Hello and welcome to /vtwbg/!
Regarding /hag/'s climate classification, it should be noted that the coloured map has a somewhat erroneous legend - if you check the colour blind-friendly version which was what I made a while ago, you can see that the Dfa zone is actually meant to represent the humid continental climates, which include both Dfa and Dfb. In practice, you can probably assume somewhere between a third to half of the humid continental zone in /hag/ to be Dfa, with the rest being Dfb.
As for /hag/'s climate in general, the thing is that you are in the southern hemisphere, which means that the further south you go, the colder the weather is because it is closer to the south pole. As such, the warmest part of /hag/ is in the north, hence its humid subtropical north compared with the more continental south.
As mentioned by >>38845633, on Earth, the continental climates are pretty much confined to the northern hemisphere, but the lack of continental climates in the southern hemisphere is mostly because of the lack of continents in the southern hemisphere rather than anything intrinsic to the north-south distinction. Since the continents are distributed more evenly in Vitubia, the southern hemisphere has its fair share of continental climates here as well.

The alpine tundra's extent is due to a combination of its high latitude of the /uoh/ highland and the katabatic wind it generates - basically, its huge ice sheet forms a semi-permanent high-pressure zone that constantly pushes out cold wind into the surrounding lowland. While the nearby ocean and its currents can counteract the effect to a degree, the surrounding highlands are still cooled enough to be considered alpine tundra. It does not really have an Earth analogue because there are no such large ice sheets that close to the Equator - the closest we have are the Greenlandic and Antarctic coast, but those places would be freezing even without the effect of the ice sheet.
