Analysis on Predictability of Meteorological Parameters of the 1 Km Resolution using WRF Meteorological Model in Southern Kyonggi-do Area
Keywords:Statistical analysis, Meteorological parameters, Horizontal Grid resolution, WRF model
WRF meteorological model is applied to investigate the mesoscale meteorological phenomena in southern Kyonggi-do area. Statistical analysis of meteorological parameters with 1-Km horizontal grid resolution was performed. For this purpose, the numerical simulation of WRF meteorology model is carried out during June in year 2011. The statistical analysis between real measurement and simulated meteorological parameters is done using IBM's SPSS Ver.21 program. The simulated results of 1 km grid resolutions were statistically analyzed with the observations in 4 surface meteorology weather stations of Songdo, Siheung, Yongin, Osan. The correlation coefficient(R2) between model simulation and real-measurement of air temperature and wind speed with high grid resolution (1 km) showed good agreement. Statistical credibility of the predicted meteorological parameters (air temperature, wind speed) permits us to conclude that the WRF meteorology model can be applied to analyze the regional air pollution dispersion in these regions.
