Tomorrow the beginning of autumn has become the focus of everyone's discussion today, everyone's mood I can also understand, after all, the beginning of autumn as the beginning of the cool weather in autumn, in the face of the hot weather in midsummer, people have to look forward to the arrival of the cool weather soon. As the last solar term of summer, the Great Heat is also the time when the heat reaches its maximum. After the summer heat reaches the extreme, it gradually cools down, so after the great heat, the summer heat begins to go downhill. And the beginning of autumn is the solar term of the Great Summer Festival, and we have a lot to look forward to.
No, tomorrow will be August 7th, according to astronomical calculations, that is, when the sun reaches the ecliptic longitude of 135 degrees, the time is around 8:09, so this time is what we call the day and time of the beginning of autumn. Everyone looks forward to the arrival of the beginning of autumn, that is, we hope that the beginning of autumn can bring cold air when the season changes, and push the subtropical high in the south to the south.
On the occasion of the great heat and the beginning of autumn, there is a big difference in the weather between the north and south of the mainland. Under the influence of strong cold air, there has been widespread continuous rainfall in the north, so that the high temperature has eased, and the drought has also eased. However, under the influence of the subtropical high pressure, the vast areas in the south have experienced high temperatures and extremely hot weather, and people have been tolerating such hot weather for some time. And what people are most looking forward to now is the beginning of autumn to bring about the relief of high temperatures.
Tomorrow, August 7th, is the beginning of autumn, according to the latest weather forecast, affected by the westerly wind belt and the Siberian cold vortex, the continent from west to east, from north to south will have heavy rainfall, it is foreseeable that the high temperature weather in the south is expected to be relieved in mid-August.
Let's take a look at the specific rainy weather conditions from August 7th to 12th tomorrow, and see how the rain route goes. On what day will it rain south?
Tomorrow in autumn, the rainfall center will be in Shaanxi, Gansu and Ningxia, with local heavy rainfall. Let's take a look at how the rain falls:
Moderate to heavy rain occurred in parts of the Ili River Valley and Southern Xinjiang Basin in Xinjiang, southeastern and northern Tibet, southern and eastern Qinghai, southwestern Yunnan, central and eastern Gansu, central Ningxia, central Shaanxi, northeastern Inner Mongolia, south-central Shanxi, northeastern Henan, west-central and south-central Shandong, southwestern Fujian, and eastern Taiwan Island. Among them, there were heavy rains in parts of southern Ningxia, northeast Gansu, central and northern Shaanxi, and western Shanxi, and local heavy rainstorms. The cumulative rainfall can reach 100~160 mm. Some of the above-mentioned areas are also accompanied by short-term heavy precipitation, with the maximum hourly rainfall of 40~60 mm, and strong convective weather such as 8~10 thunderstorms and strong winds locally. It can be seen that tomorrow and autumn, the westerly wind belt high-altitude trough will bring heavy rainfall in Northwest and North China.
On August 8, the cold air from Siberia continued to move eastward, and there was heavy rainfall from the upper reaches of the Yellow River to the middle and lower reaches of the Yellow River. Let's take a look at how the rainfall is distributed:
Moderate to heavy rain occurred in parts of northwestern Heilongjiang, northeastern Jilin, most of Shandong, southern Hebei, south-central Shanxi, northeastern Henan, north-central Shaanxi, northeastern Sichuan, south-central and eastern Gansu, most of Ningxia, eastern and south-central Qinghai, eastern Xinjiang, central and southeastern Tibet, southern and western Yunnan, and most of Taiwan Island. Among them, there are heavy rains in some areas of northeast Henan, western Shandong, western Shanxi, northern Shaanxi, northeast and central Gansu, and local heavy rains. The cumulative rainfall can reach 100~130 mm.
From here we can see that the cold air has moved eastward and has reached the Huanghuai region. And it's still trending southward.
On August 9, under the influence of the southward movement of the Siberian cold vortex, heavy rain in Mongolia and North China was injected, and the weather of great cooling hit. Let's take a look at the distribution of rainfall in specific weather:
Moderate to heavy rain occurred in parts of western and southeastern Tibet, western Yunnan, northeastern Sichuan Basin, eastern Qinghai, south-central and eastern Gansu, southern Ningxia, southwestern and north-central Shaanxi, Hetao and south-eastern areas of Inner Mongolia, north-central and southern Shanxi, north-central and southern Hebei, north-central Shandong, Beijing, Tianjin, northwestern Heilongjiang, and most of Taiwan Island. Parts of northeastern Sichuan, northeastern Gansu, northern Shaanxi, Hetao and southern Inner Mongolia, and north-central Shanxi had heavy rain or heavy rain. The cumulative rainfall can reach 100~150 mm. Some of the above-mentioned areas are also accompanied by short-term heavy precipitation, and there are also strong convective weather such as thunderstorms, strong winds and hail locally.
Judging from the rainfall center three days after the beginning of autumn above, the Shaanxi-Gansu-Ningbo region has become the center of heavy rainfall, and there will be continuous rainfall, and the heavy rain and heavy rain are highly overlapping. In this case, we need to do a good job of preventing mudslides and landslides.
On August 10th, the cold air brought by the cold vortex continued to expand in North China, let's take a look at the rainfall distribution:
Moderate to heavy rain occurred in parts of western and southeastern Tibet, eastern and northern Sichuan Basin, northwestern Chongqing, most of Shaanxi, north-central Shanxi, east-central Inner Mongolia, north-central Hebei, Beijing, Tianjin, and western Liaoning. Among them, heavy rain in North China, Huanghuai and other places is more concentrated.
On August 11, the Northeast region was affected by the cold vortex, and there was heavy to heavy rain, and the south of the Yangtze River began to have a wide range of rainfall, and the high temperature and heat were slowly alleviated.
Moderate to heavy rain occurred in parts of western and northern Guangxi, most of Yunnan, western and southern Guizhou, western and southern Sichuan, Liaodong Peninsula, eastern Liaoning, most of Jilin, western and northern Heilongjiang, and northeastern Inner Mongolia. Among them, heavy rains began to occur in northeastern Inner Mongolia. In this way, the northeast region of the mainland will be the first to enter the cool autumn weather, the temperature plummets, the weather becomes colder, and people begin to wear down jackets to keep warm. However, the southwest and western parts of southern China have received more rainfall, and the hot areas have shrunk.
On August 12, the rain in the northeast and the vast areas south of the Yangtze River have rained weather, and the high temperature weather in the south has gradually eased. Specific rainfall areas:
Moderate to heavy rain occurred in parts of southeastern Tibet, western Sichuan, most of Yunnan, southwestern Guangxi, southwestern Guizhou, most of Fujian, central and eastern Hubei, northeastern Hunan, eastern Liaoning, southeastern Jilin, north-central Heilongjiang, and northeastern Inner Mongolia.
On August 13th, there was a strong rainfall belt in the south, let's take a closer look:
Moderate to heavy rain occurred in parts of southeastern Tibet, most of Yunnan, central and western Guizhou, southeastern Chongqing, western and northern Guangxi, north-central and western Hunan, most of Hubei, north-central and eastern Jiangxi, western Fujian, most of Anhui, southeastern Henan, central Jiangsu, northern Heilongjiang, and northeastern Inner Mongolia. It can be seen that there is occasional heavy rainfall in the Yangtze River basin and the vast areas south of it, and by mid-August, the high temperature will be eased.
