: With the approach of the solar term, most parts of the country are gradually ushering in the hottest period of the year. And this year's weather stage, a significant change is being staged - "rain from the south to the north". The subtropical high, carrying a large number of warm and humid airflows, is gradually advancing northward, causing the heavy rainfall belt in the south to follow in its footsteps and extend westward and northward.
Tomorrow's weather in detail: On July 4, the northward movement of the rain belt intensified
On July 4, the rainfall in the middle and lower reaches of the Yangtze River will weaken further, bringing a short intermission of rain to the region. At the same time, the pace of northward movement of the rain belt has accelerated significantly, and the vast areas north of the Yangtze River basin will usher in relatively concentrated rainy weather.
Specifically, southeastern Shandong, northern Anhui, northern Jiangsu, northern Sichuan Basin, and southern Shaanxi will become the main areas of heavy rainfall. Heavy rain or even heavy rains are expected in these places, and the public should pay close attention to weather warnings and take precautions. There will also be moderate to heavy rain in southern Heilongjiang, northern Jilin, northern Jiangsu and Anhui, southern and eastern Shandong, eastern Henan, and central and eastern Sichuan, and strong convective weather such as short-term heavy precipitation, thunderstorms and strong winds may occur locally.
The outlook for the day after tomorrow: On July 5, the rain will continue and the range of high temperatures will expand
The day after tomorrow, on July 5th, the rain belt moved north again, and the rain became more intense. The southeast of Tibet, the central and southern parts of Shandong, the northeast corner of Henan, the northwest of Jiangsu, and the north of the Sichuan Basin, all of these places have to be careful of heavy rain or even torrential rain, and some places may even be heavy rains.
This rain moved north, but it is good news for places like Shandong and Henan, they were so dry that they could quench their thirst now. However, you must also note that if it doesn't rain for a long time, the ground is as dry as a stone, and even if it rains, the ground may not be able to absorb much water. So, you still have to take it easy, don't just think about the rain, but also guard against the problems that may be bringing.
In terms of temperature, the distribution of hot weather will also change as the rain weakens in the south and the rain increases in the north. The hot weather in Jiangnan and South China will be further strengthened, and the coverage will gradually expand. The Yangtze River Delta region will be the first to feel the invasion of high temperatures and heat waves, and the maximum temperature in some areas may exceed 35°C.
However, it is worth noting that despite the increase in rainfall in the northern region, in some areas with no rain or sunny weather in North China and Huanghuai, the local maximum temperature may also reach about 33°C due to the influence of the northern high pressure ridge. Especially in the Daxinganling area in the northeast, the temperature may soar to 35~37 °C.
The weather wisdom in the agricultural proverb: the rain is drenched in the summer, and there is no need for cattle for 30 days
Speaking of which, I have to mention the wisdom of our ancestors. There is a saying in the agricultural proverb: "In the summer heat, it rains, and there is no need for cattle for 30 days." What do you mean? In other words, if it rains at the beginning of the summer season, the rain will be very abundant for the next period of time, and the cattle will have to rest, because the fields are too wet to work in the fields. No, this year's summer season has just arrived, and the rain has followed, and it seems that we have to get ready for a wet summer.
Epilogue:
To sum up, with the intensification of the trend of "south-to-north rain", the weather in the north and south of the mainland will show completely different characteristics. The southern region needs to be vigilant against the invasion of high temperature and heat waves, while the northern region needs to be prepared for heavy rainfall and strong convective weather. I hope that everyone can adjust their living and working arrangements in time according to the weather forecast to ensure a safe summer.
