卫星闪电定位校正

Study on Lightning Location Using Satellite Data

从卫星资料处理出发 ,分析了雷暴云在多通道卫星云图上的基本特征 ,提出了利用多通道数字化卫星云图判识雷暴云的方法。在判识出雷暴云的基础上 ,对其中心进行定位 ,并利用其定位结果 ,对闪电定位仪测得的闪电资料进行校正 ,以提高闪电定位仪的定位精度及卫星资料判别雷暴云的正确率。初步分析表明 ,利用卫星定位对闪电定位进行校正 ,对闪电资料的定位精度有较大的提高 。

Beginning with processing meteorology satellite data, this paper firstly analyzes the character of thunderstorm cloud in multi-channel satellite cloud images, and then proposes a method to distinguish thunderstorm cloud using multi-channel digital satellite cloud images. The center is located after the thunderstorm cloud is distinguished. And the location is used to update the lightning data measured by lightning localizer in order to enhance the location precision of lightning localizer and the accuracy of distinguishing thunderstorm using satellite data. The preliminary results show that it improves the accuracy of lightning location largely by updating the lightning location with satellite location. Good results are obtained from primary experiments.
