Effects of Terrain on Typhoon Sinlaku: Observations and Modelling Insights

This analysis investigates the terrain effects on Typhoon Sinlaku, particularly the impact of dynamic and hydrostatic balances during its approach. The Föhn effect on the lee side influences temperature and wind fields, potentially leading to increased RMS errors. We emphasize the need for more comprehensive observations to enhance model accuracy. This study provides insights into the RMS errors of temperature and wind fields for Sinlaku between September 11, 2008, 21:00 UTC and September 12, 2008, 16:06 UTC, underscoring the importance of terrain in typhoon dynamics.
