It looks kind of like a biome chart. I’m probably wrong.
However, maybe it’s some kind of weather patterns

Wow, that's quite a challenge. I was curious and had a bit of time on my hands, so here's what I learned so far:
It's obviously a map showing a hierarchical classification of regions. The regions roughly correspond to climate zones, but not quite -- the yellow 63 region is merged with the eastern 62 region on all climate charts I found, forming a homogenuous region around the Hudson Bay.
There is a system called Standard Geographical Classification (SGC) used by the Canadian statistics agency that looks really similar, but uses lower classification numbers (e.g. 12 for Nova Scotia instead of the 64 we see here). The borders of the regions shown on your map also do not match Canada's Ecoregions) and none of the other geographical classification systems discussed in De Kerckhoveet al. (2017). Choosing spatial units for landscape-based management of the Fisheries Protection Program. DFO Canadian Science Advisory Secretariat Research Document. 2017. v + 44 p.. .
Given that the classifiers on the map are all in the range from 61-69, we can assume that this is a classification that spans a larger geographical area than just Canada. But using several different approaches, I could not find any page on the web that even contains 5 of the classifiers above.
OP, do you have any more metadata about this map? Perhaps even an idea whether this is about politics, geography, climate, ecology or something else? I consider this as my puzzle for the weekend now :-)
