Tourism weather forecast in southern Jiangxi

Since the end of August, the temperature has generally dropped in many parts of the country, and the temperature difference between day and night in the north has obviously increased. The hot summer has passed, and autumn is about to usher in a crisp autumn.

However, after the end of summer in southern China, there will often be short-term high temperature weather, which is also commonly known as "autumn tiger"!

So many people are asking, will the tiger come this autumn? Is it cold in autumn? Three agricultural proverbs give the answer!

0 1, typhoon Xuanlannuo brought heavy rain.

With the northward movement of Typhoon Xuanlannuo, the rainfall in the southeast coast began to increase.

As a super typhoon, the arrival of Xuanlannuo also led to more rain in Jiangsu, Fujian, Zhejiang and other places, and heavy rain occurred in some areas.

From September 5 to 6, there will be moderate to heavy rain in northeastern Zhejiang, southeastern Jiangsu, Shanghai, western Yunnan, southeastern Tibet, eastern Hebei, and northwestern Heilongjiang. Among them, there will be heavy rain in northeastern Zhejiang, southeastern Jiangsu, and Shanghai, and there will be strong winds of magnitude 5-6 or above in Jiangsu, Zhejiang and Shanghai.

From 6th to 7th, there will be moderate to heavy rain in Taiwan Province Island, eastern Guangdong, southern Fujian, southeastern Tibet, northeastern Kyrgyzstan and northeastern Heilongjiang, among which there will be local heavy rain in southern Fujian, northern Taiwan Province Island and northeastern Heilongjiang.

From 7th to 8th, there were moderate to heavy rains in western Sichuan, Gannan, southwestern Shaanxi, southeastern Fujian, south-central Guangdong, southern Hainan Island and Taiwan Province Island.

On August 8-9, there will be heavy rains in South China, western Sichuan Basin and southern Tibet.

As the saying goes, "an autumn rain and a cold", since the typhoon brought heavy rain, does that mean that the temperature will continue to drop next? Autumn tiger can't come?

Actually, it is not. Typhoon Xuanlannuo brought the "autumn tiger" to the north. What happened?

It turns out that after the typhoon moved northward, the southern region was affected by the peripheral descending airflow, and the subtropical high took advantage of it, so the Sichuan Basin to Jiangnan area will still usher in high temperature weather.

The so-called "autumn tiger" actually means that it is partly cloudy, and the weather is still hot after beginning of autumn. The main reason is that the subtropical high moves southward, the light is strong, and the weather is fine.

Due to the instability of atmospheric circulation, the subtropical high will temporarily move westward and northward, thus making the "autumn tiger" go down the mountain like a tiger, and there will be high temperature weather again.

Autumn tigers generally appear in the middle and lower reaches of the Yangtze River, as well as in the south of the Yangtze River and South China, and occasionally appear in the north, but their time is generally from the end of August to the beginning of September, while the south will last until the end of September or 10.

For example, from August 26th last year, Autumn Tiger started broadcasting in Jiangnan and South China, and it lasted until the end of September, which was hot enough to break records.

So, where will the autumn tiger affect this year?

According to the weather forecast, it is predicted that by Wednesday, the highest temperatures in eastern Sichuan, Chongqing, eastern Guizhou, Hunan, Hubei, Jiangxi, southern Henan and other places will reach above 35 degrees Celsius, and some places will be above 38 degrees Celsius.

Then, Jiangxi, Hunan and other places will continue to heat up.

However, experts also predict that autumn tigers are dry and hot, and their heat will not be as extreme as in summer, and the duration will not be too long, and the temperature difference between day and night will be large. Everyone should be prepared to add clothes to avoid catching cold.

Of course, as the direct point of the sun moves south, the summer heat in various places will inevitably gradually weaken, and as the cold wind in the north gradually moves south, the autumn tiger will naturally fade.

02. Is it cold in autumn? Three agricultural proverbs give the answer.

Meteorologically, the dividing standard of autumn is that the average temperature is greater than 10℃ and less than 22℃. If the average temperature is less than 22℃ for five consecutive days, then this time is the start date of autumn.

China has a vast territory, and there is a great difference between the north and the south in autumn. In high-altitude mountainous areas, autumn comes in June every year, and in August, most of the northeast, Inner Mongolia, most of the northwest, central Sichuan, central and western Guizhou, Inner Mongolia, Jinzhong and northwestern Shanxi have entered autumn.

Since September, it has been advancing southward to central Zhejiang, northwestern Jiangxi, central Hunan and northwestern Guangxi before autumn, reaching the south China coast in June 5438+ 10, while the southern coast of Guangdong and Guangxi, Hainan Island and Taiwan Province Island will welcome autumn in June 5438+065438+ 10.

Among the provincial capital cities, Hohhot usually falls in August 12, and Haikou is165438+1October 26th, with a difference of 106 days.

Then, some people will ask, is it cold this autumn? You can get the answer from three agricultural proverbs.

1, "It was chilly in summer, and I changed my cotton-padded clothes on August 15."

Literally, if the weather starts to get cold in summer, it means that the subtropical high has not brought the "autumn tiger" when it moves south, and the temperature drops faster. Maybe at the beginning of Mid-Autumn Festival, it is necessary to change short sleeves and put on thick clothes.

In fact, in the north where I live, I have already changed my short sleeves and put on my coat. I'm afraid it won't be too hot this autumn.

"When it was cool in late summer, Millennium put on a cotton coat."

Literally, if it rains continuously at the end of summer and the weather is cold, it means that there is more rain in autumn, and if there is a cold in autumn, it will not be too hot in autumn, so it may be necessary to wear thick clothes to keep warm during the Millennium solar term.

It is currently in the "late summer". For North China and Huanghuai, the temperature is really not too high, and autumn comes earlier.

3. "Mid-autumn rain is cloudy, white dew is accompanied by cold wind."

The so-called Mid-Autumn Festival is September. If it rains heavily in the Mid-Autumn Festival, even cloudy days are frequent, it is possible that the Millennium solar terms will usher in cold air and the temperature will drop faster.

From this point of view, although the "autumn tiger" caught up with the tail of the heat, it only affected some areas. The temperature in other places is still low, and you may cry in autumn!
