Is there a big temperature difference between north and south after the Start of Winter?

After the Start of Winter, the north has already entered winter, while the south is still in late autumn, so there is a large temperature difference between the north and the south.
China is vast, spanning dozens of degrees of latitude from north to south, so there is a temperature difference between the north and the south, but the temperature difference becomes even more pronounced after the Start of Winter. In November, the average temperature in most parts of the Qinghai-Tibet Plateau, Inner Mongolia, and northern Heilongjiang reaches around -10°C. The temperature difference between Mohe in the northernmost part of China and Haikou in Hainan can reach 30°C-50°C. In many places in the north, it is dry, everything is withered, and it is bitterly cold. However, due to the impact of global climate change, some parts of South China remain green mountains and clear waters, with birds singing and flowers fragrant, warm and pleasant.
Mid and lower reaches of the Yangtze River:
After the Start of Winter, with the strengthening of cold air, the trend of temperature decline accelerates, and the north experiences widespread cooling. At this time, the average temperature in the mid and lower reaches of the Yangtze River is generally between 12°C and 15°C. The continuous rain has ended, and if a strong cold air rapidly moves southward, the temperature may drop by as much as 8-10°C, or even more, within a day. However, after the strong winds subside, the sun shines, and the cold air mass quickly changes, leading to a rapid recovery of temperatures. The temperature recovery and heat accumulation promote the next round of cold air bringing stronger cooling. Therefore, the weather of late autumn is coming to an end, and the obvious cooling makes this region enter the early frost period at the same time as it enters the best season for viewing red leaves, gradually entering winter by the end of November.
Northern parts of South China:
However, in the northern parts of South China, even if the cold wind passes through, the temperature will quickly rebound. On sunny and windless days, there is a saying that "October brings a small spring, without wind and warm and comfortable." Due to the impact of global climate change, this area often enters winter in December.
Southern parts of South China and below:
In the southern parts of South China, Taiwan, and islands such as Hainan Island, it has not yet entered winter in November. However, the temperature in November is not very high, with the highest temperature usually below 30°C. In addition, it is also possible that strong cold air affects the area, causing a significant temperature drop, although such occurrences have been rare in recent years.
