With the deepening of September this year, the meteorological situation in various parts of China has shown obvious polarization. From the current analysis of meteorological data, the weather conditions in the north and south will continue to maintain this trend in the next few days.
First of all, South China is currently mainly affected by the residual clouds of Typhoon Anemone, and heavy rainfall will continue today. The main rainfall areas will be Guangdong, Guangxi and Taiwan. Heavy to heavy rainfall is expected in these locations, while heavy rainfall is possible in some localized areas. Considering that the weather after a typhoon is usually accompanied by a certain degree of instability, this makes heavy rainfall in local areas more unpredictable. Local residents are advised to take protective measures, especially in low-lying areas such as mountainous river valleys.
In Fujian and Jiangxi, although precipitation has weakened significantly, residents of the region still need to be vigilant due to the lagging nature of disasters, especially recent flash floods and geological disasters.
For the southern parts of the country that are not covered by rain, such as Sichuan, Chongqing, Hubei, Hunan and other places, the hot summer weather will continue, and the frequency of high temperature weather will be high. In Chongqing, for example, the maximum temperature will remain between 36-37°C for the next three days, and the evening temperature will not be particularly low, and the minimum temperature may even approach 30°C. For those who wonder whether it is normal to be so hot in September, this phenomenon is actually more common in the south, especially in the white dew solar term.
In the blink of an eye to the north, with the arrival of the Bailu solar term, most areas have entered early autumn. In the northeast and Xinjiang, there has been a phenomenon of first frost. This cold air will gradually affect more northern regions. According to existing forecast models, a new wave of cold air will affect the east from the west over the next three days, and temperatures are expected to drop by 6 to 8 degrees in most areas, and may even drop by 10 degrees in some areas. Winds of magnitude 7-8 will also occur in north-central and northeastern China, and may reach magnitude 9 in some places.
It is particularly noteworthy that the mountainous areas of northeastern Inner Mongolia and northwestern Heilongjiang may have minimum temperatures below 0 degrees tonight and tomorrow morning. After entering the Bailu solar term, the influence of cold air in these places will be more frequent.
For the northeast and north of China, temperatures could set a new record low after autumn next week. In Changchun, for example, although it just set a new record for September yesterday, its temperature will start to decline from today. It is expected that by the 12th, the maximum temperature will only be around 20°C. Therefore, local residents are advised to start preparing warmer clothing to prevent the cold.
For people living in Jianghuai and Jiangnan, even if they have entered Bailu, they still need to be vigilant against the so-called "autumn tiger". In the south during the white dew season, especially in these two areas, autumn tigers are very frequent. The autumn tiger, also known as "returning to the south", means that the weather can become unusually hot and muggy for a short period of time, and such weather can last for days or even weeks. This short period of high temperature not only has an impact on health, but may also bring a lot of threat to crops. Therefore, it is recommended that local residents avoid going out for a long time during the day to maintain the water balance of the body, and at the same time pay close attention to the growth of crops and take timely measures.
For some parts of the north, especially those closer to the west and north, the impact of cold air will be more pronounced. The temperature difference between day and night in these places will get bigger and bigger, especially in the morning and evening, and you may feel a noticeable chill. Residents need to pay attention to adding clothes to avoid colds caused by temperature differences. Especially for the elderly and children, it is more important to be careful to keep warm. For farmers, mature crops should be harvested in time to prevent cold air from causing damage to crops.
At the same time, due to the strong cold air going south, there may be a significant cooling phenomenon from north China to Huanghuai, although not as strong as in the north, but for the residents of these places, it is also necessary to take countermeasures. With the autumn harvest approaching, it is recommended that farmers pay close attention to temperature changes and arrange the harvest time reasonably to avoid losses to crops due to temperature differences.
For the future meteorological trend, as the cold air moves south and the temperature gradually drops, the northern region will enter the real autumn, and the hot summer weather in the southern region will gradually decrease. However, due to the impact of global climate change, this year's temperature trend may differ from previous years. It is recommended that everyone keep an eye on the weather forecast, get the latest weather information in time, and prepare for their life, work and travel.
In summary, in the coming week, the weather conditions on the mainland will fluctuate, and different regions will have different climatic characteristics. No matter where you are, take precautions based on local weather conditions to keep yourself and your family safe.
