The western coast of Korea, particularly in the Gyeongsang-do province, experiences moderate to high rainfall levels, ranging from 120 to 150 mm (4.7 to 5.9 in). In contrast, the central region, including Chungcheong-do, receives relatively lower amounts of rainfall, ranging from 100 to 120 mm (3.9 to 4.7 in). The southwestern region, Jeolla-do, experiences the lowest levels of rainfall, averaging around 90-100 mm (3.5 to 3.9 in) in May.
Frequency and Severity of Thunderstorms in May, Korea weather in may
The frequency and severity of thunderstorms in May are also influenced by the spring climate shift. As the temperature increases, the atmosphere becomes more unstable, leading to the development of thunderstorms. According to the KMA, the frequency of thunderstorms in May is significantly higher compared to other months of the year.
The frequency of thunderstorms in May is highest in the evening hours, around 6-8 pm, with an average of 15-20 thunderstorm events per month. In contrast, the morning hours, around 6-8 am, experience relatively lower frequencies, averaging around 5-10 thunderstorm events per month.

Understanding the Role of Cold Fronts and Warm Fronts in Korea’s Weather in May
In May, Korea is experiencing a transitional period from spring to summer, characterized by rapidly changing weather patterns. One of the key drivers of these changes is the movement of cold fronts and warm fronts across the region. In this section, we will delve into the mechanisms by which these fronts contribute to Korea’s weather in May, providing real-life examples of their impact on major cities.
The Formation Process of Cold Fronts and Warm Fronts
Cold fronts and warm fronts are formed when there is a significant difference in temperature and humidity between two air masses. These air masses can be either cold and dry or warm and moist, and they can come from different directions, such as from the north or south. When the front approaches, it brings with it a change in the weather, including changes in temperature, humidity, and wind direction.
Cold fronts, which are formed when a cold air mass moves into a warm air mass, bring with them a rapid drop in temperature, often leading to precipitation and strong winds. This is because the cold air is denser than the warm air, causing it to push the warm air upwards and create areas of low pressure near the surface. Warm fronts, on the other hand, are formed when a warm air mass moves into a cold air mass. They bring with them a gradual increase in temperature, often leading to precipitation and mild winds.
Case Studies: Seoul and Busan
To illustrate the impact of cold fronts and warm fronts on Korea’s weather, let’s consider two major cities: Seoul and Busan.
In May 2018, a cold front brought strong winds and heavy rainfall to Seoul, causing widespread disruptions to transportation and daily life. The front moved into the city from the north, bringing with it a significant drop in temperature and humidity. As a result, the city experienced a brief but intense period of precipitation, with some areas receiving over 100 mm of rain in just a few hours.
In contrast, a warm front that moved into Busan in May 2020 brought with it a gradual increase in temperature and humidity. The front moved into the city from the south, bringing with it a gentle breeze and a significant amount of precipitation. As a result, the city experienced a period of sustained rainfall, with some areas receiving over 200 mm of rain in a single day.
