In this study, the relationships between the wheat imports of South Korea and the climate of wheat production areas (the United States is selected as an example) during 1995-2014 are analyzed. While the wheat imports in South Korea have increased in the second half of the analysis period compared to the first half, wheat imports from the United States have decreased somewhat in the second half than the first half. The unit cost of wheat import from the United States is unstable in the second half due to the increasing tendency of unit cost of wheat imports since 2007 and the enhanced variability. Wheat yields of Kansas (winter wheat) and North Dakota (spring wheat) in the major wheat growing regions in the United States are affected by precipitation during growing period and high-temperature condition before harvest, respectively. The unit cost of wheat imports from the United States to South Korea was caused by the impact of fluctuations in precipitation of Kansas, rather than temperature condition of North Dakota.
