| Abstract: |
| Using the brightness temperature data of infrared and visible cloud picture,the estimate of the magnitude order of rainfall at the single site reveals that the effect of comprehensive utilization of infrared and visible cloud picture for the estimate of rainfall is better than that with utilization of only the infrared cloud picture, and the rate of forecast in void of heavy precipitation decreases clearly. |
| Key words: Brightness temperature Reflectivity pixel Rainfall estimate |
