Why does it always rain during the Mid Autumn Festival, and does it often rain in the fall?

Because of the Bailu solar term, it has the meaning of widening the temperature difference between day and night and increasing the condensation of dew, and the Bailu solar term also indicates the beginning of autumn.

In the rural proverb about the Bailu solar term, there is a saying that "Bailu is single, the underground is not dry", which means that the day of the Bailu solar term, coinciding with the single day of the lunar calendar or a double day, has a certain role in the next weather, if the Bailu solar term catches up with the single day, it also indicates that the later period will be rainy weather, because it often rains and the ground will not be dry.

As the saying goes: August 15 rains, 45 days of rain, the August 15 referred to here is the Mid-Autumn Festival, which means that on the day of the Mid-Autumn Festival, once there is a rainy weather, then there may be 45 consecutive days of rain in the next month, which is equivalent to a month and a half without good weather, using this exaggerated statement, but also to remind people to pay attention to the weather changes in the future.

2021 White Dew Solar Term

The Bailu solar term in 2021 coincides with the first day of the eighth month of the lunar calendar, which means that the Bailu solar term catches up with a single day, which indicates that there may be more rain this autumn. Looking back now, this proverb in the countryside has long been a foreshadowing, and the continuous rainy weather in many places also confirms that there is still some truth in this proverb.

The arrival of the summer season means that the summer season is coming to an end, and the temperature will gradually drop. In the summer solar term, there is a saying in the countryside that "the summer is drenched on the head, and the eighteen rivers fall", and its meaning is also very easy to understand, that is, once the rain wets the hair on the day of the summer solar term, there will often be more rain in the future.

Of course, if water is evaporated, there must be rain, which is an indispensable process of the earth's atmospheric circulation. The water on the earth's surface is first evaporated, forming cumulonimbus clouds or water vapor, which will move to the sky with the movement of the atmosphere, and will fall under certain conditions. Clouds or water vapor generally move with the wind, including the monsoon, eastern China is an obvious monsoon area, in summer blowing southeast wind, the wind blows from the ocean, containing abundant water vapor, so it forms a high temperature and rainy climate.

Generally speaking, rain is necessary and good, because water is the source of life, and without rain, neither agriculture nor industry can be carried out, and we will not be able to survive. But sometimes, too much precipitation will bring flooding, which is not good, but this is also the law of nature, precipitation can bring us benefits, of course, there may also be disadvantages, which cannot be avoided, can only be prevented by certain methods.

In the Mid-Autumn Festival, the western Pacific subtropical high retreats southward, the rainy season in North China ends, the flood season ends in South China, and the Huaihe River Basin enters the rainy period in autumn, the temperature decreases during this period, and the precipitation is more in a short period of time, and the weather becomes sunny after the precipitation, the temperature is lower, and the autumn in the sense of the monsoon begins.

During the Mid-Autumn Festival to the National Day this year, there are many cold air moving south, and at the same time, the southern parts of the Yangtze River and South China are controlled by warm and humid airflows, and the cold and warm converge to form a long period of rainy weather.

It is necessary to divide the region! Is the whole world down? Natural phenomenon.

No. Entering autumn, it means that rainfall, storms, etc. tend to drop or decrease.

Autumn is one of the four seasons of "Spring, Summer, Autumn and Winter". In terms of modern meteorology, autumn falls on August 23 (summer heat) and November 20 (light snow) in the north temperate zone, and autumn in the southern temperate zone falls on February 19 (rain in the northern hemisphere) and May 21 (small manchu in the northern hemisphere). In China, it is traditional to take the "beginning of autumn" of the 24 solar terms as the starting point of autumn and the end of the beginning of winter.

Autumn means that rainfall, storms, etc. tend to decline or decrease, and everything in nature begins to grow from lush to mature. The climate in autumn is divided into two phases, the early autumn is "muggy", and the mid-autumn tends to be "dry" and "cool".

It rains in both spring and autumn, and it seems to rain as soon as the season changes, and in winter it rains a lot. Spring and autumn are very short, only 1 to 2 weeks, hehe, for example, it often rains during the National Day now, and it doesn't take long after the rain to wear thick clothes.

Depending on the area, some have a lot of rain and some don't.

Because the subtropical high, which should have weakened and retreated southwards in autumn, was abnormally strong and entrenched in the southern part of the Yangtze River, causing the southward cold air and warm air mass to converge on its north side, forming a stable frontal rain band, so it was cloudy and rainy.

Rain is the water droplets that fall from the clouds, the water on the surface of the land and the sea evaporates into water vapor, the water vapor rises to a certain height and then becomes small water droplets when it is cold, these small water droplets form clouds, they collide with each other in the clouds, merge into large water droplets, and when it is too big for the air to support, it falls from the clouds and forms rain.

The subtropical high, which was supposed to weaken and retreat southward, was abnormally strong and entrenched in the southern part of the Yangtze River, causing the southward cold air and warm air mass to converge on its north side, forming a stable frontal rain band, resulting in continuous rain.

Rain is the water droplets that fall from the clouds, the water on the surface of the land and the sea evaporates into water vapor, the water vapor rises to a certain height and then becomes small water droplets when it is cold, these small water droplets form clouds, they collide with each other in the clouds, merge into large water droplets, and when it is too big for the air to support, it falls from the clouds and forms rain.

