Today s autumn equinox, the old man said, It s cold or not, just look at the autumn equinox , will

Whether winter is cold or not is not determined by the weather on the day of the autumn equinox, but by the amount of rain throughout the autumn and the humidity of the land.

Science says,"Evaporation takes away the heat, your body is dry, you don't feel cold, you take a bath or splash water on your body, you feel very cold, that is, when the water on your body evaporates, the heat is taken away, you feel cool. When people are hot, they will sweat, and as soon as the sweat evaporates, it will not be hot, and that is also evaporation takes away the heat. In autumn, the amount of rain is large, and the land is full of water, and in winter, when the soil is still very wet, the amount of water evaporation is large, and the heat on the ground irradiated by the sun is carried away by water evaporation, and it will be very cold.

If there is less rain in autumn and the land is dry in winter, there is less evaporation and less heat is taken away, so it should be a warm winter. The autumn of 2022 is dry, the amount of rain is small, the land is very dry, if there is not much rain after the autumn equinox, the winter of 2022 will be a big drought, there is no water vapor evaporation, and the winter should not be too cold.

Another theory is that the autumn equinox is divided into autumn in addition to the equinox of day and night. September 23 will usher in the "autumn equinox" solar term. Judging from the weather forecast, most of the autumn equinox in 2022 will be sunny and good weather across the country, but no matter whether it is sunny or rainy on the day of the autumn equinox, the temperature will become colder and colder.

At the same time, according to the experience of our ancestors, there was a saying in the past that if the northwest was blown on the day of the autumn equinox, then there would be more rain and snow in the lunar month, and there might be heavy snow to close the door, and the winter should be very cold.

Summary: Nowadays, carbon dioxide emissions are increasing year by year, even if countries around the world are vigorously advocating energy conservation and emission reduction, carbon neutrality and carbon peaking, it only inhibits the process of the greenhouse effect, and cannot reduce the generation of the greenhouse effect. Looking at the weather on the day of the autumn equinox, the old people said"The autumn equinox is sunny, a winter is green, the autumn equinox is cloudy, and the winter is warm, which is the opposite of evaporation.

It should be a sunny day when the rainfall is so large in autumn that it is sunny at the autumn equinox, and a cloudy day when the rainfall is so small that it is cloudy at the autumnal equinox. September 23rd is the autumnal equinox, let's see if it's sunny or cloudy.

It's going to be cold this winter. There is a saying that after a great heat, there must be a great cold. The authenticity is unknown, but judging from the current cooling range, it will be very cold, directly falling from more than 30 degrees to about 20 degrees, and it is only September.

Yes, it is true that this winter will be particularly cold, and as you can see from the day of the autumnal equinox, this year is a cold winter and it will be particularly difficult.

There is an old saying that it is called the autumn equinox, and the winter is very cold, that is, during the autumn equinox, the north wind is very strong, and the winter will be very cold, it will rain, it will snow, and it will become very cold. So you can observe it when the time comes.

When the autumnal equinox arrives, the weather will start to get colder.

On the autumn equinox, most of our country enters the cool and refreshing autumn. The cold air to the south meets the warm, moist air that is constantly falling, producing precipitation again and again, and the temperature drops again and again. As it is often said, when it comes to "one autumn rain and one cold", the daily precipitation after the autumnal equinox is not very large.

The Yangtze River basin and the vast areas in northern China have entered autumn one after another, and the average daily temperature has dropped to below 22 °C. The cold air mass in the north began to have a certain degree of strength. In most areas, the rainy season has just ended, with light winds and blue skies.

However, Guangdong and Hainan will not gradually cool down until the end of October and November. After the autumnal equinox, the sun shines directly into the Southern Hemisphere. The Northern Hemisphere receives less solar radiation, while the ground emits more and more heat, and the temperature drops faster.

Origin of the autumnal equinox solar terms:

Around September 23 every year, when the sun reaches 180 degrees of ecliptic longitude, it enters the "autumn equinox" solar term. The autumn equinox is the sixteenth of the 24 solar terms, except for the autumn equinox, the position of direct sunlight moves south, the northern hemisphere has short days and long nights, the temperature difference between day and night is large, and the temperature is falling day by day.

In ancient China, the meaning of "autumn equinox" has two meanings: one is to divide the four seasons according to the beginning of spring, the beginning of summer, the beginning of autumn and the beginning of winter in ancient China, and the autumn equinox day is in the 90 days of autumn, which divides the autumn equally. The second is that at this time, the day and night are divided into 24 hours a day, 12 hours each.

This day is the same as the "vernal equinox" day, the "autumnal equinox" day, the sun shines almost directly on the equator, after this day, the position of direct sunlight moves south, and the northern hemisphere has short days and long nights.

Yes, the weather after the autumnal equinox is getting colder day by day, and winter is getting closer and closer.

Autumn equinox solar terms, affected by a relatively strong cold air, most of the central and eastern parts of China from north to south have different degrees of cooling, many places in North China ushered in autumn in this round of cooling process, the change of the minimum temperature in the central and eastern regions is particularly obvious, and the autumn coolness in the night and morning period north of the Yangtze River is getting heavier.

At the time of the autumn equinox, most parts of our country have entered the cool autumn, and the cold air from the south meets the warm and humid air that gradually decays, producing precipitation again and again, and the temperature also drops again and again. As it is often said, it is time for "one autumn rain and one cold", but the daily precipitation after the autumn equinox will not be very large.

The autumnal equinox generally falls on September 22 or 23 every year. The climate in the south begins with this solar term before autumn. First, the sun reaches 180 degrees of ecliptic longitude on this day and hits the earth's equator, so the day is divided into 24 hours and night, 12 hours each; The global phenomenon of infinite diurnal and nocturnal.

After the autumnal equinox, the polar night range near the North Pole becomes larger, and the polar day range near the South Pole increases. The climate is characterized by a gradual increase in the temperature difference between day and night, and the temperature drops day by day, and it feels cooler, but the main thing is that the temperature difference between day and night is large, and the average temperature gradually decreases.

Since the autumnal equinox, the weather has begun to turn colder. On the day of the autumnal equinox, the day is as long as the night, which is twelve hours. From this day on, the days are getting shorter and shorter, the daylight hours are less, and the weather is getting cooler day by day.

As a transitional season when the weather turns from hot to cool, during the autumn equinox, most parts of our country have entered a cool autumn, and the cold air from the south meets the warm and humid air that gradually decays, producing precipitation again and again, and the temperature also drops again and again. As the saying goes, "an autumn rain and a cold, ten autumn rains to wear cotton", the production of rain during the autumn equinox also allows people to get rid of the warm weather, but although the precipitation in the autumn equinox is more frequent, the daily precipitation will not be very large.
