There is a typhoon in the season, which is not a rare thing. The temperature of the tropical Pacific Northwest is more than 28 degrees per year, and typhoons can be produced in 12 months a year. However, the typhoon at the end of December can enter the South China Sea and affect the mainland of China, which is very rare. Generally speaking, at the end of December, the cold air firmly controls the East Asian continent, and the South China Sea is swept by the northeast monsoon.

This year is different. In December, the South China Sea was very warm, and the subtropical high was also abnormally strong. It has joined the South Branch and made many “summer restorations” in Hainan, Guangdong, Fujian and other places. Many high temperatures broke the December record, the first few The asparagus even became the "summer solstice".

Of course, the December cold wave Not vegetarian. After the typhoon was sent to the South China Sea, the vice-high could not withstand the continuous blow of the cold wave and returned to the Pacific Warm Pool. The typhoon that lost its deputy high east wind protection will quickly disintegrate under the cold wave. However, on the one hand, the typhoon itself will attract cold air to the south, allowing the cold wave to penetrate into southern China, Vietnam and even the northern part of the South China Sea. On the other hand, the large amount of water vapor carried by the typhoon will drift to the southeast coast, bringing a lot of rainfall combined with the cold wave.

Because Therefore, this typhoon is purely for the cold wave, because it will be more wet and cold in the south.
