From the day on October 4, with the strong support of the Kuroshio Current in the Pacific Ocean, Typhoon Puppy bucked the trend and returned to the intensity of super typhoons in the ocean east of Taiwan, exceeding the expectations of all meteorological agencies. From 9 to 10 p.m. on October 4, the center of the little dog skimmed the offshore south of Lanyu, the wind pole of Taiwan Province, and the Orchid Island Weather Station at an altitude of 324 meters detected an extreme wind of 95.2 m/s, far exceeding 17, breaking the wind speed record in mainland China and even the whole of Asia.
This wind power has reached the wind speed standard of an EF5 tornado, which is equivalent to the oncoming wind on the roof of a 350-kilometer high-speed train running at full speed. In addition, Lanyu High School, which is 27 meters above sea level, measured a 10-minute average wind force of 55.3 m/s, 16 levels, and a maximum gust of 77.6 m/s, which also far exceeded 17 levels, breaking the historical record since the establishment of the weather station. After measuring these wind speeds, the anemometer of Lanyu collectively lost contact, and many meteorological instruments were damaged or blown away by strong winds, and Lanyu may have greater wind speeds.
No matter from what point of view, the puppy is the typhoon that hit Lanyu since meteorological records, leaving the highest wind speed record, which can be called the wind king of Lanyu. What is more noteworthy is that after skimming over Lanyu, the little dog did not crash straight into the central mountain range, but turned on the dodge skill and suddenly went south, landing at 8:20 am on October 5, but re-entered the sea 5 minutes later. In this way, the puppy avoided the sacred mountain of Gokoku, the highest part of the central mountain range, and the core structure remained, and the maximum wind near the center was only cut from 16 to 13.
The dog's unexpected strength and dodging skills have put Fujian and Guangdong under great pressure to defend against Taiwan. In fact, since the afternoon of October 4, the wind has been increasing and getting stronger along the central and eastern coasts of Shanghai, Zhejiang, Fujian and Guangdong. On the evening of October 4 and 5, the peripheral cirrus clouds of the little dog had come to the southeast coast, and brilliant and spectacular red clouds appeared in Fujian and Guangdong, which were all characteristics of the approaching typhoon. And next, the puppy still has some room for development, the northeastern South China Sea SST reached 28 degrees, and the vertical wind shear is weak, and the high-rise outflow is fully opened. Therefore, on October 6, the puppy may return to blood and strengthen again.
However, in addition to the Central Mountain Range of the Protector Mountain, Fujian and Guangdong have another windproof gate god, that is, cold air. As we said in the last program, the strength of this cold air is very strong, on the morning of October 5, from the grassland on the dam to the northeast mountainous area, a large area in the north is below zero, including Inner Mongolia Tuli River -9.3 degrees, Hebei Kangbao -8.5 degrees, Harbin Changchun Shenyang less than 3 degrees, Beijing 6.8 degrees.
In the Qilian Mountains of Qinghai and Gansu, the largest snowstorm fell in the second half of the year, and even a snowfield fell in northern Qinghai, a rare sight in early October. And this cold air not only affects the north, but also goes deep south, even breaking the Qinling Huaihe River, Yangtze River, Nanling, Wuyi Mountain, Sichuan, Chongqing, Guizhou, Zhejiang, Fujian and even Guangdong, Guangxi The temperature has dropped significantly.

As we all know, strong cold air can destroy the typhoon circulation, causing the typhoon to weaken significantly or even dissipate directly; However, after the weak cold air meets the typhoon, it will meet with its water vapor, making the rainstorm intensify. This time the cold air was strong in the north, but after reaching southern China, it was only moderately cold air. If the dog quickly strengthens to a strong typhoon before the arrival of cold air, then it may forcibly move north, make landfall in eastern Guangdong on October 7 and rotate in place, and its water vapor will combine with cold air to stimulate heavy rain or even exceptionally heavy rain in eastern Guangdong, southern Fujian and other places.
However, if cold air invades the typhoon circulation before the puppy strengthens, so that it cannot strengthen or even weaken, the puppy will be pushed away by the cold air after approaching the east coast of Guangdong on October 7, turn southwest, and dissipate after cruising the eastern Guangdong-Pearl River Delta coastline for a while. In this way, the rain in Guangdong Fujian will be greatly weakened, and the north-central part of Fujian and the Pearl River Delta region of Guangdong will be ordinary moderate to heavy rain, southern Fujian heavy to heavy rain, and eastern Guangdong heavy rain to heavy rain.

It can be seen that although the Protector God Mountain-Central Mountain Range and the cold air are joining forces to weaken or push away the dog, but in any case, the dog will have a serious impact on Guangdong and Fujian, and the heavy rain in eastern Guangdong is certain, and the wind in the Taiwan Strait will continue for a long time. At present, Shantou has announced the suspension of classes on October 6, in addition, the cold air is still accelerating south, and the places in Guangdong and Guangxi that have not cooled down must be supplemented and cooled. Please pay close attention to typhoons and weather trends, add clothes in time, and be careful not to catch a cold. In addition, new typhoon embryos have developed in the northwest Pacific, and a new round of powerful typhoon activity is brewing.
