When is slight cold?

The slight cold solar term in 2024 is 65438+4: 49: 09 on October 6, 2024/KLOC.

Slight cold is the 23rd solar term in 24 solar terms and the 5th solar term in winter. The solar calendar of Douzhizi is 285 degrees, and the Gregorian calendar is 65438+1October 5-7, which is slightly cold, marking the official start of the season and winter. Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme. Slight cold, like severe cold, mild summer heat, severe summer heat and intense summer heat, are all solar terms indicating temperature changes.

Slight cold, like severe cold, mild summer heat, severe summer heat and intense summer heat, are all solar terms indicating temperature changes. Cold means cold, and slight cold means the degree of cold. The slight cold solar term began to form the most powerful and stable East Asian trough, and the Mongolian cold high and Aleutian low also reached the most powerful and stable period. The scale of the westerly ridge reaches the maximum, which matches the maximum intensity of the westerly wind. Although the cooling process of cold air is frequent in the slight cold season, many of them can't meet the cold wave standard.

Brief introduction of slight cold

According to China's long-term meteorological records, the slight cold solar terms are colder than the severe cold solar terms in the north, and there is a saying that slight cold is better than severe cold in the north. However, for some parts of the south, the lowest temperature in the whole year will still appear in the great cold solar terms. The slight cold in the north of China is colder than the severe cold, because the surface residual heat is relatively small, which has been completely released by the slight cold, and the temperature is minimized. The surface of the south is relatively hot, and the remaining solar terms from hot to slight cold have not been released. In severe cold, the surface residual heat is discharged and the temperature is minimized.

During the slight cold solar term, the East Asian trough developed the strongest and most stable, the Mongolian cold high and Aleutian low also reached the strongest and most stable, and the ridge scale of the westerly trough reached the maximum, which matched the strongest westerly intensity. The cooling process of cold air is frequent in the slight cold season, but few of them reach the cold wave standard. In northern China, there is a saying that slight cold is better than severe cold, which means that slight cold solar terms are colder than severe cold solar terms, which is not unusual.
