Typhoon No. 9’Mysak ‘proceeds on a similar path to that of’ Maemi ‘in 2003, which is considered one of the worst typhoons in history since the first.
According to the Meteorological Administration, Typhoon Mysak has a very strong intensity with a central air pressure of 935 hectopascals (hPa) at 3 p.m. on Day 1, and a maximum wind speed of 49 m per second near central Japan.
Typhoon Mysak was predicted by the Meteorological Administration to be the closest to Jeju with an “all rivers” intensity of 47 meters per second around 8 pm on the 2nd. It is expected to land on the southern coast of Gyeongnam in the early morning. On the 3rd, it will penetrate the Yeongnam region, such as Busan and Ulsan, and then depart to the East Sea around 6-9pm on the same day.
The Meteorological Administration predicted that the entire country will be hit by typhoons on the 3rd, starting with the distant seas south of Jeju that night, and a lot of rain will fall. By day 3, it is expected to rain between 100 and 300mm in Gangwon Yeongdong, the east coast of Gyeongbuk, Gyeongnam, East Jeolla, Jeju Island, Ulleungdo and Dokdo, and up to 400mm or more on the east coast of Gangwon , the east coast of Gyeongsang and the mountains of Jeju Island. Seoul, Gyeonggi-do and Gangwon-do Yeongseo, Chungbuk and Gyeongbuk (excluding the east coast) are expected to receive 100-200mm, and Chungnam, Jeolla-do (excluding the eastern part of Jeolla) and the Sea of the West receive 50-150 mm of rain.
The maximum instantaneous wind speed estimated is 108 to 180 km per hour (30 to 50 m per second) in the coastal areas of Jeju and Gyeongsang, 72 to 144 km (20 to 40 m) in Yeongdong and the southern regions. from Gangwon (excluding Gyeongsang Coast and West Jeonbuk), and from 36 to 108 in other regions ㎞ (10 ~ 30 m).
In addition, it is anticipated that there will be a large wave 8 to 12 m above sea level. The Meteorological Administration said: “There is a very strong wind and high waves throughout the sea, and there is a concern about damage to marine facilities such as ships and fish farms, so pay special attention and make sure the ships flee to a place safe”.
In particular, there are concerns about flood damage at high tide. Until the 7th, it is a period in which the height of the sea water is high due to the astronomical tide (tidal wave caused by the attraction of celestial bodies such as the moon or the sun), and as the typhoon gradually approaches, It is a phenomenon that sea water is pushed in or out due to the weather. Looks like there will be more digging. The Meteorological Administration said, “Due to storm surges on Jeju Island, the south coast and the east coast, very high waves can flood breakwaters or coastal roads, so pay special attention to flood damage and safety accidents “.
◇ ‘Maisak’ Jinro, similar to ‘Maemi’, the number one custom in history
Typhoon Myssak and cicadas are considered typhoons with a similar route. Typhoon Maemi, which hit the Korean Peninsula in September 2003, registered a strong wind of 60 meters per second in the Jeju region, recording the highest wind speed in history. At that time, 4.2 trillion won property damage occurred.
As the wind speed at Maissac’s landing is expected to be stronger than that of the cicada, there is concern that it will be more powerful than the cicada.
Only in terms of central pressure, Myssac is similar to the Typhoon No. 8, ‘Bobby’, but unlike Bobby, who was influenced by the wind, it is expected to rain a lot.
The Meteorological Administration said: “The sea surface temperature raised by a typhoon is about 1 degree higher than normal, reaching around 30 degrees, and the turbulent current shows a way that warm seawater is introduced from the sea that passes as it moves north. ” If you go from north to south of Jeju Island, the central air pressure is reduced and it is very likely that it will become a very strong typhoon. “
