In order to investigate horizontal wind field in the boundary layer around Pusan area, wind speed and wind direction measured at 14 AWS(Automatic Weather Station), 1997, was used. The wind direction at PRMO(Pusan Regional Meterological Office) was showed that southwest and northeast wind dominated for spring and summer, northeast wind for fall and northwest for winter. Anticline flow was showed at `Gaekumm` which is located between Mt. Backyang(641 m) and Mt. Yumkwang(503 m) and affected on wind field at `Pusanjin`. The low wind speed and various wind direction was represented at the basin topography, `Buckgu`, `Jeasong`, `Ilkwang` and `Kijang`. The annual mean wind speed at 14 sites, 2.5 ms<sup>-1</sup>, was lower than that measured at PRMO, 3.9 ms<sup>-1</sup>. The wind direction analysis showed that the case of same direction in compare with that measured at PRMO is about 54% and case of opposite direction is about 12%. Annual and seasonal mean windrose showed wind direction is affected by not only synoptic weather state but also topography.
