Explain why spring in Harbin is called short with latitude factors.

In the north of China, the solar radiation is very weak in winter, and the exposure time is short. Cold air often flows from the north, and the temperature is very low.

After the coldest period in June 5438+ 10 passed, on the one hand, the solar radiation gradually strengthened, on the other hand, the cold air force weakened, so the temperature gradually increased and the weather gradually warmed up, but the precipitation was scarce and the air was dry. After March, due to the further strengthening of solar radiation and the further weakening of cold air, the ground temperature may rise rapidly. Therefore, generally speaking, the temperature rise is the largest in March-April in northern China, that is, the temperature rise in April is obviously higher than that in March. For example, the average temperature in Beijing in March was 44℃, when the weather was still cold, and in April it was 132℃, which turned into a spring season.

Generally speaking, the spring and autumn in the north of China are particularly short, mainly because of the high latitude there, and winter comes early and goes late. Because the winter in the mid-latitude zone in the northern hemisphere is longer than that in the southern hemisphere.
