What season is the solar term of the first frost?
1. The first frost, one of the 24 solar terms, is the last solar term in autumn, which means that the weather is getting colder, and the first frost appears around1October 23rd every year. The first frost means that the weather is colder and the dew condenses into frost. "Twenty-four solar terms": "In mid-September, the essence is cold and condensed, and dew cream".
Second, after entering the first solar term in first frost, the scene of late autumn is obvious, and cold air moves southward more and more frequently. The first frost does not mean "frost", but refers to the sudden drop in temperature and the large temperature difference between day and night. The first frost is the season with the largest temperature difference between day and night in a year.
Third, the first frost solar terms are characterized by cold weather in the morning and evening, hot noon, large temperature difference between day and night, and obvious autumn dryness. During the first frost, the ground lost a lot of heat, and the temperature suddenly dropped below 0 degrees. Water vapor in the air directly condenses on the ground or plants to form tiny ice needles, and some become hexagonal frost flowers with white color and loose structure.
Fourth, the custom of solar terms: In some places in China, red persimmons should be eaten in the first frost season. In the eyes of local people, this can not only keep out the cold and keep warm, but also nourish the bones and muscles. This is a good first frost food. In some places, the explanation of this custom is that the first frost will eat shuttlecock on this day, otherwise his lips will crack all winter. At this time, people living in rural areas will climb tall persimmon trees and pick some bright and sweet persimmons to eat.
