What is the difference between cold dew and white dew .

24What is the difference between cold dew and white dew in the solar terms? The rural uncle explained very clearly, how much do you know.

The difference between cold dew and white dew is first of all in the change of temperature, as people often say: "White dew does not show the body, cold dew does not show the feet." "After the white dew, the weather becomes cooler, and the dew begins to appear, and when the cold dew arrives, the dew increases, and the temperature is lower.

Tongwei Filial Piety Aid Deed" said: "Fifteen days after the autumn equinox, the fighting finger is Xin, for the cold dew. The words are cold and want to condense.

If the cold dew coincides with low temperatures, early frost can be seen.

Su Wen: The Great Treatise of the Six Yuan Zheng Ji contains: "The five qi, the tragic order has been carried out, under the cold dew, the frost is early. "White dew and cold dew: the two "dew" are very different, and the differences in the appearance and phenology also caused the ancients to have a very different mood in the face of these two seasons.

The difference between cold dew and white dew is different time, different solar terms, different climates, and different diets.

1. The time is different

White Dew: The White Dew solar term comes from September 7 to 9 every year, when the sun reaches the yellow longitude of 165°, which is the white dew solar term.

Cold Dew: The Cold Dew Solar Term comes on October 8-9 every year, when the sun turns to the position of 195° of the ecliptic longitude, which we call the Cold Dew Solar Term.

2. The position of the solar terms is different

Bailu: The Bailu solar term is the fifteenth solar term in the twenty-four solar terms, the third solar term in autumn, the autumn old Bihuihu has just ended, and it is the transitional solar term of summer and autumn.

cold dew; The cold dew solar term is the seventeenth solar term in the twenty-four solar terms, the fifth solar term in autumn, the weather begins to get cold after the cold dew solar term, and it is necessary to wear long sleeves or thin outer book sets every day, and the temperature difference between morning and evening is large, and it is easy to catch a cold.

3. The climate is different

Bailu: The temperature is starting to drop. The Bailu solar term is the transition solar term of summer and autumn, and when it comes to the Bailu solar term, the weather begins to get cooler, the temperature difference between day and night increases, and the water vapor condenses into small water droplets near the ground in the early morning, forming "white dew" one by one.

Cold dew: The temperature is lower and the chill is gradually rising. The time of cold dew has come to October, the weather has begun to gradually turn from cool to cold, the dew on the ground is invaded by the cold air, and it is about to form frost, and the northern region is about to enter the winter climate.

4. Diet is different

Bailu: There are seasonal foods during the Bailu solar term, such as Bailu tea, Bailu wine, Bailu chicken and other seasonal foods, Chinese pay attention to the time of day, eating these foods during the Bailu solar term can nourish the body and prevent diseases.

Cold dew: When the cold dew has entered the late autumn regret posture, this is the time when the chrysanthemums are in full bloom, you can pick chrysanthemums to make chrysanthemum wine, chrysanthemum cake, chrysanthemum tea, and the cold dew is the season when persimmons are on the market, and you can also eat persimmons.

The time is different: the time of Hanlu Duanqiao is after Bailu, which is generally October 8-9 of the annual solar calendar, while the Bailu solar term is on September 7-9 of the solar calendar every year; The climate is different: the time of cold dew has arrived in October, at this time into late autumn, the climate gradually turns from cool to cold, and the white dew is the autumn tiger has just ended, this socks are still a little hot, is the transition of summer and autumn.

1. The time is different

The cold dew solar term comes on October 8-9 every year, when the sun turns to the position of 195° of the yellow longitude, which belongs to the fifth solar term of autumn; The Bailu solar term comes on September 7-9 every year, when the sun reaches the ecliptic longitude of 165°, Bailu is the third solar term of autumn, and there is an autumnal equinox between the two solar terms.

2. The climate is different.

At this time, the weather begins to gradually turn from cool to cold, the dew on the ground is attacked by the cold air, and it is about to form frost flowers, and some northern regions of our country are about to enter winter, and the Yangtze River basin region enters late autumn; The white dew solar term is the transition period between summer and autumn, when the weather begins to get cooler, the temperature difference between day and night increases, and the natural phenomenon of "white dew" can be seen in the early morning.

Bailu and Hanlu feel very similar to Shinmori when they hear it, but the two solar terms are at different times, and Bailu and Hanlu are both autumn solar terms in the 24 solar terms, but Bailu and Hanlu are not the same solar term. The white dew solar term comes between September 7 and 9 every year, and the cold dew solar term comes between October 8 and 9 every year. After the white dew, the weather becomes cooler, and dew begins to appear, and when the cold dew arrives, the dew increases, and the temperature is lower.

Slippery acres. Bailu is the solar term of the eighth month of the lunar calendar, which indicates that the weather has turned cooler. It is evident that the hot summer has passed and the cool autumn has arrived, because although the temperature during the day still reaches 30 degrees Celsius, after night, it drops to 20 degrees Celsius, and the temperature difference between the two is more than 10 degrees Celsius.

Cold dew is the solar term of September of the lunar calendar, because the temperature becomes cold, so that the water vapor condenses into dew, so it is called cold dew, at this time has entered the late autumn season, the earth is a bleak scene, the cold is pressing, the bird is no longer known for the ear, the insect is no longer singing, the fallen leaves are all over the ground.

White dew and cold dew are both autumn solar terms among the 24 solar terms, but white dew and cold dew are not the same solar term. The overall temperature of the white dew tea season is about 15 26, and the cold dew tea season is about 11 21, and the air humidity during the cold dew season is low and relatively dry.

White dew and cold dew are both autumn solar terms, and the first difference between them is that the time is different. When the sun reaches the ecliptic longitude of 165°, it is the white dew solar term.

Of course not, these are two different solar terms. The difference is that the time is different, the position of the solar terms is different, the climate is different, and the dietary conditions are different.
