Back to the subarctic... do you think the subarctic should be delineated further than it already is? How can Anchorage, AK and Churchill, Manitoba be classified the same? I'm wondering if the subarctic should be divided more finely on the basis of where the permafrost line is (at least in continental climates) - Moderate Subarctic vs. Severe Subarctic. And maybe the dividing line between Moderate subarctic and temperate continental where the average annual temperature is below 5C?

So, basically in this site, any area north of the blue line up to the tree line would be severe subarctic and any area below it to the 5C annual temperature isotherm would be moderate subarctic.

Wow, the continuous belt of permafrost goes way north of the 60th parallel in the west,
but includes the entire Hudson Bay (but not James Bay) coast in Ontario.

Scary really...
I've heard that "ice on Hudson Bay" has been responsible for TORONTO staying well below-seasonal (10 F/6 C?) for weeks-at-a-time in spring and early summer. One year our summer weather kicked in on June 25th because of ice on Hudson Bay. So cool that year, our trees were mostly bare of leaves on June 21st! (take a look at how FAR Hudson Bay is from Toronto )

"Subsea permafrost" north of NWT?

Hudson Bay must be the coldest body of water on Earth for its latitude (excluding tropical and subtropical upwellings). Only the Sea of Okhotsk may be comparable. It is on the same latitude as the Baltic Sea (near which I grew up) but the Baltic Sea proper remains ice-free most winters! Hudson Bay on the other hand is icebound 8-9 months of the year.

Hudson Bay is indeed frigid for its latitude. It's essentially an Arctic body of water at temperate latitudes. I mean they even have Polar bears that live around there! I don't even think the Sea of Okhotsk has that. I think in Asia you only find the Bears much further south than Chukotka.

Yeah I can remember reading a climatology book which stated the fact that Canada has Polar Bears at the same latitude as England has Vineyards and couldn't help cracking up at that!

Edit: Dumb censoring on here thought that a word beginning with "S" meaning laughing had the rude N word for black people in it

Seeing how "warm" winters are around 43 N in Portugal and Italy almost make me want to cry sometimes.

*I used to think there was something inherently-wrong with my latitude

Have a look at Vladivostok if you want to feel better.

I can't help but feel a bit jealous when I look at the Spanish antipodes of New Zealand cities and see how much warmer and sunnier they are (compare Auckland and Seville, for instance).

It's amazing how frigid in winter the Russian far east and Northern China are for their latitude. The city of Changchun which is inland from Vladivostok is even slightly colder than it in the winter time (average lows of around -19C in January vs. -15C for Vladivostok). Even continental climates in North America are much warmer for the latitude. For example, Fargo, ND (which has one of the most continental climates in the US) has the same average low as Changchun and it's 3 degrees latitude further north and much further inland from the sea.

In terms of Auckland vs. Seville, at least Auckland's lows are typically much milder in winter if that's any consolation.

For me, I sometimes get jealous of the British Isles which are at the same latitude as Vancouver and yet they are at least 1 to 1.5 hardiness zones higher than here.
