Meteorological composition

There is a lot of knowledge and concern about meteorology. Below, I collected and sorted out the composition about meteorology for everyone. Welcome to read and learn from!

Composition 1 About Meteorology: Although the average daily temperature in the vast areas east and south of the Beijing-Taiyuan-Chengdu-Guiyang line in China and the Tarim Basin in Xinjiang is still above 22 degrees Celsius, it is in summer, but the cold air in the south is increasing and the temperature is gradually decreasing.

In ancient China, the summer heat was divided into three stages: "The eagle is a sacrificial bird; Second, wait for the beginning of heaven and earth; Three Hou Wonaideng. " In this solar term, eagles began to prey on birds in large numbers; Everything began to wither; "Henaideng" refers to millet, millet, rice and sorghum crops, and "Deng" means maturity.

Summer is a solar term reflecting the temperature change. "Chu" means to hide and die, and "early summer" means that the hot summer has passed.

According to the astronomical almanac of China published by the National Astronomical Observatory, the exact time of summer this year is August 23rd 19: 00 and 2 1: 00. Astronomical experts said that the intense heat means that the hot situation in most parts of China will turn for the better and the weather will get colder, but the afterglow of the "autumn tiger" should not be underestimated.

Zhao Zhi Heng, an expert in astronomy education and director of Tianjin Astronomical Society, said that long summer is the 14th solar term among the 24 solar terms, and the sun reaches 150 degrees on August 23rd or 24th every year. "Twenty-four solar terms" said: "Go, go, the heat is over." "Out" means hiding and ending. "Summer" means that the hot summer is coming to an end, because the dog days are over or coming to an end.

Zhao Zhi Heng said that although the heat in summer is fading, the weather in autumn is not really cool, and there will be high temperatures above 30℃ in some parts of China.

Generally speaking, the average temperature in summer in South China is 65438 0.5℃ lower than that in early autumn. In late August of some years, the average daily temperature in western South China may be lower than 23℃ for more than three consecutive days, which will affect the flowering of hybrid rice. However, because the summer high temperature in South China is still basically controlled by the summer monsoon, there are often days when the highest temperature in western South China is higher than 30℃ and that in eastern South China is higher than 35℃. Especially in the low-altitude areas along the Yangtze River, in the year when the summer drought lasted, the "autumn tiger" was felt. The northwest plateau has entered summer and autumn is strong. At an altitude of more than 3,500 meters, it has already shown the scene of early winter, with grass gradually withering and frost and snow increasing.

Summer is the early stage of the transformation of rainfall distribution in South China from more in the west to less in the east. At this time, the rainfall in central South China is often the second highest point in a year, which is more than that in hot summer or white dew. Therefore, in order to ensure farmland water use in winter and spring, we must do a good job of water storage in this period. There will be continuous rainy weather from summer to autumnal equinox in plateau area, which is not good for agriculture and animal husbandry production. At this time, most of southern China is also a busy season for harvesting mid-season rice.

Generally, during the summer solar term, the sunshine in South China is still abundant. Except for the western part of South China, there are not many rainy days, which is beneficial to mid-season rice cutting cotton and spitting. However, in a few years, just like Fu's poem, "The dog days have passed, and the sun turns into rain", the autumn rain will come ahead of time. Therefore, we should pay special attention to the weather forecast, make full preparations, seize every sunny day, and seize the opportunity to do a good job of grabbing a bumper harvest and basking in the sun.

Composition 2 on meteorology: In autumn, autumn wind bursts, the atmosphere is bleak, sometimes sultry, sometimes rainy and humid. In such a drastically changing environment, if you feel unwell occasionally, you will easily suffer from "autumn weather allergy", which is characterized by lethargy, fatigue, abdominal distension, insomnia and dreaminess, memory loss, dizziness, palpitation and sweating, irritability and anxiety, accompanied by old pain attacks.

