IntroductionIntroduction
• The KMA EPS has been run operationally since May 2011 at global domain with N320 resolution (approximately 40 km in mid-latitudes) and 70 vertical levels.
• Total 24 ensemble members including control run and the initial condition perturbations are generated using an Ensemble Transform Kalman Filter.
• The upgraded KMA EPS gives better guidance to forecasters especially in prediction of typhoons.
• In this study, we compare the typhoon tracks from each operational centers participating in the TIGGE project for the year 2011 and 2012.
