Norilsk 596/(-9.6+10) = 1490. Beat that!
Milwaukee 883/(8.8+10) = 47.0, humid. I agree that I live in a humid climate. Subhumid starts at 752mm and semi arid at 564mm. Years below 752 aren't unusual, but below 564 is rare. 2003 was the last year that was close (566mm), before that 1963.

Western Europe
London = 28.2
Paris = 28.6
Amsterdam = 41.5
Brussels = 41.6
Dublin = 38.3

London and Paris semi-arid, while Brussels humid? Ok, that's proof that this index a load of rubbish.

Brussels and Amsterdam are both a lot wetter and noticeably cooler year round than London or Paris. I am more surprised than Dublin has a lower figure than Amsterdam, more than the difference between Brussels and London. |

For Milwaukee, the normal formula is 883/18.8 = 47.0. Adjusting the cold months gives 883/(19.7) = 44.8. For Moscow, the normal formula gives 707/15.8 = 44.7. Adjusting the cold months gives 707/17.5 = 40.4.
For Yakutsk, the normal formula gives 237/1.2 = 197.5. Adjusting the cold months gives 237/15.4 = 15.4.
Then again, a month with a mean below freezing will have very little evaporation. Yakutsk is not an arid climate. I don't think months below 0 should be replaced with 0.

A lot wetter and noticeably cooler my ass. The difference is minuscule.
Bergen is a lot wetter and noticeably cooler than Paris.

Brussels annual mean is 1c cooler than Heathrow and 2c cooler than Montsouris. London has 600mm, while Brussels has 850mm. The wettest year in the last 30 years in London was 2014, which recorded 840mm and had an index of 38.2. |

Helsinki Centre, annual precipitation 655 mm, de Martonne 41.2
Oslo, 803 mm, 47.8 Belfast, 939 mm, 47.7 Chicago, 993 mm, 47.7 Copenhagen, 646 mm, 33.8
Hanover, 661 mm, 33.7
Vienna 651 mm, 31.9
Seems it works pretty poorly with locations with winter mean temps below freezing.
Brussels annual mean is 1c cooler than Heathrow and 2c cooler than Montsouris. London has 600mm, while Brussels has 850mm. The wettest year in the last 30 years in London was 2014, which recorded 840mm and had an index of 38.2.
Indeed, a minuscule difference in mean temps and rainfall. Thanks for proving my point.

The UK has a lot of people living on an island with small climatic differences, so maybe that's why a small difference like 1C different mean annual seems substantial?
When I drive 2 hrs to Røros, I have moved to a climate with mean annual temp 5C colder than here. What's the difference in mean annual temp between London and Glasgow, 2C?

The sole reason is that the de Martonne index is making London look more arid than it actually is, and B87 absolutely loves shit like that.

For Trondheim AP: 54 - humid
A few others in Norway:
Namsos, 200 km further north of here: 88 humid Oppdal, 100 km south of here: 37 subhumid
Lærdal (innermost Sognefjord): 29 semiarid Brekke (outer Sognefjord): 210 I would call that hyperhumid
Alta: 34 subhumid
Edit: corrected Lærdal to semiarid

London's annual mean is 2c warmer than Glasgow, but it also has less than half of the precipitation. So Brussels, with a Martonne aridity index value 47% higher than London, has a preciptation total 42% higher than London. Strange that! You are just annoyed that London isn't the drizzly, foggy and damp hellhole that you wished it was. |

IDGAF about London. All I'm saying is that if London and Brussels get so dramatically different indexes though being climatologically very close, the system cannot be anything but flawed.

But the Brussels index is 40% higher, because it has 40% more rainfall. Brussels rainfall total is closer to Seattle than it is to London or Paris. |

Again, just another proof of a deeply flawed index.

This index is a cool idea. For my current climate, (1151mm / 22.4C) comes out to 51.4, so humid, which makes sense as it’s decently rainy year-round here. For my dream climate, (1001mm / 27.1C) comes out to 36.9, into the subhumid category and not semiarid, thus showcasing that it’s a true Mediterranean climate.

St. Cloud: 720 mm / 15.9 C = 45.3; humid.
I agree this climate is humid, but not extremely so. It's a cool/cold climate for the most part, so 720 mm yields a lot of lushness, but it's not an extremely wet climate either. Quite dry in winter but winter has little evapotranspiration anyways.

Please don't throw us all on this same boat. Eh, it’s probably true though. London to Edinburgh really isn’t a huge climatic difference but it certainly feels that way to most people in the UK. It’s not just B87 - I’ve heard plenty of people down south in real life talk about the climate up north like it’s Reykjavik or something. It’s understandable mind you. When you grow up in a relatively small country with negligible climatic differences, you’re bound to exaggerate those differences. In Leeds people talk about Manchester like it’s the wettest city on earth. |

It’s not just B87 - I’ve heard plenty of people down south in real life talk about the climate up north like it’s Reykjavik or something. I sense there's an element of people expecting it to be a certain way and adapting their perceived experience towards that. Edinburgh really isn't all that much colder in winter than most other sizable UK cities, but people pretend that it is. I know a man from Middlesbrough who swears that it's much warmer here than it is up there. Looking at the stats, I see no reason why he should feel that way. |