Modern medicine has proved that a single pathogenic factor is difficult to make people sick, and it must be combined with climate factors, that is, climate is the decisive factor that causes diseases and aggravates disease symptoms. Climate mainly depends on meteorological factors such as temperature, humidity, air pressure, wind speed, wind force, rainfall, sunspots and cosmic rays, among which temperature, humidity and air pressure are the decisive factors. These meteorological elements are reflected to the brain through human skin receptors, so that the pituitary gland secretes corresponding hormones to maintain the relative balance of the body before and after the weather changes, so that people will not suffer from "meteorological allergies." The climate changes dramatically in autumn, and the human body can't adapt to the dramatic climate conditions for a while, so the above-mentioned discomfort symptoms are produced, that is, it suffers from "autumn meteorological allergy".

Modern meteorology shows that autumn is a season of active and changeable weather system, where cold and warm air meet frequently and weather elements change dramatically. The temperature and humidity in autumn are lower than those in summer, while the air pressure rises. Some susceptible people are particularly sensitive to the changes of these meteorological factors. Statistics show that urban residents are more prone to this disease than farmers, and women are more prone to this disease than men. Because urban residents live in high-rise buildings, deep courtyards and comfortable and stable environments for a long time, they have little contact with nature; But women have a keen sense of nature and can detect subtle changes in hormone secretion. In addition, women secrete less hormones than men, so their ability to regulate meteorological and environmental factors is worse than men.

How to prevent "autumn weather allergy"? First of all, we should strengthen exercise to improve the body's disease resistance and defense ability. In autumn, it is necessary to "freeze in autumn" properly, insist on cold water washing and cold water bath, and improve the adaptability of face, nose and throat to cold air. Secondly, watch (listen to) the weather forecast every day and keep healthy scientifically according to the weather changes; Increase or decrease clothes in time to prevent colds. Thirdly, pay attention to diet adjustment to adapt to the changes of seasonal solar terms, and eat more foods that moisten the lungs, promote fluid production, nourish yin and clear dryness, such as light tea, mung bean soup, various medicated porridge, fish, meat and eggs, kelp, laver, pears and so on. Finally, people with severe symptoms of "autumn weather allergy" can go to the hospital for treatment, among which monoamine oxidase inhibitors and 5-TA inhibitors are commonly used in drug treatment, and the effect is obvious.

Composition III on Meteorology: beginning of autumn on August 7th. Health experts warned that after beginning of autumn, the weather changed greatly and frequently, so the public should be alert to "weather allergy".

Zhang Dongsheng, an expert in health care, said that when the weather changes drastically, the time that the human body needs to adapt cannot be met, which will lead to the occurrence of "meteorological allergy", and autumn is the season when the meteorological conditions change obviously. On the one hand, compared with summer, the temperature and humidity in autumn are lower, but the air pressure is higher, which will affect the oxygen uptake of human cells. On the other hand, autumn is also a season with great weather changes. Cold and warm air often intrudes alternately, and the meteorological elements change violently and frequently, which is most likely to cause more serious "meteorological allergy". This disease is usually manifested as inattention, depression and anxiety, lethargy and fatigue, headache and dizziness, insomnia and sweating.

There is a folk saying in China that "spring is sleepy and autumn is lacking", which is actually a manifestation of "meteorological allergy". Zhang Dongsheng said that "lack of autumn" means that when the air is crisp in autumn and the climate is pleasant, many people feel weak, sleepy and unable to lift their spirits. "Autumn lack" is a sign of listlessness, which will affect people's work and life.

Many people mistakenly think that "autumn sleepiness" can be overcome by staying still or sleeping more, which is not the way to eliminate "autumn sleepiness". So, how to overcome the "autumn drought"? Health experts pointed out that to overcome the "lack of autumn", we should start with adjusting the laws of the human body and make targeted and reasonable adjustments in daily life, including getting up, eating and exercising.

Health experts specially reminded that after autumn, people should pay attention to the weather changes, increase or decrease clothes in time, strengthen physical exercise, enhance physical fitness, and at the same time maintain a nutritional balance to avoid "meteorological allergies" as much as possible.
