Three Typhoons Approaching Simultaneously... Vapor Alert for the Korean Peninsula

Water Vapor Brought by Typhoon Affects Monsoon Front
"Typhoon No. 11 Path Must Continue to Be Monitored"

As three autumn typhoons form simultaneously, attention is focused on their potential impact on the Korean Peninsula. Even if the peninsula does not fall directly under the influence of the typhoons, the stationary front (monsoon front) can receive a large amount of moisture from the typhoons, resulting in heavy rainfall.

According to the Korea Meteorological Administration on the 29th, the three typhoons currently moving north are Typhoon No. 9 'Saola', Typhoon No. 10 'Damrey', and Typhoon No. 11 'Haikui'. Saola is expected to head toward China, while Damrey is set to move toward Japan.

Haikui formed on the morning of the 28th at 9 a.m., about 570 km north-northwest of Guam. Since it has only recently developed into a typhoon, its path is still difficult to predict. It is expected to move to about 150 km southwest of Okinawa by 3 a.m. on the 2nd of next month, and about 310 km west-northwest of Okinawa by 3 a.m. on the 3rd.

However, even if the typhoons do not directly affect the Korean Peninsula, they can influence the monsoon front. The moisture brought by the typhoons supplies the monsoon front, causing heavy rainfall.

In particular, if a typhoon remains over the sea for an extended period, it can continue to receive energy and strengthen its intensity. Saola, which stayed for a long time over the eastern sea of the Philippines, is expected to start moving northwest on the 29th, pass through southern Taiwan, and make landfall in China on the 2nd of next month. Accordingly, the China Central Meteorological Observatory has issued a yellow heavy rain warning for the southern region due to Saola's impact.

When Haikui moves north, it will meet the North Pacific High and blow strong winds toward the Korean Peninsula, causing precipitation nationwide starting from the southern region on the 1st of next month and spreading across the country by the 3rd.

Professor Lee Hyun-ho of the Department of Atmospheric Sciences at Kongju National University emphasized the need for continuous monitoring, saying, "Even if Typhoon No. 11 Haikui weakens and changes into a low-pressure system while moving north, if it affects the monsoon front near our country and continues to supply moisture, it can bring heavy rain to Korea."

Appearing on YTN's 'News Rider' that day, Professor Lee said, "Since the path of Typhoon No. 11 Haikui is very unstable, it is better to observe a bit longer before judging whether it will actually affect the front. Haikui will pass over the sea where Typhoon No. 9 Saola has already passed and mixed the waters, so we need to watch the interaction and how it will develop with a longer-term perspective."
