Auckland and even more climates climates like mine, see a pronounced summer minimum, but without much of an increase in sunshine. That is in stark contrast to all other Cfb climates, and is due to the high levels of convective cloud.

I'm not comparing it to southeastern US climates, or any other climates. Just pointing out that it's summers are more a case of moderated weather from warm fronts, rather than a continuation of the westerly flow.

Interesting distinction there.

You were comparing to northwestern Europe just earlier.

Huh? I'm not sure what that means. Is the prevailing weather no longer from the west in the summer? The warm fronts don't come from the west? What exactly is "weather from warm fronts"? A warm front brings a change from a cooler air mass to a warmer air mass. There's no cold fronts? Is the warm front stationary?

I'm mean comparable to other subtropical climates. Day to day weather in Auckland isn't comparable to NW European climates.

Warm fronts/subtropical lows come from the north and depending on the source can come from any direction from NW to NE. It's usually just heavy rain or humid weather.

The weather they replace is usually stationary high pressure.

There's also warm fronts from the westerlies as well.

Subtropical storms aren't frontal; I think your terminology is confused. If it's not bringing warmer air after it passes, it's probably not a warm front.

Yep true, my terminology is confused because the terms tend to be interchangeable here, as wet weather from either system can appear much the same.

Major cold front systems in my area, can have warm fronts within them, that aren't followed by cold air due to a high pressure incursion, or the presence of a subtropical low to the north.

Warm air after the rain is a feature of subtropical lows, which is what I'm referring to. It's just moderated warm air, so the temperatures aren't that impressive - overnight lows around 20C, and daytime highs are usually moderated by sea breezes.

How is it wrong? Sure, it's not perfect. But it makes more sense than Koppen's classification.

Because it doesn't follow Trewartha's system. -probably just a simple mistake.

Isn't it an updated version of Trewartha's original layout? The new version is an improvement, either way.

Hasn't Koppen's map been updated a few times too?

THe old Trewartha map was wrong, and the new one made the same mistake -probably just poorly researched.

I would use the guidelines Trewartha used instead, which is 8 months greater than a 10C average.

I don't pay much attention to Koppen's map, although agree with his classifications.

Berlin and Munich for being cold and snowy in winter.
