The people in the north of the U.S. are "less friendly" than people in the south. This does not mean they are introvert, really, but they keep to themselves. I do think the climate has a large part to play in peoples behavior.
I just wonder about Asian cultures, and particularly the Japanese. Japan is a more tropical country, yet they tend to be very private people. I wonder what is the reason for that?
Subtropical to moderate is more likely...
Hokkaido can be very cold in the winter, and quite cool even in the summmer, whereas the Ryukyuan islands are definitely subtropical.
I think to classify regional personality traits according to just one variable of climate would be rather too simple a model to base typology on, but I know what you're talking about. Perhaps shifting the variable just a bit to "a number of environmental-social-industrial restraints that leave little freedom for socializing, exploring, adventuring" would affect a more encompassing result covering a broader range of peoples and cultures.
1) debilitating climate conditions that keep people indoors for an extended period of the year
2) a socially demanding, harsh, and punitive atmosphere might make people more reserved than outgoing
3) a heavily industriallized and consumption oriented society might keep the people too busy working and spending with little time-juice left for socializing--basically too busy and tired after all the job duties and spending activities
4) also the degree of industrialization might have broken down the social fabric of extened clan type families into nuclear families, childless families, 1-child families, or simply celibate individuals-- these cases are both the by-products and assets of a thriving industrialized economy
5) a society with highly developed personal entertainment--my PC, my car, my house, my anime, my manga, my playstation, etc. ?
btw: Have you noticed any substantial differences between the French speaking Candians and English speaking Canadians, and the Inuits (US or Canadian) regarding the 'introvertedness' that you've been observing ? Not in a stereotyped kind of way, but reflecting reality, of course. But generalizing is always fun; it is a general human trait to simplify when there is too little info or too much of it, or you just wanna have fun !
