The first frost in 2023 is 65438+1October 24th.

The first frost is the eighteenth of the twenty-four solar terms and the last solar term in autumn. Every year around Gregorian calendar1October 24th, when the sun reaches the longitude of 2 10 degrees, it is the first frost in the 24 solar terms. According to the 24 solar terms, in mid-September, the air settles and condenses, and dew turns into frost. This is the first frost, which means that the weather is getting colder and colder, and the dew has turned into frost.

The first frost is the last solar term in autumn and the transition from autumn to winter. On the ground in late autumn, there is a lot of heat dissipation, and the temperature suddenly drops below 0. The water vapor in the air of frosted plants directly condenses on the ground or plants to form tiny ice needles, and some become hexagonal frosted flowers with white color and loose structure.

The first frost solar terms are characterized by cold weather in the morning and evening, hot weather at noon, large temperature difference between day and night, and obvious autumn dryness. As far as the national average is concerned, the first frost is the season with the largest temperature difference between day and night in a year. After entering the first first frost solar term, the cold air activities affecting our country became more and more frequent, and the temperature difference between day and night increased rapidly.

During the first frost, it usually lasts from late June 10 to early October110. With the dry and cold air gradually dominating the whole country, the warm and humid air is marginalized, and many weather with the characteristics of summer and early autumn exits, so the weather is relatively simple. Before and after beginning of winter, there were often strong winds and cool weather, and some places entered winter in a short time.

Second, prevent autumn depression: in late autumn, the weather is getting colder, flowers and trees are turning yellow, leaves and fruits are falling, and everything is bleak, which is easy to cause anxiety and make people feel depressed and depressed.

Three precautions against autumn cold: the first frost and solar terms, the sudden drop in temperature, the elderly are prone to diseases such as old cold legs, and chronic bronchitis is also prone to recurrence or aggravation, which is also the peak period for the recurrence of chronic gastritis and gastroduodenal ulcer. This time node is no longer suitable for autumn freezing. For the elderly with poor resistance, it is necessary to increase or decrease clothes on time to avoid the invasion of damp and cold pathogens and lead to illness.
