Typhoon Muifa Moves North Along China's Coast, Minimal Impact on Korean Peninsula... Rain Across the Country from 12th to 14th

Rain mainly in Jeju and the West Coast from the 12th to 14th
Outside the typhoon's influence area, due to atmospheric instability
More attention needed on the typhoon following Muifa
Typhoon No.14 may pass through the Korea Strait or Kyushu

[Asia Economy Reporter Han Jinju] Typhoon Muifa, the 12th typhoon of the season, is expected to pass through Shanghai, China, without significantly affecting the Korean Peninsula. Due to the warm air brought by the typhoon, the atmosphere will become unstable, resulting in rain mainly over Jeju Island and the western regions from the 12th to the 14th.

On the 12th, the Korea Meteorological Administration (KMA) held a briefing and announced that Typhoon Muifa is expected to pass through the sea near Shanghai, China, and head toward the Shandong Peninsula, and that the Korean Peninsula is not included in the typhoon's influence semicircle. However, warm air inflow caused by the typhoon will collide with cold northwesterly air, generating rain clouds and causing rain in various parts of the country from the 12th to the 14th.

Expected rainfall from the 12th to the 14th is over 120mm in the mountainous areas of Jeju, 30 to 100mm across Jeju Island, 10 to 50mm in the Jeonnam region, the western coast of Jeonbuk, the western coast of Chungnam, and the West Sea Five Islands (on the 14th), 5 to 30mm in the inland Chungcheong region, inland Jeonbuk, Gyeongnam region, and on the 14th in Incheon and the western coast of Gyeonggi, and around 5mm in the Gyeongbuk region and on the 14th in Seoul, inland Gyeonggi, and Gangwon Yeongdong. As the typhoon passes, high waves reaching 3 to 4 meters will occur mainly along the southern and western coasts and Jeju Island seas, and special caution is advised against swell waves.

As Typhoon Muifa moves along the Chinese coast, no damage from strong winds or heavy rain is expected. Woo Jin-gyu, a forecaster analyst at the KMA, explained, "Muifa will move northward along a corridor between the high-pressure system over our country and the vertically developed dry air from north to south, passing east of Taiwan and then skirting the coastal waters near Shanghai before making landfall near the Shandong Peninsula."

As of 9 a.m. on the 12th, Typhoon Muifa has a central pressure of 955 hPa and a maximum wind speed of 40 meters per second, classified as 'strong.' It is currently moving very slowly at 6 km/h and is expected to pass south-southeast of Shanghai around 3 a.m. on the 15th and make landfall south of the Shandong Peninsula around 3 a.m. on the 16th. Unlike Typhoon Hinnamnor, which turned east and crossed the Korean Peninsula, Muifa will move northward toward the Shandong Peninsula following the vertically developed dry air to the west of Korea.

More concerning than Typhoon Muifa is Tropical Depression No. 26, which has the potential to develop into Typhoon Nanmadol, the 14th typhoon of the season. This tropical depression is currently located near Kyushu and may pass over Korea. Numerical forecast models show a wide range in the timing of its northward movement, from the night of the 15th (UM model) to the early morning of the 17th (ECMWF model), and the path will vary greatly depending on the pressure systems formed over Korea. Typically, typhoons move northward along the edges of high-pressure systems, and depending on the location of the high pressure, the tropical depression's path will either go through the Korea Strait or near Kyushu.

Forecaster Woo said, "When the tropical depression transitions from stagnation to movement, the environment for its northward movement changes. If the high pressure is located along the eastern coast, the tropical depression will approach via the Korea Strait. If Muifa moves north slowly, the edge of the high pressure shifts eastward, causing the tropical depression to pass near Kyushu. Around the 14th to 15th, when Typhoon Muifa passes north of 30 degrees latitude and the tropical depression becomes active, the outline of the high-pressure system's position is expected to become clear," he explained.
