Analysis of socio-economic value on typhoon affecting the Korean Peninsula for the last 10 years (2002~2011)

The Korean Peninsular has been affected by two or three typhoons from June to September each year. Recently, a typhoon genesis frequency over the western North Pacific has shown a similar or a decreasing trend compared with normal year. However, the damage by typhoons has dramatically increased because the intensity of typhoon affecting the Korean Peninsula is getting stronger (Park et al. 2006). It is said that typhoons give us a lot of damage, but they have positive effects : such benefits as to get water resources, to improve air quality, to remove harmful red tides, and to keep energy balance of the Earth moving from the equator to polar. However, there have been rarely attempts to understand these positive effects of typhoons. We need to make a comprehensive assessment of not only negatives but also socio-economic benefits in response to future water shortage under the climate change. In this study, a socio-economic value of typhoon that affected the Korean Peninsula for the last 10 years(2002~2011) is discussed from both points of the negative and positive view.
