Table 2

The statistical scores of mean bias (MB), root mean square error (RMSE), and correlation coefficient (CC) obtained from two typhoons (72-hour data), one mei-yu (48 hours data), and long-term stratiform precipitation (120-hour data). The results from four approaches are included; they are only, only, combination of and without vertical correction (CA), and the vertically corrected composite algorithm (VCCA).
