| Abstract: | The Variational Doppler Radar Analysis System(VDRAS)has been further developed through improving the quality control and preprocessing of radar data,the warm-rain parameterization scheme of a cloud-scale model,the interpolation and analysis method of meso-scale first guess,and the calculation schemes of meso-scale background for both cold-start and warm-start cycles,and applied to the real-time retrieve dynamical and thermal fields at low levels in support of the Beijing 2008 Olympics.The developed VDRAS re... |
