How would you subdivide köppen's climate zones? (warm, averages, temperatures)

[JohnnyIsAPoser]

Here's how I would subdivide some of them

For CFA, commonly criticized for being too large, I would subdivide it like this:

CFA.A (lower humid subtropical) - CFA climates where the coldest month's average low is 5°C or more (example: central Florida/

CFA.B (upper humid subtropical) - CFA climate zones where the coldest month's average low drops below 8° but still has 8 months of average mean temperatures above 10°C (example: rock hill, SC where I live)

CFA.C (hot-sumner oceanic) - CFA climate zones with less than 8 months of monthly averages mean temperatures above 10°C, what trewartha considers oceanic (example: Washington, DC)

I would also subdivide the tropical climates into "tropical" (places like Miami with slight temperature variation) and "equatorial" (places near the equator with little temperature variation) and with the s, w, m, and f for each

Anyway, what do you think? How would you subdivide köppen's classifications?

Since there's not much difference between 21/29C (Miami annual) & 24/31C (Singapore annual), except your tropical climates subdivision, the rest of them sound good. Those places with slight temperature variation are mostly the borderline between subtropics & tropics, that means they are almost cool enough to be subtropics.

Yes, Melbourne is clearly much warmer and sunnier than those cities (London, Amsterdam) in Europe which have real oceanic climate. So I think it's hot-summer oceanic by your subdivision.

And of course, Brisbane is much warmer than northeastern US (south of NYC, Philadelphia) and East Asia (Tokyo). It is more subtropical than those cities in NH. Thus this subdivision is also fine.

Anyway you would subdivide other climate zones?

Maybe subtropical highland climates having their own category? Cwb is kind of a subtropical highland category, but it feels weird for cities like Quito and Bogota being in the same zone as London and Paris.
