。重新创建的其他答案和评论已经建立了全面的天气系统可能是不可能的,但< a href = " http://glossary.ametsoc.org/wiki/Meteorological_cloud_chamber " rel = " noreferrer " > <强>气象云室< /强> < / >存在再现特定的天气现象。你问关于”最好是消费者品位”的例子,但由于这些类型的设备都是有效的自定义构建在某种程度上,您可能会创建一个“消费级”版本(只是不一定期望从你的努力研究级数据!)。 从研究的角度来看,它们主要用于研究在云微物理过程:凝结的冰核,化学分子之间的相互作用在云、雪形成,水晶淞化,雷暴电气化等等。正如你所指出的问题,缩小问题意味着他们不适合大规模繁殖天气特征,虽然限制大如你建立它我想… 这是一个链接到一个< a href = " http://data.cas.manchester.ac.uk/micc/micc。htm noreferrer“rel = >研究级冰云室< / >,曼彻斯特大学的使用,英国。有一些优秀的照片是如何组合在一起(不幸的是我没有权限把它们)。本质上这是一个10米钢室,可冷却到-55摄氏度。压力可以降低模拟对流层上层的条件(约50 hpa)。在某些场合它被使用在雷雨电气化繁殖条件。 这是一个视频的< a href = " http://commons.wikimedia.org/wiki/File%3AHome_Made_Cloud_Chamber.webm " rel = " noreferrer " >自制云室在行动< / >(再一次,它是模仿在云,小规模的特性和过程不是天气系统本身。),和一个简单的如何设置图:< img src = " https://i.stack.imgur.com/SapZE.jpg " alt = "云室图" > 这里使用酒精,因为它比水更容易蒸发和冷凝。 The dry ice at the base cools the lower section of the chamber, creating a temperature gradient within the chamber. The alcohol droplets will evaporate from the strips forming a fog (cloud) at the top, then condense as they hit the cool air, forming gentle rain droplets nearer the base. Here's a link to more detailed instructions.

Something in between these kind of set-ups is the closest you will come to re-creating 'real' clouds at home. They won't have the beauty of a towering cumulus over a mountain range (although some say there is beauty in cloud microphysical processes.)

Annecdote 1: At the EGU 2014 Annual Conference in Vienna, the organisers created a series of rooms that you could walk through and experience being inside a cloud.

Annecdote 2: Incidentally the first person to create a 'weather chamber' was CTR Wilson, trying to reproduce the cloud formations he had seen on Ben Nevis in the Scottish Highlands. His invention actually led to the discovery of ionizing radiation. http://www-outreach.phy.cam.ac.uk/camphy/cloudchamber/cloudchamber_index.htm

我认为这将是必须气密我在我自己的理论,但小得多。我要尝试如何平坦地球的想法是上面有水的地方。所以我们的想法是我要把植物放在泥土活着的增长在一个玻璃球连同所需的气体。淹没在水里,如果没有发生这么长时间后我把虫子内部会发生如果没有其他更大一个n等等。

,麻省理工学院(MIT)提供了一个旋转槽设置。江南登录网址app下载这种所谓的“天气坦克”使大量的实验证明广泛的现象,发生在大气和海洋。添加不同的食物染料进入旋转罐可以可视化的现象,有时会产生漂亮的云雾状结构。我曾经有机会展示一些实验的孩子,和他们的反应非常好。 看到< a href = " http://weathertank.mit.edu/ " rel = " nofollow noreferrer " > < / >网站获得更多信息和指令。
