Which place is colder, Ottawa or Harbin? ! ? !

Ottawa is low, and obviously much lower! Mainly the problems of ocean currents and topography:

Here I can give you a comparison of several cities in the same latitude, so that you can understand the great influence of geographical features-Paris (48 degrees north latitude, the northernmost), Ottawa (45 degrees north latitude) and Harbin (44 degrees north latitude).

1, ocean current-the ocean current in the northern hemisphere is counterclockwise, so the ocean current on the west coast of the ocean is a cold current from the north;

A) The west coast of the ocean is much colder than the east coast of the ocean-the lowest temperature in Paris is +4℃ in winter, and it is-20℃ in Harbin, Ottawa, and the cold year in Ottawa can last for 30℃.

B) The destructive power of the Atlantic cold current is greater than that of the Pacific Ocean-the Atlantic cold current comes from the Arctic Ocean seriously, and the temperature of the Arctic cold current, as you know, is blocked by the Bering Strait. There are not many currents in the Arctic Ocean, mainly their own currents, and the temperature is still a little higher than that in the Arctic Ocean.

2. Topographic factors-there is a mountain in the north that blocks the wind.

A) At least there is a Daxinganling Mountains in the north of Harbin, which can stop the Siberian cold current. When it passes through the mountains, the force of the cold current will weaken.

B) There is a Ma Pingchuan in the north of Ottawa, and the cold current from the Arctic Ocean can almost sweep all the way to the south of the United States. The power can be imagined.
