The bogussing method was further developed by incorporating the asymmetric component into symmetric bogus tropical cyclone of Structure Adjustable Balanced Vortex (SABV). is separated from disturbance field associated with establishing local polar coordinates whose center location cyclone. relative importance wave components in azimuthal direction evaluated, and only two or three large amplitude are added to components. Using Weather Research Forecast model (WRF), initialized vortex, track central pressure cyclones were predicted. Nine cyclones, which passed over Korean peninsula during 2010~2012 selected assess effect Compared cyclone, forecast error reduced about 18.9% 17.4% for 48 hours 72 forecast, while not improved significantly. results suggest that inclusion necessary improve cyclones.
