China Researchers Introduce New Model For Typhoon Forecasting Accuracy
Researchers have introduced key improvements in numerical weather models significantly enhancing the ability to predict typhoon tracks and intensities. The study led by Dr. Xiaowei Tan from the China Meteorological Administration (CMA) Earth System Modeling and Prediction Centre, focuses on refining typhoon forecasts by improving parameterization schemes used in operational models.
Published in Atmospheric and Oceanic Science Letters, the research presents modifications to the CMA-TYM operational model, incorporating a new parameterization scheme for friction velocity at the ocean surface and a two-moment cloud microphysics scheme. These updates replace the original methods, leading to better predictions for Typhoon Kompasu (2118).
Statistical analysis shows that the improved model e...
