What are the characteristics of the climate in northern China?

Spring in northern China is relatively short, usually less than two months. For example, the spring in Beijing is April 1 ~ 5 to May 2 1 ~ 25, in Shenyang it is April 2 1 ~ 25 to June10 ~/4, and in Harbin it is April 26 ~ 30 to June 20 ~ 24. It can be seen that in this area, when the stoves needed in winter are removed, the arbor needed in summer will soon be set up.

Since the season is determined by the temperature, the vertical speed of the temperature can determine the length of the season. 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. Since the coldest period of June+10 in 5438 passed, on the one hand, the solar radiation was gradually strengthened, on the other hand, the cold air force was continuously weakened, so the temperature gradually increased and the weather gradually became warmer, 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 can 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 4.4℃, when the weather was still cold, and April was 13.2℃, which turned into a season of spring blossoms.

In spring, there is still not much precipitation in this area. It's sunny most of the time, the air is dry, and the solar radiation continues to strengthen. The heat absorbed by the ground naturally increases rapidly, and the temperature also skyrockets. After less than two months, summer began. For example, the average temperature in Beijing reached 20.2℃ in May and rose to 24.2℃ in June. So the spring in the north is generally shorter.

In the same way, as the hottest period in July passed, the solar radiation gradually weakened and the cold air force continued to increase, so the temperature gradually decreased, and the maximum decline was from 10 to1. For example, the average temperature in Beijing in June 5438+ 10 was 12.5℃, and it dropped to 4.0℃ in June 5438+065438+ 10, which is already a cold winter 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.
