Comparison of the ratio of QPEs/gauges from (a) RZ, (b) RKDP, (c) CA, and (d) VCCA approaches. One-hour accumulated precipitation in the range 2000~2100 UTC 8 August 2009 is used in the evaluation. The size of the circles represents the gauge observed rainfall amount and the color shows the ratio: the warm (orange), cold (blue), and white colors indicate underestimation, overestimation, and accurate estimation, respectively.
