[Asia Economy Reporter Lee Hyun-joo] Following the record-long rainy season and the ensuing heatwave, a 'weather risk' is expected to return to the Korean Peninsula next week with the approach of a typhoon.

According to the Korea Meteorological Administration on the 21st, a tropical depression is likely to form near the waters off the Philippines on the 22nd to 23rd and develop into the 8th typhoon of the year, 'Bavi.' A National Typhoon Center official stated, "If the typhoon forms, it is expected to move northward around mid to late next week and affect our country," adding, "The path and intensity may vary depending on the position of the North Pacific High." So far, seven typhoons have occurred this year, with only the 5th typhoon, 'Jangmi,' affecting South Korea. Unusually, no typhoons formed in July, while one occurred in May and June, and five in August.

The number of typhoons expected to affect South Korea in the fall is anticipated to be at an average level. This assessment differs from last year's unusual situation when three typhoons consecutively impacted the country in September, causing significant damage. The National Typhoon Center forecasts that 11 to 13 typhoons will form this fall, similar to the average of 10.3, with about 1 to 2 typhoons (average 0.7) expected to affect South Korea, which is considered normal.

The heatwave is expected to continue into early autumn. The number of days with abnormally high temperatures in September is forecasted to be similar to or greater than the average of three days. The Korea Meteorological Administration predicted in its fall (September to November) outlook that "if the weather is clear in early September, the daytime sunlight will make it somewhat hot." Last September, the national average temperature was 21.8 degrees Celsius, 0.4 degrees higher than the average. Considering that it rained almost every three days due to typhoon influence, this year is expected to have less typhoon impact than last year, increasing the likelihood of higher average temperatures.

Relief from Scorching Heat Expected by Mid-September, Dry Heat Anticipated
Unexpected Variables May Arise

From mid-September, the scorching heat is expected to ease somewhat due to the influence of dry air approaching from China. Tropical nights are also expected to disappear at this time. In October and November, the region will mainly be affected by cold air from the north. Over the past decade, the central region has observed the first frost in early November and the first snow in mid-November, suggesting the possibility of a significant temperature drop.

However, all these forecasts could be wrong. Unforeseen variables frequently occur, such as the 'blocking' pattern that caused the record-long rainy season in the central region. The Korea Meteorological Administration noted that variables this fall could include typhoons, a significant temperature drop at the end of November, or conversely, extremely hot conditions.
