摘要
本文用距离加权方法校准天气雷达估算降水强度和区域降水量。结果表明:经校准后,不但能使雷达探测到的结果与雨量计观测到的雨量比较接近,而且还能保留没有雨量计站的地方雷达探测到的降水强度变化。用时间外推校准技术来预测区域总降水量和降水量分布形式,也能保证一定的精度。
This article deals with a distance weighing method through which the rainfall intensity and the area precipitation amount detected by weather radar are adjusted. The result shows that not only the radar Measurernent agrees with the measurement of rain ganges but also the radar detected rainfall distributuin pattern in the no rainfall station can be retained after the adjustment. It is also found that accuracy can be guaranteed by time extrapolation technique forecaet area precipitation amonnt and rainfall intensity distribution pattern.
