| Zusammenfassung |
| The Weather Research and Forecasting (WRF) model includes various configuration
options related to physics parameters, which can affect the performance of
the model. In this study, numerical experiments were conducted to determine
the best combination of physics parameterization schemes for the simulation
of sea surface temperatures, latent heat flux, sensible heat flux,
precipitation rate, and wind speed that characterized typhoons. Through
these experiments, several physics parameterization options within the Weather Research and Forecasting
(WRF) model were exhaustively tested for typhoon Noul, which originated in the
South China Sea in November 2008. The model domain consisted of one coarse
domain and one nested domain. The resolution of the coarse domain was 30 km,
and that of the nested domain was 10 km. In this study, model simulation
results were compared with the Climate Forecast System Reanalysis (CFSR)
data set. Comparisons between predicted and control data were made through
the use of standard statistical measurements. The results facilitated the
determination of the best combination of options suitable for predicting
each physics parameter. Then, the suggested best combinations were examined
for seven other typhoons and the solutions were confirmed. Finally, the best
combination was compared with other introduced combinations for wind-speed
prediction for typhoon Washi in 2011. The contribution of this study is to
have attention to the heat fluxes besides the other parameters. The outcomes
showed that the suggested combinations are comparable with the ones in the literature. |
