What kind of climate change does it mean to be in the heat today?

After the summer solar term, it means that the hot weather has come to an end and the heat is about to stopOn the one hand, this year's "dog days" have not passed, on the other hand, under the influence of the "autumn tiger", after the heat, there will continue to be a period of hot weather, but the temperature in the morning and evening has decreased, but at noon, there is a high temperature of more than 30 degrees.

Climatic characteristics: Temperature drops:

The end of August and the beginning of September are not enough to describe the beginning of the summer season as the temperature begins to drop. Falling temperatures are just one of the phenomena. The reason behind this phenomenon should first of all be that the direct point of the sun continues to move southward and the solar radiation weakens; Second, the subtropical high retreated southward by leaps and bounds, and the Mongolian cold high began to be eager to try, punching and kicking, showing its edge.

Autumn is high and cool: the cold and high pressure that began to affect our country, under its control, the formation of sinking, dry cold air, first announced the end of the rainy season in Northeast China, North China, and Northwest China, and took the lead in starting the most beautiful weather of the year - autumn high and cool. During the summer season, it is only the Northeast and Northwest regions that really enter autumn.

However, whenever the cold air affects our country, if the air is dry, it often brings windy weather, and if there is warm and humid air in the atmosphere, it often forms a decent autumn rain.

Whenever a storm is over, especially after rain, people will feel a noticeable cooler. Therefore, there is a saying: "an autumn rain (wind) and a cold".

In the southern part of the Yangtze River and Huaihe region, there is also a possibility of a large precipitation process. The temperature drops significantly, the temperature difference between day and night increases, and the sun is in the sky after the rain, people often do not adapt to the cold and hot changes at the turn of summer and autumn, and it is easy to cause diseases such as respiratory tract, gastroenteritis, and colds if they are not careful, so there is a saying of "eventful autumn".

The beginning of autumn has arrived, and the summer is not far away. The summer heat follows the beginning of autumn, and the beginning of autumn and summer are one of the 24 solar terms. The beginning of autumn represents the beginning of autumn, ranking thirteenth in the solar terms, and is the first festival of autumn, the seventh month of the lunar calendar.

The summer heat represents the summer heat gradually disappears, the autumn coolness is obvious, it ranks 14th in the solar terms, it is the first gas in autumn, the middle of July on behalf of the lunar calendar, it is on August 23 or the day before and after the solar calendar, and the solar yellow longitude is more in the middle or late July from the lunar calendar, and the solar yellow longitude is at 150 degrees.

Where the heat is located, here is the meaning of going out and stopping, and the summer is hot. Dealing with the summer heat is to get out of the hot summer, stop the heat, the heat gradually disappears, and the autumn coolness is obvious. The winter is cold, the summer is hot, and the end is after the autumn.

The water in the beginning of autumn is cold for three minutes, and when it comes to the summer, it is obvious that it is cool in the morning and evening. It's cool in the summer, and it's cold to the wall. It's cold and cold, which is saying that it's morning and evening, and it's still hot at noon.

The beginning of autumn is not autumn, after the cool white dew, the summer is in the beginning of the autumn white dew, there is summer heat and autumn cool. The temperature difference between day and night is large, to prevent cold and discomfort, summer and autumn cool, the change of seasons is obvious, not adaptable, especially the old and young, etc., resistance, immunity is weak, it is very easy to cause illness due to seasonal changes, the temperature is cold, hot, dry and wet.

I come to this question. It is the fourteenth of the 24 solar terms. Dou Zhi Wu (southwest); The ecliptic longitude of the sun reaches 150°; It is held on August 22-24 of the Gregorian calendar every year.

The heat is "out of the heat", which means to leave the heat. At the end of the summer, the direct solar point continues to move southward, the solar radiation weakens, the subtropical high also retreats southward, the temperature gradually drops, and the heat gradually disappears. The summer heat means that the scorching heat is coming to an end, and although it is still hot, it is already on a downward trend.

Hope it helps, thank you!

Due to the influence of short-term hot weather, there is still a continuous high temperature after the summer heat, although there is no summer heat, it will still be hot and dry, and the weather will turn from hot to sultry. The summer heat is not only different from the small heat, the big heat, but also different from the small cold and the big cold solar terms, which represents the climate change from hot to sultry. The weather is characterized by dry, muggy.

The arrival of the summer also means entering the second half of the Shen month of the Ganzhi calendar.

In ancient China, the heat stroke was divided into three phases:"An eagle is a sacrificial bird; Second, the heaven and the earth are the beginning; Three Hou Henaideng. "During this solar term, the eagles begin to hunt birds in large numbers; All things began to wither; "Hoenaiden"of"He"It refers to the general term of millet, millet, rice, and sorghum crops"Deng"That is, the meaning of maturity.

