This thread is a continuation of the discussion in the recent thread Climate cities in the same classification but very distinct in nature? , i.e. Climate cities in the same classification but very distinct in nature?. In the thread many posters objected to the broad classification of Koppen's Cfb climate. Below I will suggest some possible changes to this.


I propose an distinction between different kinds of oceanic climates as follows:

No. of months 13'C or above:

7 or above - Warm oceanic climate (Annual average must be below 17'C)
5-6 - Typical oceanic climate
3-4 - Cool oceanic climate
0-2 - Subpolar oceanic climate (Annual average must be 5'C or above)

If the climate has one or more months with a monthly average of 1'C or lower, it is considered a semi-continental oceanic climate. What do you think?

Can't agree with this. I don't see my climate as the same as Amsterdam or London.

I don't see my climate as fundamentally different to Hastings or New Plymouth.

I feel your climate has more in common with a Highland tropical climate than a typical oceanic climate...

Interesting -in what way?

Typicalness in oceanic climates is relative, I think - I see NZ climates as quintessential oceanic climates, and the likes of NW Europe as "Northern climates"

London - typical oceanic

Paris - typical oceanic

Bilbao - typical oceanic

Dublin - cool oceanic

Vancouver - cool oceanic

Auckland - warm oceanic

Hobart - typical oceanic

Using the definition of distinct in nature, I don't see Vancouver as being distinct from London, while I do see Hobart and my climate as distinct from those two - I'd say very distinct.

Your climate seems to have very high diurnal temperature ranges and sunny winters which are not really different from summers percentage wise. These are not traits most people would consider typical for an oceanic climates I think. Most oceanic climates have narrow diurnal ranges due to oceanic influence and winters tend to be gloomier than summers on a percentage basis even at equivalent areas to your latitude like Northern Spain it seems to be the case.

Vancouver is in the typical oceanic camp with Mediterranean influences according to the OPs criteria.

I'd call Bilbao a warm oceanic climate too, especially considering it's not much cooler than Auckland (much closer to Auckland than to Paris or London).

Those ratings are based on the classification in the 1st post.

My own system's oceanic types:

Temperate Oceanic (C3to): annual Tº 3ºC to 10ºC, winter mean <5ºC, summer mean <15ºC, Pp>=1000mm.

Cool Hyperoceanic (C3ch): annual Tº 3ºC to 12ºC, winter mean <5ºC, Pp>=1500mm.

Warm oceanic (W2wo): annual Tº 15ºC to 20ºC, summer mean <20ºC, Pp>=1000mm.
