This study investigates the effects of horizontal resolution and surface flux formulas on typhoon intensity and 已刪除: impacts structure simulations through the case study of Super Typhoon Haiyan (2013). Three sets of surface flux formulas in the 已刪除: the 15 Weather Research and Forecasting Model were tested using grid spacings of 1, 3, and 6 km. Increased resolution and more 35 已刪除: different 已刪除: Both i reasonable surface flux formulas can both improve typhoon intensity simulation, but their effects on storm structures differ. A combination of a decrease in momentum transfer coefficient and an increase in enthalpy transfer coefficients has greater potential to yield a stronger storm. This positive effect of more reasonable surface flux formulas can be efficiently enhanced when the grid spacing is appropriately reduced to yield an intense and contracted eyewall structure. As the resolution increases, 20 the eyewall becomes more upright and contracts inward. The size of updraft cores in the eyewall shrinks, and the region of 已刪除: ed downdraft increases; both updraft and downdraft become more intense.
