Can somebody do Sydney's?

I'm horrible at math.

Equation 1

A=64
B=18.2
C=11 (35.8&46.6 avg to 41.2, so approx zone 11)
D=72.2
E=54
F=?
G=?
H=?

64-18.2+(2*11)+(72.2-72)+(54-32)+([72.2-50]/3)=F
45.8+22+0.2+22+(22.2/3)=F
67.8+22.2+29.4=F
F=119.4

(64/32)*(64-32)=G
2*32=G
G=64

F+G=H
119.4+64=183.4 so Sydney is B group and gets letter 'c' for summer month (64-73.9)

Equation 2

n1=64*2=128
n2=25
y=47.74*10=477.4
(n1+n2)/y=x
(128+25)/477.4=x
153/477.4=0.32 so humid climate with no dry season

And since it is humid no dry season B group with non a or b for summer month, rainfall/humidity letter is 'o'

In conclusion, Sydney, Australia is Boc / Warm Oceanic Warm Summer

I think category E needs to be tweaked. Many continental, even hot summer continental, climates are falling in the subpolar (Ed) category. For instance Harbin, which falls in the Ed category, should be in the D (continental) category. Maybe a climate that falls below 0 on the first equation but has a yearly mean of 32 F / 0 C or higher would be continental. So it would be:

If H is 0-59.9 or below 0 but yearly mean is 32 F or higher=D Group (Continental)
If H is below 0 AND warmest month mean is below 32 F=E Group (Subpolar/Tundra/Ice Cap)

Harbin, for instance, averages 40 F in its yearly mean. Not subpolar.

I wouldn't put a climate in a "polar" grouping if it had a yearly mean above freezing, unless said climate was a tundra (roughly speaking) such as Kerguelen, Macquarie Island, parts of southern Tierra del Fuego, parts of far northern Scandinavia, etc.

Other than that it's a good classification system.

Macquarie Island, for instance, has a result of about 41 in the first equation, putting it in category D, but since its hottest month averages 45 F only, it would be tundra. I guess it would be in category Ee?

To be in the A through D groups, you have to have at least one month 50+, so Macquarie Island due to a warmest month of 44.7, is automatically Ee despite Equation 1 coming out to approximately 40

There are Koppen subpolar climates with annual means as high as 5°C, if you read the wikipedia article on subpolar, it says typical annual means for the climate group are +5°C to -5°C (41 to 23°F)

Fort McMurray,AB,Canada has an annual mean of 33.8 and they are subpolar for both Koppen and my system

I have a change that I think you can support, If equation 1 is less than zero and the warmest month is 50+, to be subpolar, H+D (H+warmest month in °F) has to be 0 or less. If it is 0.1 or higher, then climate is D group

Works for me!
