Abstract: A combined observational and numerical modeling approach is used to study the upstream track deflections of westward-moving tropical cyclones approaching the mountainous terrain of Taiwan. Although the standard deviations ...

Abstract: Numerical model simulations of west-moving tropical cyclones approaching and crossing the Taiwan orography are shown to contain many of the observed surface features. Vortices tend to track continuously around the northern ...

Abstract: Tropical cyclone (TC) track predictions from the operational regional nonhydrostatic TC forecast system of the Taiwanese Central Weather Bureau (CWB) are examined for their sensitivities to initial and lateral boundary ...

Abstract: In this study, the Advanced Microwave Sounding Unit (AMSU) data are used to retrieve the temperature and velocity fields of typhoons and assimilate them with the three-dimensional variational data assimilation (3DVAR) ...

Abstract: This paper introduces a relocation scheme for tropical cyclone (TC) initialization in the Advanced Research Weather Research and Forecasting (ARW-WRF) model and demonstrates its application to 70 forecasts of Typhoons ...

Abstract: n this paper, the impact of outer loop and partial cycling with the Weather Research and Forecasting Model?s (WRF) three-dimensional variational data assimilation system (3DVAR) is evaluated by analyzing 78 forecasts for ...

Abstract: blending method to merge the NCEP global analysis with the regional analysis from the WRF variational data assimilation system is implemented using a spatial filter for the purpose of initializing the Typhoon WRF (TWRF) ...
