Korean Peninsula

The Korean Peninsula is a peninsula in East Asia. It extends southwards for about 684 miles (1,100 km) from continental Asia into the Pacific Ocean and is surrounded by the Sea of Japan (also called the East Sea) on the east, the East China Sea to the south, and the Yellow Sea to the west, the Korea Strait connecting the first two bodies of water.

Until the end of World War II, Korea was a single political entity whose territory roughly coincided with the Korean Peninsula. Since the cessation of the Korean War in 1953, the northern half has been occupied by North Korea, while the southern half has been occupied by South Korea.

The northern boundaries for the Korean Peninsula are commonly (and tacitly) taken to coincide with today's political borders between North Korea and her northern neighbors, China (1,416 km along the provinces of Jilin and Liaoning) and Russia (19 km). These borders are formed naturally by the rivers Yalu/Amnok and Tumen/Tuman/Duman. Taking this definition, the Korean Peninsula (including its islands) has an area of 220,847 km² (85,270 sq mi).

The peninsula is called Chosŏn Pando (hangul:조선반도}} ) in North Korea and Han Bando (hangul:한반도}} ) in South Korea due to the different names for Korea.

Physical geography

Mountains cover 70 percent of the Korean Peninsula and arable plains are generally small and far in between the successive mountain ranges. The peninsula becomes more mountainous towards the north and the east, with the highest mountains (including Baekdu Mountain which stands at 2,744 m or 9,003 feet) found in the north.

The peninsula has 8,460 kilometres of coastline, and the south and west coasts are highly irregular in particular; most of the 3,579 islands off the peninsula are found along the south and the west coasts.

Climate

The climate of the Korean Peninsula differs dramatically from north to south. The southern regions experience a relatively warm and wet climate similar to that of Japan, affected by warm ocean waters including the East Korea Warm Current. The northern regions experience a colder and to some extent more inland climate, in common with Manchuria. For example, the annual precipitation of the Yalu River valley (600 mm) is less than half of that on the south coast (1500 mm). Likewise, there is a 20 °C difference in January temperature between the peninsula's southern and northern tips.

The entire peninsula, however, is affected by similar general patterns, including the East Asian monsoon in midsummer and the frequent incidence of typhoons in autumn. The majority of rainfall takes place during the summer months, with nearly half during the monsoon alone. Winters are cold, with January temperatures typically below freezing outside of Jeju Island. Winter precipitation is minimal, with little snow accumulation outside of mountainous areas.
