Help me sum up the weather in Changchun all year round.

Changchun belongs to temperate monsoon climate zone, temperate mixed forest and temperate deciduous broad-leaved forest zone. The climate is similar to that at home. Winter is cold and dry, and summer is hot and rainy. Compared with home, because the latitude is high (the sun's altitude angle is about 6.5 degrees lower than home) and it is close to the wind source in winter, the temperature is slightly lower than home (the average temperature in winter is-17 degrees Celsius, and it is about 20 degrees Celsius in summer), so it is relatively comfortable. Affected by the northwest and southeast monsoon, the precipitation variability is large. Especially, the winter wind is very close to the Mongolian-Siberian high, and the northwest dry cold wind originating from the Mongolian plateau almost ignores the blocking effect of Daxinganling, which has a great influence on Changchun, so there is little precipitation in winter, so pay attention to cold protection. In summer, due to the blocking effect of Changbai Mountain and the influence of near-mountain foehn, it is difficult for Changchun City, which is on the leeward slope, to get warm and humid air flow from the Pacific Ocean. Southeast wind turns into dry-hot wind across Changbai Mountain, with less precipitation in summer. So the climate may be dry, and the city is not adjacent to the tributary of Songhua River, so the water may be less than that at home, which is almost negligible. It is windy at home and there is not much water. Changchun is close to Changbai Mountain, and the scenery is not bad. ...

Generally speaking, in theory, the climate is similar to that at home. Actually, look for yourself. Does Jiefang truck run well? I have confidence in you!
