GPS Radio Occultation Data Assimilation in the AREM Regional Numerical Weather Prediction Model for Flood Forecasts

Figure 3

24-hour cumulative precipitation forecast difference between the quality control plan (REF_QC) and nonquality control plan (REF_NQC) (Figure 3a; unit: mm) and the difference in the initial values of the data assimilation analysis (Figure 3b: 700 hPa; Figure 3c: 500 hPa). The contour represents geopotential height increments (unit: GPM). The arrow vectors represent wind speed increments in m/s.
