OK , but thats how i understood it - any other reason ? because they figures are unnaturally low
They are not really. The most polluted areas in China have relatively high sunshine hours (areas around Beijing). The area around Sichuan, Guizhou and Guangxi province have always been known to be very cloudy and foggy for centuries and millennia.
The much sunnier Yunnan province to its south literally means "south of the clouds".
cloudy and foggy - certainly - but those figures are ridiculous and suggest a further added factor .
By that logic, is it likely that sunshine hours are over 3000 hours in Beijing? Its already at 2700 hours and one of the most polluted cities while the cloudy Sichuan basin and Guizhou province is at 1000-1300 hours.

1,000 hours of sunshine - that is just too low - nowhere in the world gets totals that low for a mainland location . Doesn't make sense to me .
1,000 hours are totals you'd find in sub arctic islands
No Windsor would be more like Detroit. Windsor being Canadian used the C-S method and averaged 2261 hours. Higher than places like Toulouse or Genoa or Milan or Venice. The poster makes it sound as if Detroit were nothing but cloud. You cannot go by Pt. Cloudy, Cloudy, Mostly Cloudy number of days etc. That is a highly inaccurate way to measure sunshine hours in the East cause we rarely get those days in summer. Most summer days are pt cloudy. I can't tell you how often the airport reading says mostly cloudy here, in any season, and the sun is shining bright and there are clouds about in the sky but far from cloudy.
Anyway, Detroit using the same numbers as Windsor is certainly not as gloomy as the Detroit poster believes compared to say northern Europe. What would he think living there considering Milan, Toulouse, Genoa, Bologna, Rimini, and Venice all get less sunshine hours annually than Windsor. Even a place like Plovdiv in Bulgaria is barely sunnier.
And keep in mind, Detroit is in one of the least sunny regions of the USA when you look at sunshine maps for this country. The Great Lakes are known for that due to winds blowing over the lakes and creating clouds and fog, etc. even in summer.
The diff between Detroit (US method) and Windsor (Europe method) is 172 hours. Now this is just anecdotal, but based on reading expat forums and talking to Americans (like my own brother) who have lived in Europe, they feel it is definitely cloudier than here and easily noticeable.
I think most Americans when living in Europe are surprised at how cloudy much of Europe really is compared to here, different sunshine methods notwithstanding.
I would say that in Europe the sunshine differences are pretty strong in relatively short distances between north and south. I mean, look at Paris and Marseille.
As for me, when I lived in Toronto I did not think of it as a cloudy climate. At least it seemed sunny dry cold days were common in the winter. I don't think i live in a cloudy climate now either, but the problem is mostly the winters. Still, looking at this map it seems like many places in the eastern part of the US have relatively similar sunshine as here, but of course it is not very detailed. It would be nice to have something more precise.
