Typhoon No. 6 ‘Kanun’ passed through the center of the Korean Peninsula on the 10th. There has been no such path since 1951, when typhoon observations began. Even when typhoons approached the Korean Peninsula, most of them turned east due to westerly winds and passed toward the East Sea or Japan. However, ‘Kanun’ continued to advance north.
‘Kanun’ penetrated the Korean Peninsula because the ‘jet stream’ blowing from west to east and the northward timing of the typhoon did not overlap, and the typhoon, which was blocked by the ‘wall’ of high pressure and drifting in the sea, came up along the passage created in the center of the Korean Peninsula. is analyzed as Coincidence overlapped and created a typhoon path that had never been experienced before.
A typhoon is a meteorological phenomenon that balances the earth’s energy by sending heat energy from the equator to the poles. So it occurs in low latitudes and moves north to high latitudes. ‘Kanun’ also developed into a typhoon in the sea about 730 km west of Guam on July 28, and came up to Korea on the 10th via the Philippines, Taiwan and Japan. However, when typhoons reach the vicinity of Korea, most of them change their direction to the east. This is because Korea is in the westerly wind zone.
Hurricanes usually travel with the wind. The Korea Meteorological Administration said, “Kanun missed the ‘bus’.” The ‘bus’ here refers to the ‘jet stream’ blowing from the westerlies. The jet stream is a strong wind that blows above 30 to 35 degrees north latitude, blowing from west to east and smoothing the air flow throughout the earth. Unfortunately, the ‘Kanun’ did not meet the jet stream when it was heading north to Korea. The jet stream goes up and down from north to south, and at the time of ‘Kanun’ north, it was blowing from the upper part of the Korean peninsula. In other words, a passenger who was walking north and had to take a bus to go east at a certain point missed the bus and walked north. Without the help of the wind, the speed of movement was also slow. In fact, when the ‘Kanun’ reached the vicinity of Pyongyang on the 11th, its movement speed was limited to around 15 km per hour.
Kanun’ met the ‘wall’ twice as he climbed up. At one point, it was blocked by the Tibetan high pressure and could not reach China from the East China Sea. Afterwards, it moved eastward and was blocked by the North Pacific high pressure, so it turned to the north and headed for Korea. The path chosen by the typhoon is the ‘between road’ between the Tibetan high pressure and the North Pacific high pressure. It couldn’t penetrate the two giant air masses, and entered the passage created between them. Of course, the road was in the middle of the Korean Peninsula. Initially, it was expected that ‘Kanun’ would travel north along the East Coast. However, as the North Pacific high pressure expanded as it approached the Korean peninsula, it was pushed westward and approached the Seoul metropolitan area. Even after ‘Kanun’, if the conditions are met again, there is a possibility that the typhoon will penetrate the center of Korea again.
The center of ‘Kanun’ passed through the inland of the Korean Peninsula, but ‘extreme heavy rain’ was concentrated in Yeongdong, Gangwon. Heavy rain of 80 to 90 mm per hour poured. This is because the Gangwon Yeongdong area is in the right ‘danger radius’ of the typhoon and the topographical effect is added. Because typhoons rotate counterclockwise, winds from the east are stronger than those from the other side. In addition, the Taebaek Mountain Range blocks the east coast, so the typhoon pours more rain and passes over. It is observed that the recent increase in the water temperature in the east coast to 29 degrees has also made the rain cloud zone stronger. In Yeongdong, Gangwon Province, more than 150mm of rain will fall by the 11th.
‘Kanun’ was approaching the Korean peninsula with an intensity level of ‘strong’ and weakened to ‘medium’ when landing in the morning. In the afternoon, when passing through Andong, North Gyeongsang Province, it was reduced in size as a general typhoon and crossed the north and south. Typically, typhoons weaken when they pass over land먹튀검증.