In late August, the average daily temperature in southern China may be below 23 for more than 3 consecutive days, which affects the flowering of hybrid rice.

However, since South China is still basically controlled by the summer monsoon during the summer season, there are often weather with the highest temperature higher than 30 in the western part of South China and higher than 35 in the eastern part of South China. In particular, the low-altitude areas along the Yangtze River are more felt in the years when the drought continues"Autumn Tiger"of the aftermath. The Northwest Plateau enters the summer and autumn in the middle of nowhere, and the altitude above 3,500 meters has shown the scene of early winter, the pasture grass is gradually withering, and the frost and snow are increasing day by day.

Farming arrangement. After the summer heat, the temperature difference between day and night in most parts of China becomes larger. Warm days and cool nights are very beneficial to the production and accumulation of dry matter in crops, and crops mature quickly. There is a folk saying that "the summer field changes overnight".

The early and middle rice in the Huanghuai area and the south of the Yangtze River are ripe and harvested, and the rainy weather at this time is very unfavorable. For the single-season late rice that is in the stage of young panicle differentiation, abundant rain is particularly important, and timely irrigation should be carried out in case of drought, otherwise it will lead to small panicles and high empty shell rate.

The summer heat is the early stage of the change of rainfall distribution in South China from more in the west and less in the east to less in the east and less in the west. At this time, the rainfall in central South China is often the second highest of the year, more than during the Great Heat or White Dew. Therefore, in order to ensure the use of water for farmland in winter and spring, it is necessary to conscientiously do a good job of water storage during this period.

In the plateau area, there will be continuous rainy weather from summer to autumn, which is not conducive to agricultural and animal husbandry production. Most of the southern part of our country is also the busy season for harvesting medium rice. In normal years, the sunshine in South China is still relatively sufficient, except for the western part of South China, there are not many rainy days, which is convenient for medium rice cutting and cotton spitting.

The summer heat is a sign of the cooler weather. After the summer heat, it is hot at noon, cool in the morning and evening, and a large temperature difference is formed between day and night. The climatic characteristics of "one autumn rain and one cool" are obvious.

Even if it is hot during the day, at night, the weather will cool down, and the pain of summer heat is not as severe as in midsummer. In the southern region controlled by the subtropical high pressure, people who have just felt a trace of autumn coolness often feel the hot weather again at the end of the summer, which is a veritable "autumn tiger".

Attention needs to be paid during the summer season:

In the summer season, the climate is dry, and people's ** will become tight, and even peeling and scaling, dandruff will become more, lips will be dry, and the throat will be dry, which is called "autumn dryness" by folks. At this time, the diet should be light, eat less food that is too greasy, and the hot and cold food should also be moderate.

At this time, you can eat more foods that nourish the yin and moisturize the lungs to deal with "autumn dryness", such as multigrain porridge, red date porridge, purple potato porridge, lotus seed white fungus porridge, lean meat porridge, sesame, honey, lily, almonds, dairy products, etc.

The weather changes in the summer season, that is, the morning is cool and the evening is cool, and it is still relatively hot at noon, at that time, most people are not used to this kind of weather, and they will catch a cold, and it is actually easy to catch a cold in the autumn, so if you are in the summer season, you must pay attention to your body.

It is relatively cold in the morning, and the weather will become very hot at noon, and slowly in the evening the temperature will slowly begin to decrease again, which is the weather change in the summer season, in fact, it is almost autumn.

It is the 14th of the 24 solar terms. Temperatures are characterized by a drop in temperature. A weather when the temperature turns from hot to cool is excessively solar term, and after entering the summer solar term.

People will feel that the temperature is starting to drop significantly. People will feel the heat again during the summer season, which is called the autumn tiger, and can also be exposed to thunderstorms.

The weather changes in the summer season are generally hot at noon, cool in the morning and evening, and the temperature difference between day and night is large, and the temperature will gradually decrease with the arrival of autumn rain.

The summer heat is after the beginning of autumn, which is the second solar term of autumn. "In the summer" does not mean that it is in the literal sense of "in the summer", but that the heat ends here. The characteristics of summer weather are hot at noon, cool in the morning and evening, and the temperature difference between day and night is large, and the temperature will gradually decrease with the arrival of autumn rain.

In the north, after this solar term, the summer humidity is gradually replaced by the autumn dryness. For much of the south, the heat and humidity are still intense. Therefore, in the summer, the north should pay attention to nourishing yin and nourishing the body, and the south should pay attention to the warmth and dampness.

The weather changes during the summer season, mainly representing the end of the hot weather and the arrival of a cool autumn.

