What would be the effects of the North Pacific current on the climate of that Archipelago in darker Red on the map?

Assuming that the climate is exactly the same as just before the beginning of the industrial period and that topography does not change.

The topography of the country, excluding its bright red territories, tends to be flat with isolated but very tall mountains and volcanoes scattered around its islands, with the exception of the already existing mountains on present islands, the main archipelago besides the Aleutians and Kurils extends from at least 50 kilometers south of Kamchatka's southernmost latitude (49,09° North) down to the southernmost portion of Hawaii (18,94° North) passing by one very large island (around 34,00° North), the Kuril, Commander and Aleutian islands are also included, but their topography does not change like I said and they're just bigger.

What would be the Köppen climate map for this country? I excpect a more continental climate in the north, temperate in the middle and subtropical in the south.

    $\begingroup$ Please set your expectations. (a) The most complicated questions we receive are about climate, because… (b) Climate is ridiculously complex. Trained climatologists still can't predictably predict the weather. We're getting better, but it's monstrously complex. (c) Consequently, you're asking a very simple question about a terribly complex process. You're going to get terribly simple answers. E.G., the effect of that archipelago on the North Pacific current would be devastating due to the rise in the sea floor around the archipelago - and that would have big consequences everywhere else. $\endgroup$
