In high-resolution numerical modeling, cloud microphysics parameterization schemes play an important role in typhoon forecasting by controlling the phase changes of the water. Simulated typhoon structure can be changed depending on how many hydrometeors are used in cloud microphysics schemes. In this study, thus, we investigate the sensitivity of track and intensity forecasts to cloud microphysics schemes in real-time typhoon forecast using a Weather Research and Forecasting (WRF) model. The WSM3 and WSM6 (WRF-single-moment-microphysics classes 3 and 6 cloud microphysics schemes are selected for the sensitivity test. Also, 24 forecasts for 12 typhoons occurred from 2012 to 2018 are conducted using high-resolution (2 km for core region) model with moving nesting method.
