为啥德国的空气质量比周边国家差这么多啊？网友：肯定是法国人熏的！

Wind usually comes from the west in Europe, so its obviously the French cigarette smoke.
欧洲这地儿一般刮西风，所以肯定是法国人抽烟熏的。

（法国）可颂放阴屁啦！

There is also the Alps to the South, which probably funnels the dirty air into that part of Germany.
Some of the places with the worst air quality dont have super high pollution, but the terrain is shaped like a bowl, so pollution gets trapped.
Winds and topography play a massive role in air quality, but it's not something most people think about.
德国南边不是有阿尔卑斯山吗？脏空气容易被兜着吹到德国这边。有些地方空气差，其实不是污染多，而是地形像个碗，脏空气跑不掉。风向和地形对空气影响贼大，不过一般人想不到这层。

Spoken like someone from Bakersfield。
这话一听就像是（加州）贝克斯菲尔德人说的。
注：贝克斯菲尔德是美国加州空气质量最差的城市之一，地形上是被山脉包围的盆地，有“尘土飞扬、污染严重、文化落后”的刻板标签。

Considering the astonishing amount and level of ignorance of all the factual wrong explanations in the comments, this actually comes closest to reality.
瞅了眼评论区一堆离谱的胡说八道，这个回答还算靠谱。​

Please save us from the dark abyss of ignorance and enlighten us with your unrivaled wisdom, facts and logic, oh great one.
请将我们从无知的黑渊中拯救出来，用您无与伦比的智慧、事实与逻辑启迪我们吧，大佬！

Closing of nuclear, and powering up coal?
（原因是）关闭核电，反而增加燃煤发电？

70 upvotes for a question that seems logical but simply wrong.
Forest fires and a heat bulb trapping winds are the answer. Germany normaly has some of the best air quality in Europe if the wind does not come from the east. There are the dirtiest coal plants (Eastern germany, Poland, Czechia).
看着挺对其实扯淡，居然还有70人点赞。​
森林火灾和热穹顶困住气流才是真正原因。通常情况下，只要不刮东风，德国的空气质量在欧洲属于较好水平。毕竟东边儿一堆煤电毒瘤，德国东部、波兰、和捷克。（注：一般认为波兰煤电站为欧盟最大污染源，带了点西欧清洁，东欧落后的叙事）

Coal plants in Poland use pretty good filters. It's nothing compared to what it used to be. One of the biggest factors in cold season in Poland have been houses and idiots using thrash as a fuel.
波兰的煤电厂都装有相当不错的过滤器，污染程度相比以前好多了。冬天波兰空气污染主要还是因为居民住宅和一些傻乎乎的人用垃圾当燃料。

As well as the usual industrial and transport sources, there are numerous forest fires in eastern and central Germany currently. Some of which have been burning for a couple of days already.
除了常见的工业和交通污染源外，德国东边和中部还有好几处山火烧了好几天没灭呢。

A few years ago the wildfires southeast of Portland Oregon USA were apocalyptic. We saw ash so prent for a second I mistook it for snow. (I noticed I could see my breath and for half a second I thought of Christmas. But then I remembered I was doing yard work in shorts. This was not snow.) A town about an hour south had a sky so red the landscape looked like a Martian movie scene.

I can definitely believe this is the result of wildfires.

几年前，美国俄勒冈州波特兰东南部的山火犹如末日景象。我们看到灰烬漫天飞舞，一瞬间我误以为那是雪。（当时我注意到自己能呼出白气，有那么半秒钟想到了圣诞节。但随即想起自己正穿着短裤在院子里干活，这绝不可能是雪）往南约一小时车程的小镇，天空红得像火星电影里的场景。​​
我完全相信德国的情况也是野火所致。

I remember bushfires in Australia causing apocalyptic red skies in New Zealand - 2000km away across a sea 
我记得澳大利亚那次森林火灾，把新西兰的天空都染成了末日般的红色，那地方离得远着呢，隔着大海有2000公里。

I was in the middle of all that. Everything was dark orange with haze straight out of a 90s 3D game. Months where it was hard to go outside.
在现场！那会儿所有东西都笼罩在暗橙色的雾霾里，活像90年代3D游戏的画面，连续几个月都出不了门。​​

I mean the latest Canadian wildfires had an effect on Europe a couple of weeks ago. It’s crazy. 
就前阵子的加拿大山火甚至影响到了欧洲，简直离谱。

Can you guys please stop your wildfires, it's getting hot over here in Europe. 
拜托你们的森林别再烧了，欧洲这里天气越来越热了。

Guess some forest raking is in order. 
看来是时候耙一耙森林落叶了。

Not wildfire related, but snowing ash: I remember when the Icelandic volcano Eyjafjallajökul exploded in 2010 and it snowed and rained ash for a while in intervals pending on the wind. It was a very odd, but also cool thing to expiernce, pretty far away from the source (Faroe Islands). visiticeland says: about 100.000 flights were canceled, but i mostly remember a disgusting snow-ash period and many people complaining about the ash making a spot on their cars paint.
虽然不是森林火灾，但说到火山灰像下雪一样，我记得2010年冰岛埃亚菲亚德拉火山喷发时，应该是因为风向变化吧，距离爆发地很远的法罗群岛间歇性地下了好一阵火山灰雪/雨，邪门儿又带感。网上说约10万架次航班被取消，但我印象最深的还是那场恶心的灰雪，以及很多人抱怨车漆被火山灰腐蚀出斑点。

The industrial and transport sources are irrelevant here. At the moment shown on the map, Germany was just at the peak of an extreme heat wave (the infamous heat dome weather condition) while a cold front had already reached France and the North Sea with rain and cooler and cleaner maritime air.
工业和交通污染背不上这个锅哦，地图显示的时间节点，德国正处于极端热浪（臭名昭著的“热穹顶”天气）的峰值，与此同时，冷锋已带着雨水和更凉爽清洁的海洋空气抵达法国及北海地区。​
注：“热穹顶”指高层大气热高压在一段时间内停滞不动，高压与附近低压之间的大气环流形成了稳定的“Ω”型，像个罩子一样。

This and Germany is also littered with air quality sensors... At least compared to some of the neighbouring countries。
而且德国空气质量监测点贼多，至少比某些邻国多得多。

I have family that live near a steelworks in the UK. You'd be surprised how often the official measuring points would have crucial locations down, no support for various pollutants or would average PM2.5 over a week to obfuscate massive spikes during some days. 
Germany are probably the only country measuring properly! 
我有亲戚住在英国一家钢铁厂附近，官方监测点动不动就坏，要么测不全污染种类，要么拿周平均数据糊弄人，德国大概是唯一真正认真监测空气质量的国家了！（德国还是老实啊）


Ricordis
Yeah, it is this. Years ago we started to measure how the air quality affects the people living in cities and near the traffic. We placed measuring stations everywhere and the results were horrific.
We got worse results because we are the only ones who measure it in that detail and by knowing we suck we don't have to cheat on those. Otherwise we would not be able to become better.
可不咋的。多年前我们开始测量空气质量对城市居民和交通沿线人群的影响。我们在各处设立监测站，结果触目惊心。​​
我们的数据更差，是因为我们是唯一进行如此细致测量的国家。正因为知道自己做得很差，我们才不必在数据上作假，否则我们将无法进步。
