"I am most afraid of sunny days on March 9." What is the saying that it will be sunny tomorrow? Look at what the agricultural proverb says.

The phrase "I am most afraid of sunny March 9" is mainly based on agricultural production and people's life. The sunny weather in March and September is not pleasant, but extremely worrying. This is because it often indicates the climate trend in the coming year, especially the anomaly in the spring next year.

March 9 is the coldest season of the year. According to traditional cognition, there should be a strong cold wave and continuous blizzard at 3 o'clock. However, there is an abnormal March 9 weather that is even more elusive-that is, "I am most afraid of the sunny day on March 9."

In China, there is a saying that it is "cold in three or nine days, but hot in three days". Sanjiu refers to the nine days from the ninth day of the twelfth lunar month to the seventeenth, representing the coldest season of the year. Supposedly, it is the coldest weather in the north and the cold in the middle of winter in the south. Weather characteristics of Sanjiu:

The temperature is extremely low: the temperature in March and September can generally reach the lowest point of the year. Many areas in the north will be below MINUS 10 degrees Celsius, and the south will be around MINUS 5 degrees Celsius or even lower. The highest temperature during the day is also below zero.

Gale: During March 9th, cold air moved south, causing gale. The wind can reach more than five or six, and the snow on the road surface overturns, which brings great difficulties to travel.

Blizzard: How much snow falls in the north on March 9th? There may be a blizzard in the middle, resulting in extremely low visibility and traffic paralysis.

Severe fluctuation of air pressure: During the March 9th period, with the frequent southward movement of cold air, the air pressure also showed obvious fluctuation. Severe air pressure pulsation can also cause human discomfort.

"Sanjiu" custom:

When it comes to the traditional custom of March 9, we have to mention the "map of dispelling cold on September 9". People in ancient times hoped that the cold winter would pass early and the warm spring would come early to celebrate festivals, so they created pictures and dyed them with the number "998 1" every day. While recording the date, they prayed that the cold would dissipate and everything would revive.

The Topographic Map of Cold Area in 1999 has been drawn since winter. According to records, this map is generally a plum blossom map, drawing a plum blossom. It has 8 1 petal (representing 998 1 day). Dye a petal with a pen every other day. After 8 1 day, 8 1 petals have all been dyed, and spring is coming. There are many other styles besides plum blossom patterns.
