Why does school always start in September? It turns out that there is a meteorological reason!

The new school season is coming

Parents have been waiting for their children to return to school.

Are there any friends who are curious?

Why does the school start in September every year?

Instead of a prosperous spring

Sunny summer

Snowy winter?

actually

This is very important in terms of meteorology.

No rush

Let’s talk about it below

Why aren’t the other seasons suitable?

"Passionate" summer

In summer, the heat received by the ground every day exceeds the heat lost, and the daily average temperature continues to rise, reaching its highest point during the "dog days". In Wuhan, Chongqing, Nanjing, Hunan and other places in the middle and lower reaches of the Yangtze River, hot days are almost the norm. In the "steaming and grilling" weather, it is more suitable to stay at home to escape the heat than to go to school.

Summer is the rainiest time of the year and is also the flood season that the meteorological department pays close attention to . During this period, precipitation, severe convective weather, thunderstorms, typhoons and other weather conditions are frequent across the country. Secondary disasters such as mountain torrents and mudslides caused by disastrous weather are also the most common in the year. Safety is still the first priority on the way to school!

Therefore, choosing summer as the starting point for school is really inappropriate! After all, the power of heat stroke and frequent heavy rains is not to be underestimated!

Winter with “frozen hands and feet”

As winter approaches, most areas of China have entered the coldest season of the year . Waves of cold air continue to invade the south, and large-scale rain, snow, and cold waves often occur. Local extremely cold areas can even experience extreme low temperatures below -40°C. In addition, severe cold weather often gives people a bleak feeling. It is not appropriate to start school in such a bleak and cold season!

Spring with a “spring breeze”

Spring is the transition period from cold to warm seasons , and there will still be a relatively cold period during this period. However, in terms of climate, although spring is not as cool and refreshing as autumn, it still has certain advantages as a season of prosperity and revival.

Isn’t it just right for school to start in the spring?

In fact, this is also related to agricultural arrangements:

As the saying goes, "A day's plan begins in the morning, and a year's plan begins in spring." As a traditional agricultural country, my country has always had the most intensive farming schedule in spring. Farming work is very busy, with sowing, transplanting, spring irrigation and fertilization according to the seasons of different crops.

September is the harvest season, when most of the harvest is stored in warehouses. It can be a short period of rest and it is a good time to start studying.

As the saying goes, "Don't waste the farming season!" Perhaps it is because of the rhythm of farming arrangements from ancient times to the present that we have skipped spring and chosen autumn at the beginning of the school year.

Back-to-school weather checklist

It is said that a new semester brings a new atmosphere.
