Before summer can be recalled, autumn can't wait to come. The beginning of autumn has already passed the heat treatment, and then there is the White Dew solar term. Is today one of the twenty-four solar terms the White Dew solar term? Is it still hot after the solar term? Let's have a look.
What day is Bailu
Bailu 2018 date:
Saturday, September 8, 2018 (July 29, 1898 (year of the dog), 8 days before Bailu, 2018)
1. Bailu is the 15th solar term in the 24 solar terms of the lunar calendar. When the sun reaches 165 degrees of the Yellow longitude, Bailu is called Bailu. When the weather turns cold, there will be many dewdrops on the ground and leaves in the early morning. This is because the water vapor condenses on it at night, so it is named. The ancients used four seasons to match five elements. Autumn belongs to gold and is golden and white. Therefore, autumn dew is described as white. When you enter "Bailu", you will feel a little cool at night.
2. At this time of the solar term, as the weather gradually turns cool, the sun is still hot in the daytime. However, as soon as the sun returns to the mountain, the temperature drops rapidly. At night, the water vapor in the air condenses into small water droplets when it is cold. It is very closely attached to the green stems and leaves or petals of flowers and trees, and it is white. Especially after the morning sunlight, it looks more crystal clear, white and flawless, which is very annoying I like it, so I got the reputation of "Bailu".
Bailu sanhou
Hongyan: birds fly from north to south, big said Hong, small said wild geese.
Return of Xuanniao: swallows and other migratory birds fly south to avoid cold.
Birds raise shame: birds begin to store dry fruit grain for winter.
Is it still hot after Bailu
In fact, it will not be hot, because with the advent of cold air, many people will feel that the temperature difference between morning and night is large, and the temperature at night will drop to a very low level, but there is still sun in the daytime, which is a normal climate change.
1. Dew is a drop of water formed by the condensation of water vapor on the ground or near earth objects due to the decrease of temperature. Therefore, Bailu is actually a sign that the weather has turned cold. In the climate of the 24 solar terms in the basin of our province, Bailu has the obvious characteristics of the rapid drop of temperature, the beginning of continuous rain and the sudden decrease of sunshine, which deeply reflects the seasonal change from summer to autumn.
2. As the saying goes: 'Bailu autumn night, night cold night. 'at this time, the summer wind is gradually replaced by the winter wind, the cold air turns to attack, and the warm air gradually retreats. The cold air is gradually frequent in the south. In addition, the sun's direct position on the ground moves southward, the sunshine time in the northern hemisphere becomes shorter, the sunshine intensity is weakened, the sky is usually clear at night, and there are less clouds, and the ground radiation and heat dissipation are fast, so the temperature drop speed is also gradually accelerated.
3. "Bailu autumn night, night cold night", there is a saying in traditional Chinese medicine that "Bailu body does not show, cold dew feet do not show", that is to say, once Bailu solar term is over, you can no longer be shirtless in clothes. In addition, the weather is changeable after Bailu, especially the temperature difference between morning and evening is large, which is easy to induce cold or relapse. If you are greedy for cold food at this time, it is easier to make the function of the spleen and stomach abnormal, and damage the Yang Qi of the spleen and stomach, especially those with deficiency of the spleen and stomach.
4. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. Although the temperature in the day is still more than 30 degrees, it drops to more than 20 degrees after the night. The temperature difference between the two is more than 10 degrees. Yang Qi reaches its peak at the summer solstice, when the extremes of things turn against, Yin Qi also rises at this time.
