In East Asia, interaction between the rapidly mixingatmosphere and the slowly changing oceans are largely responsible for the monsoon, which affects Korea, China and Japan as elsewhere in the region. In order to better understand these patterns and to better prepare for their outcome, joint collaborative projects among these countries have been launched by their top meteorologists.

The climate of Korea is characterized by four distinct seasons: spring, summer, autumn and winter. The contrast between winter and summer is striking. Winter is bitterly cold and is influenced primarily by cold Siberian fronts. Summer is hot and humid due to the maritime pacific high. The transitional seasons, spring and autumn are sunny and generally dry. Temperatures in all seasons are somewhat lower than those at the corresponding latitudes in other continents, such as North America or Western Europe. The temperatures in Seoul, which is in the latitude of Richmond, Va., are closer to those in New York which is located 500 kilometers (300 miles) farther north from the latitude of Seoul.
 
Spring
Spring lasts from late March to May and is warm. Various flowers, including the picturesque cherry blossom, cover the nation's mountains and fields during this time.
Summer
The summer can be divided into two periods; jangma, a rainy period which occurs during the early summer months, and a hot and humid period which occurs in August. Rainfall during the summer time is characterized by heavy showers. Daily precipitation often exceeds 100mm (4 inches), with extremes topping 300mm (12 inches). Occasional storms caused by typhoons that pass through the peninsula sometimes cause a great deal of damage, although the loss of life is rare.
The daily high temperature often rises to over 37oC (100oF). Nights are also hot and humid.
Autumn
Autumn is known for crisp weather, much sunlight and the changing colors of tree leaves. Beginning in October, the continental air mass brings dry, clear weather. Traditionally, Koreans enjoy the season of harvest with festivities of chuseok which is one of the most important national holidays in Korea. It is often referred to as the Korean version of the American Thanksgiving. Autumn in Korea can be summed up with the simple words of an old Korean saying "The sky is high and the horses get fat."

Winter
Winter lasts from December to mid-March. It can be bitterly cold during this time due to the influx of cold Siberian air. Heavy snow in the northern and eastern parts of Korea makes favorable skiing conditions.
