In order to understand regional wind characteristics and to estimate offshore wind resources, a wind map of theKorean Peninsula was established using remote-sensing data from the satellite, U.S. NASA QuikSCAT which hasbeen deployed for the SeaWinds Project since 1999. According to the linear regression result between the windmap data and in-situ marine-buoy data, the correlation factor was greatly improved up to 0.87 by blending theremote-sensing data of QuikSCAT with U.S. NCEP/NCAR CDAS reanalysis data to eliminate precipitationinterference and to increase temporal resolution. It is found from the established wind map that the wind speed inwinter is prominent temporally and the South Sea shows spatially high energy density over the wind class 6. Thereason is deduced that the north-west winds through the Yellow Sea and the north-east winds through the EastSea derived by the low pressure developed in Japan are accelerated passing through the Korea Channel and formedhigh wind energy region in the South Sea; the same trends are confirmed from the statistical analysis of themeteorological observation data of KMA.