As rivers, rivers, lakes, and seas are exposed to the sun, water becomes water vapor. The water vapor rises and turns into small droplets, and finally into clouds. The small water droplets or Xiaoice crystals that make up the cloud are supported by the air flow below, and the rising air flow is constantly transporting the water vapor below the cloud to the cloud.

The small water droplets and Xiaoice crystals in the cloud collide with each other in motion, and the volume will increase. The water droplets in the lower layer of the cloud gradually become larger, and as the volume of the ice crystals in the upper layer of the cloud increases, the water droplets fall between the droplets in the lower part of the cloud layer, and the water droplets become larger and larger. When these droplets are so big that the updrafts can't hold them, it rains.

There are four seasons in a year, summer to hot, winter to cold And in spring and autumn is the season of alternating cold and warm cold and warm air In autumn, the cold air in the north is coming, and the earth's ecliptic longitude can still get enough heat from the sun to compete with the cold air at this time, and the continuous autumn rain is coming.

The Mid-Autumn Festival is supposed to be a happy day to go out and play, but I heard that there will be heavy rain during the Mid-Autumn Festival, what does it mean when it rains on the day of the Mid-Autumn Festival?

Does it rain during the Mid-Autumn Festival.

From the night of September 17th to the 20th, China's rain showed a gradual increase and enhancement trend, the eastern part of Northwest China, the eastern part of Southwest China, Jianghan, Huanghuai, North China, Northeast and other more than 10 provinces (cities) will appear from west to east Heavy rainfall, the rainfall process is dominated by stable rainfall, the rainfall affects a wide range, affects many areas, rainfall is large, and the rainfall period coincides with the Mid-Autumn Festival holiday, which requires special attention.

What does it mean when it rains during the Mid-Autumn Festival.

For the Mid-Autumn Festival rain, there is no special statement, but the rain will have an impact on the harvest of crops, such as the Northeast region, at this time the peanuts in the field have been harvested, are drying in the ground, if you don't think of some measures in advance, it will be very troublesome, because the rain on the Mid-Autumn Festival indicates that there will be more rain in the next few days.

This is because in the vast northeast region, a large amount of rice is grown, and after the 15th day of the seventh lunar month, there is very little heavy rain in the crisp autumn weather. The time to the Mid-Autumn Festival is also the grain filling period of rice, if it rains at this time, the rice will be too waterlogged, and the rice grains will be easy to break during processing, which will reduce the income of farmers. In addition, before and after the Mid-Autumn Festival, the rice has been full of grains and heavy rice ears, and if it encounters autumn rain, it is easy to lodging, which will also cause a certain amount of yield reduction.

What to do during the Mid-Autumn Festival.

The Mid-Autumn Festival is mainly to eat and drink, especially the ceremony to put on a variety of offerings and incense tables, the sacrifices to have watermelons cut into lotus shapes, moon cakes, making moon cakes is one of the things that ancient people must do in the Mid-Autumn Festival.

Traditional food eaten during the Mid-Autumn Festival.

There are many traditional foods to eat during the Mid-Autumn Festival, such as mooncakes, which are the main traditional food of the Mid-Autumn Festival, symbolizing the good wish of reunion; The Mid-Autumn Festival is the time when osmanthus is in full bloom, and osmanthus cake is made with osmanthus to taste crisp and sweet, clear heat and fire; The Mid-Autumn Festival is to commemorate Wu Zixu, the general of the Chu State, and it is of great historical and cultural significance.

Autumn Rain is the third text in the third group of the first volume of the primary school Chinese third grade of the curriculum standard experimental textbook. This is a very lyrical prose, called Writing Autumn Rain, but actually writing about autumn. The content of the texts is rich and colorful.

The author grasps the characteristics of autumn and writes about the colorful colors of autumn, the scene of harvest, and the scenes of various animals and plants preparing for winter in late autumn. Among them, the autumn rain is a clue that skillfully strings together the many scenes of autumn, bringing out a beautiful, harvesty and joyful autumn as a whole.

Of course it will rain in autumn, this is well known. Let's take an example: two regions are cold and hot at the same time, and when the wind blows towards the junction of the two places, rain may form.

Generally, the temperature of the two places is basically stable (population, city, forest and other terrain are the determinants of the law), and this wind is the law we are looking for, if it is a mountainous area, it is relatively stable, because the wind direction is generally relatively stable in this area. In some areas with more chaotic terrain, there are too many factors that affect the direction of the wind, for example, a car will bring a gust of wind, and a convoy will form one"Wind source".Multiple wind sources can form the determinants of wind direction in a region.

Generally, thunder occurs only when it is a thundershower. Thundershowers are formed by the extreme heat of summer, when there is a strong convection of the air in a localized area, causing a large amount of hot and humid air to rise violently, causing cumulonimbus clouds.

Thunder also occurs only in summer due to the strong convection that produces cumulonimbus clouds, which only occurs in summer.

The clouds cover the moon on the fifteenth day of August, and the snow lights up on the fifteenth day of the first month.
