How about a slight cold and cloudy day?

About "What three kinds of weather are you afraid of today's slight cold?" As follows: I am afraid of the slight cold and sunny weather, the slight cold blowing the south wind, and the slight cold "thundering".

The first image: I'm afraid a slight cold is sunny.

According to the experience of our ancestors, it is better to rain than to be sunny on the day of the slight cold solar term. If the slight cold solar term is sunny, it is not a good sign. So what are the signs of mild cold and sunny weather? Let's look at what agricultural proverbs say.

As the agricultural proverb goes, "There is no rain in a slight cold, but there is drought in a small summer". This agricultural proverb means that if there is no rain and it is sunny on the day of the slight cold solar term, then according to the experience of our ancestors, it indicates that there will be little rain in the next summer solar term and it is prone to drought.

In dog days, the head is often in the summer solar terms. If it is dry in summer, it indirectly means that there is less rain in the head. As the old saying goes, "it rains less in the head, and it rains less in the head", which means that if it rains less in the head, it indicates that it will rain less in the next three days. The dog days are the time when crops grow fastest. Once there is little rain, it is easy to cause "summer drought", which leads to serious crop yield reduction.

Agricultural proverbs also say, "A little cold is warm, and the stove is bright." Warmth means a big sun. This agricultural proverb means that if the weather is sunny on the day of the slight cold solar term, according to the experience of our ancestors, it indicates that the temperature will be lower in Tomb-Sweeping Day, and people need to keep warm to keep out the cold, which indicates that there will be "late spring cold" weather.

Late spring cold will lead to seed rot after sowing, which will lead to a large number of fruit trees falling flowers and fruits and affect wheat filling. Once there is cold weather in late spring in Tomb-Sweeping Day, it will lead to serious crop yield reduction.

Slight cold and sunny solar terms not only indicate drought in dog days, but also indicate that Tomb-Sweeping Day is prone to spring cold, so people are afraid of slight cold and sunny.

The second elephant: I'm afraid of the slight cold and the south wind.

In the slight cold solar term, under normal circumstances, the Mongolian high pressure is strong and stable. At this time, the cold air will frequently go south, so the slight cold solar term should be dominated by blowing the north wind. If the south wind blows in the mild cold season, it is not a good sign.

As the agricultural proverb goes, "A slight cold blows the south wind, and it is warm in March and September." . It means that if the south wind blows on the day of the slight cold solar term, according to the experience of our ancestors, it indicates that the weather will be warmer during the March 9 th period. As the saying goes, "It's hot in dog days, but cold on March 9th". The dog days are the hottest time in China, and March 9th is the coldest time in China. If it is warmer on March 9th, it means "warm winter".

Too warm in winter is not good for farmers. Warm winter will lead to the vigorous growth of winter wheat and the decrease of cold resistance of Wangmai. In the event of cold weather at the end of next spring, wheat will easily suffer from freezing injury and reduce production.

Secondly, too warm winter will lead to a large amount of evaporation of soil moisture, and winter crops will be reduced due to drought. In addition, warm winter will lead to the breeding of pests and diseases in the coming year, and the risk of crop pests and diseases will increase. Therefore, the south wind in the slight cold season is not a good sign for farmers.

The third image: I am afraid of the slight cold "thunder"

""It was 239 when I had a slight cold, and I was shivering with cold. "When the slight cold, the weather will be very cold. When the temperature is low, it is not easy for air to form convection. One of the necessary conditions for thunder is that air should form convection, so that air friction will thunder. If it thunders on a mild and cold day, it means the weather is abnormal.

The farmer's proverb says, "Thunder hits winter and freezes cows". It is said that there is thunder in the cold winter, which indicates that the weather will be extremely cold for some time to come. "Frozen cattle" is an exaggerated expression, which means that even frozen cattle are frozen to death.

Thundering in winter means that both cold air and warm air are moving, which is easy to form convection thunder. When cold and warm air meet, it is easy to form continuous snow and ice weather, and the weather will become very cold.

To sum up, China is an ancient farming civilization, and our ancestors summed up a lot of practical experience in long-term labor production. According to our ancestors, mild cold, sunny weather, southerly wind and thunder are not good omen.

Farmers depend on the sky for food, and the ancient productivity itself was underdeveloped. Once the grain production is reduced, it will easily lead to famine. Therefore, people in ancient times were sensitive to the change of the weather, so there was a saying that "there were three signs of slight cold and graves everywhere".
