变分法在校准天气雷达测定区域降水量中的应用

APPLICATION OF THE VARIATIONAL METHOD IN THE CALIBRATION OF REGIONAL RAINFALL MEASUREMENT BY WEATHER RADAR

摘要:

本文介绍了变分法校准天气雷达测定区域降水量的原理和实施技术,运用数字化雷达的彩色分层图象资料计算了5次暴雨过程的区域降水量,并对计算结果做了初步分析和讨论。

Abstract:

The basic principle and realization technique of the variational method used in calibrating weather radar regional rainfall measurements are introduced. Based on the layered color image data obtained by the digitized weather radar at Wuhan, the regional rainfall occurring in 5 rainstorms in 1987 and 1988 are calculated with this method. Thereafter, preliminary analysis and discussion are made of the calculation results.
