As the cold air around the country stagnated, the warm and humid air of the North Pacific High Pressure could not be overturned and remained in the south of Japan. As this stagnant front was frequently activated in the vicinity of Jeju Island, the rainy season continued for a long time, and it was cooler than usual due to frequent cloudy or rainy days.
