為啥德國的空氣質(zhì)量比周邊國家差這么多?。烤W(wǎng)友：肯定是法國人熏的！

Wind usually comes from the west in Europe, so its obviously the French cigarette smoke.
歐洲這地兒一般刮西風(fēng)，所以肯定是法國人抽煙熏的。

（法國）可頌放陰屁啦！

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.
德國南邊不是有阿爾卑斯山嗎？臟空氣容易被兜著吹到德國這邊。有些地方空氣差，其實(shí)不是污染多，而是地形像個(gè)碗，臟空氣跑不掉。風(fēng)向和地形對空氣影響賊大，不過一般人想不到這層。

Spoken like someone from Bakersfield。
這話一聽就像是（加州）貝克斯菲爾德人說的。
注：貝克斯菲爾德是美國加州空氣質(zhì)量最差的城市之一，地形上是被山脈包圍的盆地，有“塵土飛揚(yáng)、污染嚴(yán)重、文化落后”的刻板標(biāo)簽。

Considering the astonishing amount and level of ignorance of all the factual wrong explanations in the comments, this actually comes closest to reality.
瞅了眼評論區(qū)一堆離譜的胡說八道，這個(gè)回答還算靠譜。?

Please save us from the dark abyss of ignorance and enlighten us with your unrivaled wisdom, facts and logic, oh great one.
請將我們從無知的黑淵中拯救出來，用您無與倫比的智慧、事實(shí)與邏輯啟迪我們吧，大佬！

Closing of nuclear, and powering up coal?
（原因是）關(guān)閉核電，反而增加燃煤發(fā)電？

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).
看著挺對其實(shí)扯淡，居然還有70人點(diǎn)贊。?
森林火災(zāi)和熱穹頂困住氣流才是真正原因。通常情況下，只要不刮東風(fēng)，德國的空氣質(zhì)量在歐洲屬于較好水平。畢竟東邊兒一堆煤電毒瘤，德國東部、波蘭、和捷克。（注：一般認(rèn)為波蘭煤電站為歐盟最大污染源，帶了點(diǎn)西歐清潔，東歐落后的敘事）

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.
波蘭的煤電廠都裝有相當(dāng)不錯(cuò)的過濾器，污染程度相比以前好多了。冬天波蘭空氣污染主要還是因?yàn)榫用褡≌鸵恍┥岛鹾醯娜擞美?dāng)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.
除了常見的工業(yè)和交通污染源外，德國東邊和中部還有好幾處山火燒了好幾天沒滅呢。

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.

幾年前，美國俄勒岡州波特蘭東南部的山火猶如末日景象。我們看到灰燼漫天飛舞，一瞬間我誤以為那是雪。（當(dāng)時(shí)我注意到自己能呼出白氣，有那么半秒鐘想到了圣誕節(jié)。但隨即想起自己正穿著短褲在院子里干活，這絕不可能是雪）往南約一小時(shí)車程的小鎮(zhèn)，天空紅得像火星電影里的場景。??
我完全相信德國的情況也是野火所致。

I remember bushfires in Australia causing apocalyptic red skies in New Zealand - 2000km away across a sea 
我記得澳大利亞那次森林火災(zāi)，把新西蘭的天空都染成了末日般的紅色，那地方離得遠(yuǎn)著呢，隔著大海有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.
在現(xiàn)場！那會兒所有東西都籠罩在暗橙色的霧霾里，活像90年代3D游戲的畫面，連續(xù)幾個(gè)月都出不了門。??

I mean the latest Canadian wildfires had an effect on Europe a couple of weeks ago. It’s crazy. 
就前陣子的加拿大山火甚至影響到了歐洲，簡直離譜。


ElskerLivet 
Can you guys please stop your wildfires, it's getting hot over here in Europe. 
拜托你們的森林別再燒了，歐洲這里天氣越來越熱了。

Remarkable-Bug-8069 
Guess some forest raking is in order. 
看來是時(shí)候耙一耙森林落葉了。

Not wildfire related, but snowing ash: I remember when the Icelandic volcano Eyjafjallaj?kul 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.
雖然不是森林火災(zāi)，但說到火山灰像下雪一樣，我記得2010年冰島埃亞菲亞德拉火山噴發(fā)時(shí)，應(yīng)該是因?yàn)轱L(fēng)向變化吧，距離爆發(fā)地很遠(yuǎn)的法羅群島間歇性地下了好一陣火山灰雪/雨，邪門兒又帶感。網(wǎng)上說約10萬架次航班被取消，但我印象最深的還是那場惡心的灰雪，以及很多人抱怨車漆被火山灰腐蝕出斑點(diǎn)。

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.
工業(yè)和交通污染背不上這個(gè)鍋哦，地圖顯示的時(shí)間節(jié)點(diǎn)，德國正處于極端熱浪（臭名昭著的“熱穹頂”天氣）的峰值，與此同時(shí)，冷鋒已帶著雨水和更涼爽清潔的海洋空氣抵達(dá)法國及北海地區(qū)。?
注：“熱穹頂”指高層大氣熱高壓在一段時(shí)間內(nèi)停滯不動，高壓與附近低壓之間的大氣環(huán)流形成了穩(wěn)定的“Ω”型，像個(gè)罩子一樣。

Arcefix
This and Germany is also littered with air quality sensors... At least compared to some of the neighbouring countries。
而且德國空氣質(zhì)量監(jiān)測點(diǎn)賊多，至少比某些鄰國多得多。

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! 
我有親戚住在英國一家鋼鐵廠附近，官方監(jiān)測點(diǎn)動不動就壞，要么測不全污染種類，要么拿周平均數(shù)據(jù)糊弄人，德國大概是唯一真正認(rèn)真監(jiān)測空氣質(zhì)量的國家了?。ǖ聡€是老實(shí)?。?br />

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。多年前我們開始測量空氣質(zhì)量對城市居民和交通沿線人群的影響。我們在各處設(shè)立監(jiān)測站，結(jié)果觸目驚心。??
我們的數(shù)據(jù)更差，是因?yàn)槲覀兪俏ㄒ贿M(jìn)行如此細(xì)致測量的國家。正因?yàn)橹雷约鹤龅煤懿睿覀儾挪槐卦跀?shù)據(jù)上作假，否則我們將無法進(jìn)步。
