Moreover, during the radar signal generation, static and dynamic characters of backscattering coefficient are set up, and time sampling of each clutter unit is computed with voltage character and power spectrum character, and the sampling signals are added in every distance gate to output time series. In addition, noise is modeled with a function of Gaussian stochastic process.

The results show that the simulated track of Bilis has about 39% and 16% improvement averaged during the 72 h forecasts after the assimilation of dropsonde and QuikSCAT data, respectively. The simulation of radar reflectivity is also improved. Similarly, the simulated track of Kaemi is improved by 26% and 21% by assimilating dropsonde and QuikSCAT data, respectively. However, the data assimilation appears to have no improvement in terms of radar reflectivity simulation for the Kaemi case.

With the assimilation of dropsonde/QuikSCAT data, the simulated environmental flow becomes more northerly/southerly, resulting in better tracks. The data assimilation also helps to produce better water vapor mixing ratio in the simulations of the Bilis and Mei-yu cases. As a result, the radar reflectivity is better captured in the simulations.
