Classification of Agroclimatic Zones Using K-Mean Cluster Analysis Method.

This study was conducted to classify agroclimatic zones in South Korea. To classify the agroclimatic zones, such climatic factors as amount of rainfall from April to May, amount of rainfall in October, monthly mean air temperature in January, monthly mean air temperature from April to May, monthly mean air temperature from April to September, monthly mean air temperature from December to March, monthly minimum air temperature in January, monthly minimum air temperature from April to May, Warmth Index were considered as major influencing factors on the crop growth. Climatic factors were computed from monthly air temperature and precipitation of climatological normal year (1981-2010) at 1km grid cell estimated from a geospatial climate interpolation method. The agroclimatic zones using K-mean Cluster Analysis Method were classified into 6 zones.