The climate during the summer vacation is characterized by hot daytime, cool morning and evening, large temperature difference between day and night, low precipitation, and low air humidity. In late August of some years, the average daily average temperature of South China may be below 23 for more than 3 consecutive days, the temperature drops significantly, the temperature difference between day and night increases, and the sun shines in the sky after rain.

In the summer season, every day is changeable, sometimes sunny and sometimes rainy, and there are more convective weather, but yes, it is also an autumn rain and a cool, and slowly the weather will become cooler.

The main feature of the weather change in the summer season is that the temperature difference between morning and evening is very large, the temperature in the morning and evening is relatively low, and then the temperature at noon is relatively hot, and the temperature difference is very large throughout the day.

For the summer season, the temperature gradually drops. So the radiation of the sun will be weakened. For autumn, autumn is crisp and the weather is drier, and cold air will come.

So after this season, we will also do some cold protection, after all, an autumn rain, a cold gradually becomes colder. Natural gas changes very quickly.

In summer, the heat is unbearable, especially in some places where the temperature will reach 40, at that time it will be like a barbecue when you go out, and you must always turn on the air conditioner at home, otherwise it is a sauna. Especially dog days, which are the hottest time of the year in summer. After the dog days are over, we will enter the summer solar term, which means to get out of the heat, which means to get out of the heat and leave the heat.

Therefore, the temperature will tend to get cooler after the summer solar term. So what is the general climate in the summer?

Generally speaking, the climate characteristics of the summer solar term are hot during the day, cold in the morning and evening, large temperature difference between day and night, little precipitation, and low air humidity. In the summer heat, the average temperature is usually about lower than that of the beginning of autumn. Occasionally, the average daily temperature in western South China may be below 23 for more than three consecutive days in late August, which affects the flowering of hybrid rice.

The heat in South China is basically still controlled by the summer monsoon, so there will be a maximum temperature higher than 30 in western South China and a maximum temperature higher than 35 in eastern South China.

After the summer season, the temperature will slowly drop and the transition to cooler weather begins. But it will not cool down immediately, and there will be a short-term warm-up stage in the middle, which is what we often call the autumn tiger, and the summer solar term is just within the time period of the autumn tiger, so there is still a little bit of summer heat after the summer solar term. The summer is the 14th solar term, and the summer is also called the summer heat, which means that it is the hottest time, usually on August 22 and 24 of the Gregorian calendar, and the time of the autumn tiger is uncertain, but it is usually between August and September of the Gregorian calendar.

1. Eat sour or not spicy The front taste of sour orange has the function of moistening the lungs and astringent, and what is needed in autumn is to protect the lung yin. Therefore, avoid or eat less spicy barbecue foods at this time, including chili, pepper, cinnamon, ginger, onions, and wine, especially ginger. These foods are hot and lose a lot of water during cooking.

Especially after the end of the high temperature, the weather begins to dry, which will aggravate the damage of autumn dryness to the human body.

2. Eat hot and not cold The temperature difference between morning and evening is large in the summer solar term, not only to keep warm, but also to pay attention to diet, do not eat too much cold food. Because autumn is coming gradually, and people are prone to some common diseases at this time, it is better to eat more warm foods in your diet, which is good for the body.

3. Eat "fruit" and not "melon" "Autumn melon is bad for belly", some delicious melon balls are mostly cold, and eating too much will damage the spleen and stomach, so eat less. But some fruits can be eaten more. For example, pears moisturize the lungs and can dispel phlegm and cough, and are the most recommended fruit in autumn.

Apples are rich in vitamins and potassium, which not only benefit people with cardiovascular disease, but also prevent diarrhea.

After the heat, the next solar term is white dew. Bailu is one of the 24 solar terms of the lunar calendar, and when the sun reaches 165 degrees of yellow longitude, the Bailu solar term is crossed. Bailu is the third solar term of autumn, indicating the end of the Mengqiu season and the beginning of the mid-autumn season.

Dew is a drop of water formed by the condensation of water vapor on the ground or near-Earth objects due to a decrease in temperature. Therefore, white dew actually indicates that the weather has turned cooler. At this time, people will clearly feel that the hot summer has passed, and the cool autumn has arrived.

The temperature difference between day and night can reach more than 10 degrees.

A brief introduction to the Bailu solar terms:Bailu is the fifteenth solar term of the year, and the ancients in China divided Baipei Zilu into three phases, namely: "One waits for the wild goose to come; 2. Migratory birds; Three migratory birds are shy.

It is said that the white dew solar term is the wild goose and swallow waiting for the migratory birds to fly south to avoid the cold, and the birds begin to store the liquid fruit grain in the dry branches for winter. It can be seen that the white dew is actually a symbol of cooler weather.
